DESCRIPTION

Security monitoring with programmable mapping Field of the invention

The present invention relates to a security provision and method for monitoring the interior of an installation or residence.

Background

Domestic, office and other building security systems are often used to safeguard valuable possessions and for personal protection. These systems are typically implemented using different monitoring devices, such as cameras, motion sensors, numerical keyboards or contact sensors. Many buildings have multiple locations that are monitored for security purposes, requiring multiple monitoring devices at different locations. For increased security and functionality, monitoring devices can be configured to communicate with one or more central control devices. The central control device may, among other things, perform monitoring or recording functions, determine if the security of the building has been violated and whether to contact the security personnel.

A method of communication between the monitoring devices and the central control device is through a physical connection, such as electrical wiring or other. Using wiring to establish communication between security devices can be problematic for a number of reasons, such as the high cost of installation and maintenance. For example, exposed wiring is often unacceptable in a building, and therefore, the installation of the security system requires passing the cables through the walls of the building. This type of installation can significantly increase the time required to complete a security system installation. In addition, troubleshooting and repairing the security system can be difficult since there is limited access to unexposed wiring. Cable cost is another factor, especially in large buildings that require numerous monitoring devices.

A potential solution is to use wireless monitoring devices to reduce or eliminate the need for physical connections between the devices, however, wireless security systems also have a set of problems, such as the life of the battery. Ideally, safety devices are self-powered by, for example, a baton. Self-powered devices are safer since they are not subject to failure after loss of power in the building. They also require fewer installation problems since they do not need to be connected to a separate power supply; however, self-powered devices often have reliability problems due to the finite life of their power supply. Increasing the usable time of a power supply reduces the cost of replacing the power supply and increases the security of the entire system by having less potential downtime of the system or its components. Several recent developments have increased the potential power requirements of wireless security devices.

For example, the use of wireless communications in the home, office and other buildings has increased

constantly, creating additional problems with wireless security systems. One such

Problems is the growing potential for corrupt data due to interference between different wireless communication devices. This problem may also be present when an unauthorized person

try to disturb the security system by "interfering" with wireless communications using a device

wireless interference There are techniques to reduce unwanted interference, however, the implementation of some of the techniques results in increased power requirements. Two such techniques, both of which may result in increased power requirements, include increasing the transmission power or varying the frequency of the transmission.

Another problem with power requirements arises from the desire to have increased monitoring capabilities with smaller devices. As security systems have become more advanced, the power requirements of monitoring devices often increase. For example, monitoring devices that contain digital cameras require enough power to operate the camera, to store the digital instant in memory and to transmit the digital instant to the control device. The increased functionality of the monitoring devices, together with the desire to have smaller, less noticeable devices with less room for batting or other power supplies, has impacted the reliability of the monitoring devices.

Implementing a wireless building security system can be further complicated by industry or government regulations. A set of regulations of this type is imposed by the Federal Communications Commission (FCC). Current regulations cover numerous aspects of wireless communications systems including, but not limited to, a range of restricted frequencies, a minimum number of different

jump frequencies within the allowable frequencies, the maximum output power of a transmitter and a requirement related to equal use of the jump frequencies.

Attempts have been made to implement wireless security systems using a variety of methods. One such method is known from European Patent Application Publication No. EP 1 363 260 filed on May 6, 2003, entitled "It comes from communication radiofrequence between plusieurs mecanifs et systeme de surveillance mettant en oeuvre un tel proce". In addition, these methods still leave room for improvement.

To protect residents, employees, personal property and the like, security monitoring systems are used to monitor a variety of facilities and to detect the presence of unwanted intruders. Many of such security systems are connected to a central control unit and are monitored by an operator who can alert appropriate emergency services in the event of an unwanted intruder. Typically, a home monitoring security system includes a combination of detection devices and alarm devices and some also include cameras. To achieve maximum monitoring coverage these devices are distributed throughout the entire interior of the installation.

Security systems that use cameras are advantageous in that they can record the activity associated with a suspicious violation of the installation and can also be used by a monitoring station to avoid false alarms. In some cases, however, the cameras record the normal activities of the residents and / or employees of the facilities. The cameras also record activities that are falsely perceived to be security breaches such as pet behaviors and authorized users who have been accidentally locked up.

In specific situations, such as those that have the potential to violate the privacy of residents and / or authorized employees of the facility, such exhaustive recording by security cameras may be undesirable. Since unwanted intruders could violate the security of an installation while the inhabitants are present, it is necessary that the security monitoring system is functioning at all times. However, having cameras that are constantly put into operation to record the daily life and work routines of the inhabitants is a drastic invasion of the inhabitants' privacy, and is problematic with respect to false start-ups. In addition, the monitoring and recording of guest activities can be equally invasive.

In addition, the installation and configuration of the various cameras and devices often requires complex and time-consuming installation procedures.

US 2005/0162268 discloses a video surveillance system, in which at least one sensor condition defines an alarm status for each camera.

The problems discussed above have presented challenges to develop a system for monitoring domestic security and / or facilities that provides maximum coverage while minimizing one or more of the problems identified above.

Summary

On the contrary, the intention is to cover all modifications, equivalents and alternatives that fall within the scope and scope of the invention as defined by the appended claims.

Detailed description

The present invention is believed to be applicable to a variety of different approaches and arrangements to provide security services. The invention has been found to be particularly advantageous for addressing security monitoring needs in a residential or private office environment.

According to an example embodiment, a security system uses cameras to detect and identify intruders. The system includes an integrated camera / motion detector that is sensitive to intrusion sensors and other types of sensors / alarms (for example, a smoke detector, a carbon monoxide detector, a gas detector or a panic button) . For simplicity, the following analysis focuses on the integrated camera / motion detector that is sensitive to intrusion detection; However, the analysis is equally applicable to the integrated motion camera / detector that are sensitive to other types of sensors and alarms as well. The camera's intelligent behavior results in reduced power consumption and mitigates privacy concerns at various levels. A system user configures zones with at least one intrusion sensor (for example, door / window contacts, glass break detectors, hyper frequency radar detector or an infrared barrier) for each zone around the penimeter of an installation and configure corresponding cameras / motion detectors inside the installation. The intrusion sensors are activated (armed) by a system user, using, for example, a numeric keypad on a security panel, a remote control keychain, a telephone call using DTMF, a personal computer or a remote server. This allows a complete activation of the system when the system user leaves the installation as well as a partial perimeter activation of the installation when the system user (or other authorized person) is present. Therefore, when the user is present, the camera remains “turned off” unless it is properly operated by the motion detector. However, the motion detector also remains “off” unless it is armed by a corresponding intrusion sensor. Therefore, the cameras record images inside the installation when both an intrusion sensor has tripped and a motion detector has detected movement. In one implementation, the system user enters a code (for example, using a numeric keypad in a security panel) to identify the desired mode of system operation. In another implementation, the system user enters a system access code and then selects that desired mode of operation from a screen.

Another example embodiment relates to an integrated security arrangement. The arrangement includes an intrusion sensor to detect an intrusion in a target area of an installation, a second sensor to detect movement, an image capture device, and a base unit. The image capture device captures

images in response to an intrusion indication from the intrusion sensor and in response to an indication of movement from the second sensor. The base unit integrates a vision address of the second sensor and the image capture device, thus directing the second sensor to detect in the target area in which the images are captured by the image capture device.

Figure 1 depicts a building security system in accordance with an example embodiment of the present invention. Figure 1 includes building 100, control panel 102, and peripheral devices 104-110. The security system is implemented in such a way to reduce the power consumption of one or more of the control panel and peripheral devices in regard to wireless communications between the devices. When wireless communications are implemented, the devices use multiple frequencies (channels) as well as communication intervals. The devices can reduce the power consumption by using information regarding a specific frequency from the multiple frequencies used and the communication interval. For example, if the transmission devices modify their transmissions based on the information, a receiving device can reduce the power consumption by reducing the time that the receiving device is listening to a transmission from another device. Reducing power consumption, the system lends itself to the implementation of two-way communications between devices, which typically require more power consumption than unidirectional communications.

The irregular lines and ellipses found between the control panel 102 and the peripheral devices represent wireless communications between the control panel and the peripheral devices. Wireless communications can be implemented using appropriate frequencies. For example, it has been found that the frequencies of wireless communications in the radio bands (900 MHz, 2.4 GHz and 5.8 GHz) industrial, scientific and medical (ISM) are suitable for safety systems; however, alternative frequencies can be implemented according to the particular details of the system or its intended implementation.

The various elements of the peripheral devices and the control panel are implemented using one or more electrical circuit arrangements, processors, memory elements, software code, programmable logic devices, input / output interfaces or combinations thereof.

Building 100 represents an installation for which the building security system is implemented. Common implementations of building 100 include, but are not limited to, residential homes, retail stores, office buildings, government buildings, museums and other facilities. Typically, the security system will monitor several locations within building 100. Accordingly, Figure 1 represents various peripheral devices throughout the building.

Peripheral communications devices 104-110 may take the form of a variety of different devices, a few of which are depicted in Figure 1. For example, device 104 represents a window sensor that can detect, among other things, when the window has been opened or otherwise compromised; device 106 represents a camera for video capture; device 108 represents an alarm; and device 110 represents a mobile peripheral, such as a keychain for interconnecting with the control panel or other peripheral. Other example sensors include, but are not limited to, fire alarms, carbon dioxide sensors and panic buttons. These peripheral devices communicate with the control panel 102 using wireless communications.

Block 112 represents several elements that can be implemented in peripheral devices, including a transceiver block, a message protocol block, a synchronization block and a transmission anticipation block (Tx). Various embodiments of the present invention use one or more of these blocks. In such an embodiment, a peripheral device wirelessly transmits a signal using the transceiver block. The peripheral device uses information regarding a transmission period and the listening channel of the control panel in the transmission process.

In one embodiment, the peripheral devices transmit security information from the building to the control panel. For example, device 106 can transmit video images or status information of the device to the control panel, while device 104 can transmit information related to the window sensor.

Figure 1 represents the control panel 102 which includes a transceiver block, a message protocol block, a synchronization block and a transmission anticipation block (Tx). Various embodiments of the present invention use one or more of these blocks. In such an embodiment, the transceiver block is used to receive signals from one of the peripheral devices as a function of the communication intervals and the frequency that the control panel uses to listen to transmissions. The listening frequency is one of several potential frequencies available for communication between peripheral devices and the control panel. For example, the system may use a number of contiguous frequency intervals (channels) within a suitable frequency band. An example of such a use includes 25 or more channels in the ISM frequency band of 902-928 MHz. Numerous other combinations of channels and frequency bands are possible using the present invention.

Typically, the control panel and peripherals are implemented using a similar set of elements as represented by blocks 102 and 112; however, various components can be implemented differently. For example, the synchronization block can be implemented differently in the control panel in front of the peripheral devices where the control panel provides synchronization information to each of the peripherals and the peripherals must use the synchronization information to maintain synchronization using A local clock. In an example of this type, the peripherals compare the synchronization information with the local clock to compensate for any difference between the time frames of the peripherals and the time frame of the control panel. The synchronization information can take the form of a time index, such as a counter value, a current day time or any other time-based data that the peripheral can use as a reference for synchronization. In another example, the time index may be a reference within each transmitted message. Using such a system the peripheral device can compare when the message was received to when the message was expected. The peripheral device can also be configured to set the local clock using compensation for a timing error. For example, if the peripheral clock seems to run slower than the control panel, the peripheral can compensate by increasing the clock frequency or using a counter to compensate for differences between clocks.

The control panel and peripheral blocks are represented by having a transceiver; however, the system can be implemented using variations of receivers and transmitters. In some cases, a peripheral can be implemented with only one transmitter. In other cases, a peripheral can be implemented with only one receiver. Other implementations allow one or more of the control and peripheral panels to have both a transmitter and receiver (transceiver). Therefore, the transceiver is used herein to describe a receiver, transmitter or both a receiver and transmitter.

An embodiment of the present invention reduces the power of one of the devices as a function of the listening channel and a period of communications. The system reduces the length of time a receiver is active using the communication period and the listening channel to reduce the time window needed to receive the start of a transmission. When the receiver is not active, various methods of power reduction are used, such as removing power from the receiving devices or reducing or stopping selected functions (eg, amplification or processing).

Another embodiment synchronizes the various peripheral devices with the control panel. Synchronization can further reduce the active time of the transmitter since, for example, the transmitter can limit the transmission times in relation to the times for which the receiver is active. Such a reduction can be achieved since, for example, in many systems the transmission time cannot be shorter than the activation period of Rx of the receiver without knowledge of when the activation of Rx takes place; however, synchronization can reduce transmission times unless the activation period of Rx of the receiver.

In a specific example, the control panel sends periodic synchronization messages to the peripheral devices. A peripheral device that determines that it has lost synchronization with the control panel can increase the active time of the receiver to compensate for the loss in synchronization. In the event that the peripheral device no longer receives synchronization messages, the device can increase the active reception time to ensure that a transmission will be received from the control panel. The peripheral device can increase the activation time based on an expected accuracy of the local register (eg, local clock) of the control panel's time base. For example, when the expected accuracy of the local register is relatively high, the peripheral device increases the activation time only after the loss of several synchronization messages.

Some devices, such as a keychain or other handheld device (110), are portable and often withdraw from the wireless communication range of the rest of the system or may stop receiving or transmitting information in response to a period of inactivity. Therefore, portable devices often lose synchronization for as long as they cannot communicate with the control panel. Consequently, such portable devices frequently increase the activation time to compensate for the lack of synchronization between the portable devices and the control panel. The frequent increase in activation time often leads to a high rate of power consumption. To compensate, portable devices can be implemented to turn off transmission monitoring efforts until an external action takes place, such as a button is pressed.

In an embodiment of the present invention, the messages sent by the control panel are received by multiple peripheral devices simultaneously. Donate the message is not intended for all peripherals, the message may include information indicating what peripheral the message is intended for. The message may also be associated with a channel that the control panel uses for an acknowledgment message from the peripheral.

Figure 1A illustrates an exemplary embodiment of an integrated security system, in accordance with the present invention. A base unit 35 is located inside an installation and integrates a motion sensor 20, a camera 25 (eg, CCD camera), a data processor 30, and a communication interface 15.

In one implementation the motion sensor is a passive infrared sensor (PIR), which detects infrared energy in a target area and, in relation to a processor 30, recognizes changes in infrared ene (for example, temperature changes) to detect movement Depending on the size of the installation, multiple base units are located throughout the entire interior of the installation, a control panel 45 acting as a conventional communication hub for the installation. The control panel 45 interconnects with the base unit 35 via the communication interface 15. In the event that an intrusion signal 10 is received by the control panel 45 from an intrusion sensor, the control panel arms the sensor motion 20 to allow the motion sensor to activate camera 25 when motion is detected. The control panel 45 can also directly activate the chamber 25 (for example, without considering the motion sensor 20). In one implementation, the base unit 35 can receive the intrusion sensor 10 input through the communications interface 15. The sensor 10 input can therefore inform the base unit 35 or the control panel 45 to arm the motion sensor 20 and / or activate camera 25. When it is not assembled, motion sensor 20 will not be able to activate camera 25 but can still detect motion. The motion sensor 20 can detect movement in its field of vision, and once the motion sensor is assembled, the motion sensor can activate the camera 25. The motion sensor 20 and the camera 25 are positioned so that both Devices have overlapping detection fields. Therefore, the images of the origin of the detected movement are recorded by the camera without requiring any adjustment or intermediate alignment. The recorded images are processed by a data processor 30, which can be integrated with the motion sensor 20 and the camera 25 into a base unit 35 as shown, or can be located remotely and electrically coupled to the base unit 35 .

It will be appreciated that the data processor 30 can be implemented, for example, in the form of a high-speed processor such as a DSP (which includes an ALU) and / or a more general purpose processor that may be optionally programmed for (des) compression of video data. Therefore, various embodiments may include a variety of combinations of processing operations with one or more aspects of the processing operations performed on one or more local or remote processors. For example, both the storage and compression of video data can be performed in the base unit 35 by the data processor 30. When the processor is located remotely, the data storage can still take place in the base unit 35, but the compression of the video data could be implemented in the remote processor. Another embodiment may involve storing data in the base unit 35 without any compression of the video data. In addition, each of the above operations can be performed in combination with a central processor 55, as will be discussed further below.

In exemplary implementations, the base unit 35 is a wireless device operated at a stand that has both motion detection and image capture capabilities. For additional information on such a device, reference may be made to the provisional application filed with serial number 60 / 785,570 filed on March 24, 2006, entitled "Motion-Image Monitoring Method and Device." In certain implementations, the data processor 30 is configured to preserve the life of the battery communicating in accordance with appropriate energy saving protocols. For example implementations related to communicative coupling and data transfer between the devices previously analyzed in accordance with appropriate protocols, reference may be made to the United States application with serial number 11 / 389,673 filed on March 24, 2006, entitled “Spread Spectrum Communications for Building-Security” and European Patent Application Publication No. eP 1 363 260 filed on May 6, 2003, entitled “Precedence of communication radiofrequence between plusieurs gadgets et systeme de surveillance mettant en oeuvre a tel proceeds". The energy saving approaches also provide limited activation of the previously analyzed camera so that the privacy of the inhabitants of a residence or facility is greatly maintained.

The recorded images are transmitted through a two-way sensor communication path 40 to a control panel 45. In one implementation, the sensor communication path 40 is wireless and can be used, for example, as described in the two documents of patent incorporated above. The transmitted images can be encrypted by the data processor 30 before they are transmitted to the control panel 45. The control panel 45 includes a local storage area for the recorded images 50, the central processing unit 55, and a transceiver 60 The control panel 45 is located in the same installation as the base unit 35. The central processor 55 receives images from each of the base units located in the installation. Similar to the previous analysis, the central processor 55 can perform a variety of processing operations alone or in combination with the data processor 30. The images may optionally be stored in the data storage 50 for further review or processing. The control panel 45 includes a backup power supply to batter 65 in the case of a loss of power, for example, a natural disaster or an intruder that deactivates the power for the installation. The transceiver 60 additionally transmits signals that include system status reports or images recorded via a telephone channel 70 or cable channel 75 to outdoor monitoring facilities. Telephone channel 70 and cable channel 75 are not limited to PSTN or broadband channels; They can be part of a GSM / CDMA network. Outside monitoring facilities may include a private security company or a local law enforcement station.

In another example embodiment, when an intrusion sensor detects an intruder that violates the installation (for example, the door / window contact is triggered), the intrusion signal 10 is transmitted directly to the control panel.

control 45. Control panel 45 assembles one or more base units 35 in the same area where the intrusion signal originated (via sensor 10). For example, in response to the fact that a window contact is triggered in a room, the control panel 45 can arm the sensor 20 of the base unit 35 in that room, as well as the sensors of the base units located in adjacent rooms and / or the hallway outside the room. In this way the system can track intruders as they move through the entire facility. The base unit or units 35 respond as discussed above. In this system architecture, the control panel 45 is the master and the sensors and control devices (eg, numerical keyboards, keychains) are slave devices. The radio link in this architecture is a star topology with the control panel 45 in the center of the network. Branches include base units 35 and external links, for example, telephone channel 70 and broadband channel 75.

Other aspects of the present invention are applicable to a security system where a second sensor and the image capture device are not physically integrated into the same housing. In such an example, an embodiment is arranged with an intrusion sensor to detect an intrusion in a target area of an installation, a second sensor to detect movement, and an image capture device. The second sensor has a special relationship (for example, located close enough and aligned) with the image capture device to form a common field of vision, so that the fields of vision for both devices overlap without the devices being located in the Interior of a common accommodation. The image capture device captures images in response to an intrusion indication from the intrusion sensor and in response to an indication of movement from the second sensor.

In more specific embodiments, the various arrangements allow the devices to be placed in different ways to provide the common field of vision. For example, horizontal movement, vertical movement, or horizontal and vertical movement can be provided for each of the motion sensors and the image capture device, with their mirrored movements to maintain the integrated field of vision. More particularly, such mirrored movement can be provided using a cogwheel-like mechanism with devices to provide adjustments to increments in the horizontal and / or vertical directions; the person skilled in the art will appreciate that such adjustment can be implemented using servo-control motors or can be manually implemented using conventional position stabilizers that allow gradual / incremental rotation.

In a related embodiment, horizontal movement, vertical movement or horizontal and vertical movement can be provided for either or both of the motion sensor and the image capture device by conventional electronically implemented pan / tilt / enlargement operations or operations, with their coordinated movements to keep the field of vision integrated. For image capture, such pan / tilt / enlarge operation is commonly used in digital video recording devices. The motion detector can also be manipulated to modify the field of vision.

In more specific embodiments, the various arrangements can be implemented with a spatial relationship between the motion sensor and the image capture device using a common back plate to which each of the motion sensor and the image capture device is mounted and / or a template for aligning the motion sensor and the image capture device to be mounted on a wall, where contoured portions of the respective rear of the motion sensor and the image capture device can provide compensation to deflect the direction of view.

In other specific embodiments, the various arrangements allow such devices described above to be located so that their movement is pre-established before they are used or dynamically controlled while in use with automated or semi-automated coordination provided by the circuitry of control and / or personnel in a remote site center. Such coordinated movement, while maintaining a common field of vision, benefits a variety of monitoring and / or security applications.

According to an exemplary embodiment of the present invention, an intrusion sensor, such as a window or door contact, located on a penimeter of an installation detects whether the contact object, window or door, has been violated. If, for example, a window has been opened, the window contact (intrusion sensor) sends a signal to a corresponding integrated motion sensor / camera located inside the installation. Upon receipt of the intrusion signal, the motion sensor is armed and the integrated camera is set to a "ready" mode without starting recording. The motion detector remains armed and when motion is detected, the integrated motion sensor / camera starts up again. Once motion is detected, the camera turns on and captures images of the source of movement. Video images are sent to a central control panel for further evaluation. Additional evaluation may include determining (using manual or automatic, for example, machine visions) whether the origin of the movement is human, an animal such as a pet, or another moving object. If it is determined that the origin is human, the additional evaluation can reveal if any identifying images were captured, if the human is an intruder or an inhabitant of the facility, and facial recognition can be used to identify a previously unknown person who enters the installation.

In another example embodiment, the home entrance intrusion sensor (e.g. front door contact) corresponds to a delayed response motion sensor so that the transmission of the motion indication is delayed to adapt a numeric keypad of Security system control located near the entrance. In another area located in the fences, such as a kitchen, the movement indication is not delayed when motion is detected. The system recognizes that the movement detected in the nearby room (for example, a person who puts grocery bags in the kitchen) after a delayed detection of movement in the entrance area is probably an authorized user and will not sound an alarm during a predetermined length of time. If the system is not deactivated or reset before the predetermined length of time has expired, the alarm will sound. The number of nearby areas configured with such a relationship with the indication of delayed movement in the entrance zone should be limited to ensure that a real intruder is not given enough time to cross the premises without being detected.

In a further exemplary embodiment, the security system is equipped to capture an image of the person who assembles or disarms the system (for example, by entering a code in a security system control numeric keypad) to determine if the person is An authorized user. In one example, the captured image can be sent to a remote monitoring station for verification or to be stored for future reference. In another example, the security system can be programmed with images of authorized users and the system uses facial recognition to compare the captured image of the person trying to arm / disarm the system with the images of authorized users to determine if the person is An authorized user. If the image of the person matches that of an authorized user, then the person is allowed to arm / disarm the system. In one implementation, the security system control numeric keypad is equipped with a camera to capture an image of the person entering a code. In another implementation, a base unit 35 is located so that the camera of the base unit 25 can capture an image of the person entering a code in the security system control numeric keypad. In response to a code that is entered, the security system control numeric keypad activates camera 25 to capture an image of the person entering the code.

In a further exemplary embodiment, the security system is equipped with a self-diagnostic mode that is used to determine if the system is functioning properly. The system sends test signals representing intrusion detections by various sensors to the base stations 45 to determine that the appropriate sensors 20 are armed and / or that the appropriate cameras 25 are activated. The system can also enable each of the cameras 25 to capture an image to verify that the cameras are working. The results of the diagnostic tests can be visualized by the system user, recorded for future review or provided to a remote monitoring station.

Figure 2 shows a block diagram of a security system for mapping a plurality of sensors to a camera, in accordance with an example embodiment of the present invention. The control block 206 interconnects with the sensors 204 (ie, from the sensor sensor (1) to the sensor (N)) and the camera 202. The control block 206 receives input from the sensors 204 with respect to the sensor status. For example, a particular sensor may send a message to control block 206 in response to a window or door that opens. The control block 206 can then make a determination as to whether camera 202 should be activated. In one implementation, the control block 206 has a mapping or correspondence table that links one or more of the sensors to the chamber 202. In this way the response of the control block 206 to one or more of the sensors 204 may be limited. to sensors corresponding to the room or field of vision covered by camera 202. In some cases, control block 206 can receive images from camera 202 and also forward the images to a monitoring station using a telephone or network interface . In addition, in some cases, camera 202 can pan, tilt, zoom or otherwise change the field of vision to correspond to the particular sensor that was put into operation.

According to an exemplary embodiment of the present invention, sensors 204 and camera 202 announce their presence to control block 206 during an initialization stage. A system user can select from these devices when determining to which sensors the camera 202 must be configured to respond. In one example a graphical user interface can be used to allow ease of configuration. In another example, a graphic display of the location of the sensors 204 and the camera 202 can be used to allow a user to easily select and configure the system. Such configuration may be limited to the implementation during the installation of the security system, or it may be implemented throughout the use of the security system. For example, since the sensors 204 may be optionally wireless, it is possible that the sensors may move from time to time. This may be necessary when the function of a room changes or when the structure undergoes changes. In addition, sensors can be added or replaced at a later date.

In certain cases, camera 202 may operate in different modes or it may or may not be sensitive to sensors 204. For example, one mode may deactivate camera 202 completely, while another mode may activate camera 202. Such a mode includes that the control block 206 activates the cameras 202 in response to one or more selected sensors 204. In one embodiment of the present invention, different modes may have different sensors mapped to the camera 202. For example, one mode may have a sensor door mapped to

camera 202, while another mode may have both a door sensor and a motion sensor mapped to camera 202 (for example, when there should be no authorized occupants in the area). The system can be programmed so that a different code is used to identify each of these modes of operation. The system user enters one of the codes (for example, in a security system control numeric keypad) to select the desired mode of operation. In one implementation, the system user enters a security access code and then selects one of the programmed modes of system operation that are identified on a display screen (for example, by selecting a corresponding icon on a touch screen or by entering a number that identifies one of the modes). In another implementation, the system user enters a code for each mode of operation. This can be useful to allow different levels of access / mode settings for different users. For example, a child, friend or relative could be provided only with certain codes. This is particularly useful for controlling access to configuration settings or preventing access during restricted periods of time, such as late at night.

In a particular case, one of the codes may correspond to a sequence of image captures from various cameras. Therefore, a user of the system can initiate a sequence of camera shots to see different areas of the installation. This can be particularly useful to assure a user that there are no intruders or to monitor the status of an occupant (for example, a small child or otherwise vulnerable person) and the house in general (for example, to check fire or damage due to natural disasters).

In relation to the embodiments discussed herein as examples of the present invention, the camera can be activated in various ways. In general, camera activation includes activating the camera arrangements analyzed in relation to Figures 1-3. Therefore, when a sensor mapped to a camera arrangement detects a potential intruder, the motion detector of the camera arrangement is activated. If the motion detector detects motion, the camera can then be activated to capture snapshots of potential intruders. In an alternative mode, the camera can also be configured to immediately capture snapshots (for example, independently of the motion detector) in response to the detection of a potential intruder. This can be particularly useful for sensors that do not necessarily correspond to an intruder (for example, fire alarm) and for high security modes that do not implement a delay or second level of motion detection. In such a mode, the camera captures images regardless of the motion detection by the motion sensor. Another mode or setting could be used to distinguish between video capture (for example, consecutive shots over a period of time that can show movement, such as those stored in an MPEG file) and still image capture (for example, a or more individual images that can be stored using file formats such as JPEG) by the camera. Therefore, in response to a sensor and a selected mode, the system can be configured to 1) capture images after detecting movement in the field of vision, 2) immediately capture video, and 3) immediately capture a still image. These and other configuration options can be implemented using the various mapping features discussed in this document.

Figure 3 shows a block diagram of a security system for mapping a plurality of cameras to a sensor, in accordance with an example embodiment of the present invention. As discussed above, sensor 302 and cameras 304 (i.e., from camera (1) to camera (N)) communicate with control block 306. In response to input from sensor 302, it can be activated one or more of the cameras 304. As discussed in relation to Figure 2 and elsewhere in this document, the control block 306 can implement the desired correspondence between the cameras 304 to the sensor 302 using the database of mappings or correspondence table. This can be advantageous when the cameras provide different viewing angles and / or different fields of vision. For example, in response to the window sensor, several cameras can be activated, allowing security monitoring stations to visualize the entire room, and also having a better chance of identifying a potential intruder.

In an embodiment of the present invention, multiple cameras can be selectively linked to multiple sensors. For example, all cameras and sensors within a room can be linked together. Accordingly, the mapping of both Figure 2 and Figure 3 can be used with each other.

Figure 4 shows an example mapping or correspondence table, according to an example embodiment of the present invention. The data contained in the mapping table can be stored in a suitable memory device, such as flash, random access, hard drives and the like. In some applications it may be advantageous to use non-volatile memory to save against problems due to loss of power.

Column 402 contains from camera 1 to camera N. It should be noted that Figure 4 and the relevant analysis refer to camera 1 to camera N. As discussed herein, such cameras may include a motion detector integrated, and therefore, identification information as to whether the camera device includes such an integrated motion detector can be stored in the mapping or correspondence table. Column 404 contains sensors that are configured to activate the camera arrangement in the corresponding row. For example, sensors A, B and C activate camera 1, while

that sensors X, Y and Z activate camera 2. In this way a user of the system provides information as to the desired associations between sensors and cameras that result in a corresponding change in the data in the mapping table. For example, a graphical user interface can be presented to a user through a software application that runs on a processor. In one example, the processor is a general purpose computer, such as a personal computer or personal digital assistant, that can interface with the security system control device using, for example, a universal serial bus (USB) interface, Ethernet or similar. In another example, the processor is part of the control device.

Column 406 contains additional information regarding relationships between sensors and cameras. In one example, column 406 represents sensors that activate the corresponding camera when the security system is in a particular mode (ie, a different mode with which column 404 was associated). This is useful to distinguish between situations where the occupants are awake from when they are sleeping, the windows that are open from the inside of windows that are open from the outside, situations where the occupants are on vacation when they are not, and the like. In another example, column 406 represents sensors that need to be put into operation before the sensors in column 404 that activate a camera in column 402. Therefore, the sensors can be linked to each other, thus requiring that it be put into operation. operation of a succession of sensors before the activation of a mapped camera. In another case, column 406 represents sensors that are only activated after a certain delay. This can be particularly useful for activating sensors that are in the likely path of an intruder. For example, the camera in a bedroom can be activated after a window sensor is put into operation in the bedroom. After a sufficient delay to allow an intruder to pass through the room, a sensor can be activated from column 406 and corresponding to an adjoining room.

Column 408 represents additional data used to complement the mapping functions. In one example, column 408 may contain information regarding cameras that are activated only after a certain delay. This can be particularly useful for activating cameras that are in the likely path of an intruder. For example, the camera in a bedroom can be activated after a window sensor is put into operation in the bedroom. After a certain delay (for example, enough to allow an intruder to pass through the room) a camera can be activated in an adjoining room. In another example, column 408 may contain data containing delay values to activate the cameras or sensor of column 404 and 406. In another case, the data in column 408 may be used to indicate one or more security modes. for which the sensors and cameras stored in the respective mapping table columns are activated and deactivated.

According to another embodiment of the present invention, a combination of sensor events and the details of the sensor events can be selected to further define events for various cameras. In addition to requiring that a sensor be put into operation, combination events can be used to determine details, such as if a series of sensor events represented a person leaving or entering an area. More specifically, the order of sensor events and the absence of certain sensor events can be used to determine the address of a person traveling, the number of people present and other safety factors. Using information regarding the sequences of events, the system can be configured to avoid unnecessary video capture of normal occurrences, such as the exit of an authorized person from a secured area, while capturing even abnormal occurrences, such as the entry of a person to the insured area.

Additional data storage elements of the mapping table are possible (for example, similar to columns 406 and 408) and are only limited by practical considerations, such as complexity and storage space.

Figure 5 shows a logic flow diagram for implementing a process for activating security cameras in response to mapped sensors, in accordance with an example embodiment of the present invention. Block 502 represents a decision as to whether a sensor has been put into operation. The process expects in block 502 that a sensor is put into operation. If a sensor is put into operation, the process continues to block 504. Block 504 determines if the sensor is mapped to a camera. If the camera is not mapped to the sensor, the process returns to block 502 and expects another sensor to operate. If a camera is mapped to the sensor, the process continues to block 506.

Block 506 represents the potential activation logic. In the simplest case, the activation logic represented by block 506 does not need to be implemented. In such a case, the process continues directly to block 508. In other cases, various determinations, delays and other functions may be carried out in block 506. In a particular embodiment of the present invention, the information stored in a table Mapping is used to implement activation logic. As discussed herein, such information may represent different logic for different modes, delays before activation and the like. In some cases, the logic may determine that a camera should not be activated and the process continues to block 510. A case of this type is when the security system is in a mode for which the linked camera is not

activated In another example, the logic can activate other sensors before activating the camera. After determining that the camera should be activated the process continues to block 508 to activate the camera.

The process then checks additional cameras that are linked to the sensor put into operation as shown by block 510. If no additional cameras are found, the process returns to block 502. If an additional camera is found, the process continues to block 512 Block 512 is a logical block similar to block 506, where the process can generate branches to blocks 510 or 514. Block 514 activates the corresponding camera and returns to block 510 to determine if additional cameras are mapped to the sensor in operation. . In this way, a series of cameras can be activated in response to one or more sensors put into operation. This is particularly useful for activating cameras along a probable path of an intruder.

The various components of such a process can be implemented using one or more general purpose processors configured with appropriate software, one or more custom processors, programmable logic devices, analog / digital circuits, integrated circuit devices and combinations thereof.

Figure 6 shows a logic flow diagram used to activate cameras for a security system, in accordance with an example embodiment of the present invention. In a particular embodiment this logic can be implemented instead of activating the logic blocks 506 and 512 (for example, as a function call in a software routine). The process begins in block 602 where it continues to block 604. Block 604 can implement a delay before activating any cameras. If no delay is required, the delay stage can be omitted. In one example, the delay can be a delay set for each camera. In another example, the delay may be a function of data stored in the mapping table along with other variables, such as the current mode of the security system. After the delay is implemented, if any, the process continues to block 606. In block 606, a determination is made as to whether the sensor is configured to activate the camera in relation to the current security mode. This can be achieved, for example, by comparing the data in the mapping table with the current security mode. If it is determined that the camera should not be activated in response to the sensor, the process is exited as shown by block 614. Otherwise the process continues to block 608.

In block 608 a determination is made as to whether additional sensors are linked (for example, required to be put into operation) in relation to the corresponding camera. This is useful for configuring the camera so that it only comes into operation in response to more than one sensor. If it is determined that no additional sensors are linked, the process continues to block 612 where the corresponding camera is activated. The process is then exited as shown by block 614.

If at least one additional sensor is linking, the process continues to block 610. In block 610 a determination is made as to whether the linked sensor is put into operation. If the linked sensor is not put into operation, the process can wait in block 610 until the sensor is put into operation. In some cases, it is desirable to reset or exit this state even if the linked sensor is not in operation. This can be achieved using various methods. Using such a method, a timer can precipitate the output of state 610. Using another method of this type, the process leaves state 610 in response to an external event, such as resetting the sensor or sensors put into operation. If the linked sensor is put into operation, the process returns to block 608 to check other linked sensors.

Figure 7 shows a block diagram of an interface for implementing different levels of access to a security system, for an exemplary embodiment of the present invention. Figure 7 represents a security interface 704 that provides two levels of control / access 706 and 712 for different users of the system. Different levels of control can be particularly useful for simplifying the control aspects available to an end user 702, while allowing additional functionality to be configured by a qualified 710 installer. Control levels can also be particularly useful for reducing the risk of an end user 702 improperly configures the security system, limiting control of certain aspects of the system. Therefore, the security system can be configured to maintain a minimum level of security, regardless of the configuration changes of the end user 702.

Security interface 704 is accessed using a number of different mechanisms. A non-exhaustive list of acceptable interfaces includes a general purpose computer connected via Ethernet, USB or similar, numerical keyboards, touch screens, voice response systems and key chains. Security interface 704 provides a different level of access depending on the user. In one example, the user's credentials can be determined by a username and / or password, electronic identification cards, wireless transmitters, biometric identifications or the like. Once the user's credentials are determined, the user is granted an appropriate level of control through the system as shown by blocks 708 and 714. The number of different control and user levels may vary depending on the particular application. . For example, there may be a first level (for example, full access) for a system installer; there may be a second level (for

for example, limited access) for domestic owners and there may be a third level (for example, change of mode only) for children of domestic owners.

Figure 8 shows a block diagram of an interface for implementing different levels of access to a security system, for an exemplary embodiment of the present invention. Figure 8 depicts a security system 808 that allows the end user 802 access using the end user interface 804 and the qualified installer 814 access using the qualified installer interface 812. Providing multiple interfaces to the system with different levels of control can be further protected. . For example, the subset of control features 806 could be provided through a touch screen or local computer. Such interfaces may be subject to potential security risks (for example, hacking the computer remotely or obtaining access to the touch screen before when the system is not armed) that the security system may compromise. By limiting the control available through the end user interface, global security can be improved. A higher level of control (for example, installer control features 810) can be provided using a more secure interface method. For example, the interface can only accept a security card that is controlled by the installer, or it can only accept instructions from a known server or port of entry. Therefore, the security system is not completely compromised simply by compromising the end user interface 804. This can also be particularly useful for limiting complexity by essentially hiding certain end user configuration options.

Figure 9 shows a block diagram of another interface that provides administrative monitoring of configuration settings for a security system, for an exemplary embodiment of the present invention. Figure 9 represents an end user interface 904 that allows the end user 902 to access the access control logic 916. The end user interface 904 sends data to and from the end user 902 using the network 906. The end user can configure control logic 916 and monitor the status of sensors 912 and cameras 914 through such data transfers. The off-site administrator 908 provides monitoring functions for all or a subset of user transactions. For example, the off-site administrator 908 can monitor configuration settings so that control logic 916 verifies that the system is not compromised due to user error or an unauthorized person. In some cases, monitoring may be limited to critical functions, such as deactivating sensors 912 and cameras 914. In other cases, monitoring can cover all transactions. This monitoring can be achieved using an automated process that follows an established rule designed to identify potential problems. Monitoring can also be achieved by using (alone or in combination with automated processes) human operators who observe potential problems.

Although certain aspects of the present invention have been described with reference to several particular example embodiments, those skilled in the art will recognize that many changes can be made thereto. For example, aspects of the underlying patent documents (for example, aspects that provide integration into the fields of vision, and details of implementation of the integrated image capture and motion detection devices).
