Description

  The present invention relates to a security system that visually recognizes an image obtained by imaging a predetermined monitoring area and, when a problem occurs, reports that fact and guards the monitoring area.

  In recent years, crimes centered on empty nests and the like have been increasing rapidly, and along with this, the number of security system contracts has been increasing. As one of such security systems, if a problem occurs when an image taken by a monitoring camera installed at the entrance of a house or in a store is viewed through a predetermined monitoring monitor, A security system that guards a predetermined monitoring area by reporting the fact is known. As this type of system, the images captured by the surveillance camera are compared in units of frames or in units of time, and if the difference is equal to or greater than a predetermined threshold, it is determined that there has been a change in the image. There are things that report that. At this time, as a target to be compared in frame units or time units, a point image change or a color change of a pixel can be cited. In the monitoring system, when a change is detected based on a point image change of a pixel, an intrusion of a suspicious person can be detected, and when a change is detected based on a color change of a pixel, a fire or the like Can be detected.

  By the way, in the conventional security system, it is the present situation that security is relied on the surveillance camera provided in the surveillance area and other various sensors provided alone, and there is a means for more reliably detecting abnormal situations. It is desired.

  In addition, the security system can detect the intrusion of a person or the occurrence of a disaster in the surveillance area, but only reports that it has been detected, so what kind of situation is actually occurring? It could not be confirmed, and even when the situation was unrelated to crime or disaster, there was a case where it was erroneously reported, and a situation that forced useless dispatch by a security company was invited.

  Furthermore, in this type of security system, it is also possible to transmit the video of the site to the security company at the same time as the notification. In this case, in such a security system, the situation at the site can be accurately grasped by visually checking the video by a security company. However, in a system that uniformly transmits such video to a security company, there is a risk of infringing on the privacy of the user, and many users dislike it.

  In order to solve this problem, it is also possible not to transmit the on-site video to a security company, but to transmit it to communication devices possessed by users such as mobile phones and personal digital assistants (PDAs) in recent years. It is done. However, in such a system, although it is possible for the user to accurately grasp the situation at the site, for example, even when the intrusion of a suspicious person is detected, the user is in a remote place In such cases, it is not possible to take measures that immediately threaten the person, and it is assumed that damage cannot be avoided.

  Furthermore, with conventional security systems, even if a contract is made for a system provided by a security company, etc., it often takes a long time from the notification to the arrival of the security guard, which has led to the eradication of user anxiety. There is no current situation. In spite of this situation, the security system has not been able to break away from a model in which a security guard rushes based on a report through a telephone line for illegal intrusion or the like.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  This embodiment is a security system that guards a monitoring area by visually recognizing an image obtained by imaging a predetermined monitoring area and, when a problem occurs, reports that fact. This security system can realize a very high-precision and powerful monitoring system by attaching various warning sensors to a monitoring camera that images a monitoring area.

  As shown in FIG. 1, the security system includes a monitoring camera 1 installed so as to be able to image a predetermined monitoring area such as a front door of a house or a store, and an image obtained and acquired by the monitoring camera 1 A monitoring server 2 for storing the received voice, a portable terminal 3 possessed by a user of the security system, and a centralized notification management server 4 provided in a centralized notification management center of a predetermined public organization and / or private organization In addition to the report central management server 4, the terminal 5 is provided at a report destination arbitrarily set by the user, and these devices are connected via a predetermined network such as the Internet. .

  Although not shown in particular, the monitoring camera 1 performs an image recognition process such as a difference method on a captured image in addition to a predetermined optical system for imaging the monitoring area, and detects a change in the monitoring area. The sensor includes a communication module for performing communication between the monitoring server 2 and the mobile terminal 3. The monitoring camera 1 is additionally provided with a microphone 6 that is a sound acquisition unit that acquires sound in the monitoring area and a speaker 7 that is a sound output unit that outputs sound.

  Such a monitoring camera 1, for example, monitors a monitoring area on a 24-hour basis, and performs image recognition processing such as a difference method by an image sensor on a captured image to acquire a video of the monitoring area. Or the change of the said monitoring area is detected in real time by comparing by a time unit. As such an image sensor, for example, a technique described in Japanese Patent Laid-Open No. 2003-219225 and other known techniques can be employed. Here, when the comparison target is a point image change of a pixel, the monitoring camera 1 generates a new point image at the coordinates of the imaging range in response to a new object entering the monitoring area. If the change area is equal to or greater than a predetermined value, it can be determined that the person is a person and illegal intrusion has occurred. In addition, when the comparison target is a color change, for example, when a fire occurs in the monitoring area, the monitoring camera 1 changes the color of the pixel in the coordinates of the imaging range depending on the color of flame or smoke. If the change area is equal to or greater than a predetermined value, it can be determined that a fire has occurred. At this time, even if the monitoring camera 1 can determine a person or the like, the intrusion time may be a predetermined time or more because it may be a person who is not related to a crime such as a mere passerby. If not, the person may not be treated as a suspicious person. Note that the monitoring camera 1 may perform either one of the point image change and the color change of the pixel as a comparison target, or may perform both of these in parallel. In addition, when the surveillance camera 1 initially captures an image of the surveillance area at a wide angle and detects a change, the coordinate area in which the change has occurred can be enlarged by a zoom-in function or the like to obtain a detailed video. . The monitoring camera 1 transmits the video when the change in the monitoring area is detected to the mobile terminal 3 together with the notification of the occurrence of the abnormal situation, and transmits to the monitoring server 2 and stores it.

  In addition, the monitoring camera 1 acquires the sound of the monitoring area by the microphone 6 and transmits the sound when the change of the monitoring area is detected to the mobile terminal 3 together with the video and to the monitoring server 2. To send and memorize. Furthermore, the surveillance camera 1 can also output the voice of the user who is the owner of the mobile terminal 3 transmitted from the mobile terminal 3 via the speaker 7. In other words, the surveillance camera 1 is configured to be able to perform two-way communication with the mobile terminal 3, and for the purpose of threatening illegal intruders, the video and audio when a change in the surveillance area is detected. When the user of the received portable terminal 3 transmits his / her voice, the voice can be received and output via the speaker 7. The surveillance camera 1 can also output a pre-recorded voice via the speaker 7 in response to a user instruction and / or automatically when a change in the surveillance area is detected.

  Further, the surveillance camera 1 is provided with a predetermined warning sensor 8 for detecting an abnormal situation. The alert sensor 8 can arbitrarily select one according to the monitoring area. For example, the warning sensor 8 uses a passive and / or active infrared sensor or magnet sensor, an ultrasonic wave or a microwave that has a high canceling effect on a small animal or the like and has a good resistance to noise such as ambient light and draft air. Examples include an ultrasonic sensor and a microwave sensor to detect, a gas leak sensor to detect gas leak, a heat detection type to detect a fire, a smoke detection type, and / or an ion detection type fire sensor and a heat ray sensor. Moreover, as the warning sensor 8, even if it is a sensor that is normally provided at a position independent of the monitoring camera, such as a glass breakage sensor, a shutter sensor, a vibration switch, and / or a safe sensor, It is possible to use the sensor by providing a function of performing communication between the sensors. When the monitoring camera 1 detects a change in the monitoring area based on the video and detects an abnormal situation by the various warning sensors 8, the monitoring camera 1 sends the video and audio to the monitoring server 2 and the portable terminal 3. By transmitting the data, it is possible to realize a very high precision and powerful monitoring system.

  The monitoring server 2 stores the video obtained by being imaged by the monitoring camera 1 and the acquired audio together with index information indicating the shooting location and the shooting time. At this time, when a plurality of monitoring areas are monitored by installing a plurality of monitoring cameras 1 in the same address, the monitoring server 2 together with a device number uniquely assigned to each monitoring camera 1 The video and audio are stored. In addition, the monitoring server 2 performs predetermined password processing when storing video and audio, and requests input of a set password when viewing the video and audio, so that an image and video by an unauthorized third party can be obtained. Audio viewing can be prevented. The password here is information uniquely given to each user, and is determined when the security system provider or the user sets the usage contract for the security system. The monitoring server 2 enables viewing of video and audio stored by a third party only when a permission notification signal described later is received from the mobile terminal 3.

  The mobile terminal 3 is a terminal possessed by a user who has made a use contract for the security system, such as a mobile phone or a personal digital assistant (PDA), and is interactively communicated with the surveillance camera 1. It is possible to perform. When there is a change in the monitoring area, the portable terminal 3 receives the video and audio of the monitoring area transmitted from the monitoring camera 1 and displays the video via a monitor which is a predetermined display means. The sound is output through a speaker which is a predetermined output means. As a reception form of such video and audio, a format directly downloaded from the surveillance camera 1 or a so-called e-mail attached file format can be adopted. Further, the mobile terminal 3 may receive video and audio at the same time as notification of occurrence of an abnormal situation, or may receive only when the user selects. Furthermore, the mobile terminal 3 transmits the voice that the user has uttered to the monitoring camera 1. Furthermore, the portable terminal 3 can also transmit an instruction signal for outputting the sound recorded in advance by the monitoring camera 1 through the speaker 7. At this time, when a plurality of sounds are recorded in the surveillance camera 1 in advance, the mobile terminal 3 can also select a sound to be output via the speaker 7 in accordance with a user operation.

  Based on the video and audio received from the monitoring camera 1 via the mobile terminal 3, the user can determine the necessity of the reporting operation after confirming the situation of the situation. That is, based on the video and audio received from the surveillance camera 1 via the mobile terminal 3, the user can determine whether or not the person is familiar, whether or not a disaster such as a fire has actually occurred. Judgment can be made. If the mobile terminal 3 determines that a report is necessary as a result of the user watching the video and audio in the monitoring area in this way, the mobile terminal 3 may determine whether the report is necessary. It is possible to report directly to public organizations such as fire-fighting organizations, private organizations such as security companies, and other notification destinations in the vicinity of the monitoring area as necessary. In addition, the mobile terminal 3 sends a permission notification signal indicating that the viewing of video and audio stored in the monitoring server 2 by a third party is permitted according to a user's operation. It transmits to the server 4.

  The notification central management server 4 is provided in a centralized notification management center of a public organization such as a police organization and / or a fire fighting organization or a private organization such as a security company. The report central management server 4 accesses the monitoring server 2 based on the report from the user via the mobile terminal 3 and the password included in the permission notification signal received from the mobile terminal 3, By entering the password, the staff of the institution can view the video and audio related to the report. Therefore, in the security system, it is possible to make an objective and professional judgment in order to appropriately cope with the situation by viewing a video and audio by a professional staff member. In addition, the message central management server 4 can request dispatch to an instruction for directly dispatching personnel from the report central management center, or an engine closer to the monitoring area or an engine equipped with facilities.

  The terminal 5 is provided at a report destination arbitrarily set by the user other than the report central management server 4 such as a personal computer, a mobile phone, or a portable information terminal. As the report destination, an individual and / or an organization existing in the vicinity of the monitoring area is desirable in order to deal with the situation at an early stage. When the terminal 5 changes the monitoring area, the terminal 5 receives the monitoring area video and audio transmitted from the monitoring camera 1 under the control of the monitoring server 2 in accordance with a user instruction. The video is displayed via a predetermined monitor and the sound is output via a speaker. As such a video and audio reception mode, a format directly downloaded from the surveillance camera 1, a so-called e-mail attached file format, and the like can be adopted as in the portable terminal 3. Based on the video and audio received from the monitoring camera 1 via the terminal 5, the report destination confirms the status of the situation, and then takes measures such as rushing to the monitoring area.

  In such a security system, a security sensor 8 is attached to the surveillance camera 1 and a change in the surveillance area is detected based on an image obtained by imaging, and only when an abnormal situation is detected by the security sensor 8. Since video and audio are transmitted to the monitoring server 2 and the mobile terminal 3, it is possible to realize a monitoring system that is extremely accurate and powerful than expected compared to the case where a monitoring camera and a warning sensor are provided alone. it can.

  In addition, in this security system, since the user is intervened in the on-site situation judgment, it is possible to grasp the situation concerning the report most accurately, and the video and audio are uniquely possessed by the user. Since it is transmitted to the mobile terminal 3, it is possible to reliably avoid a situation in which privacy is infringed.

  In particular, in this security system, not only the video in the monitoring area but also the audio can be transmitted from the monitoring camera 1 to the mobile terminal 3 so that the situation at the site can be reliably grasped, and the mobile terminal 3 can transmit audio to the surveillance camera 1 and output it through the speaker 7, or output pre-recorded audio through the speaker 7, so that the user is at a remote place. Even in such cases, it is possible to take immediate threatening measures, greatly improve the deterrent's ability to deter behavior, and actively contribute to preventing the user from causing damage. can do.

  At this time, in the security system, bidirectional communication is performed between the monitoring camera 1 and the mobile terminal 3 using the mobile terminal 3 that can be connected to the network, so that the video line is used as a communication line. Therefore, it is not necessary to use two lines for voice, and bidirectional communication can be performed using only one line. Therefore, it is extremely effective for multipoint monitoring. Also, in the security system, by using the mobile terminal 3, it is unlikely that the line will be disconnected before the surveillance camera 1 is destroyed, so the information collecting ability can be improved. In particular, in a security system, the use of a mobile phone as the mobile terminal 3 lowers the connection cost for sending and receiving video and audio due to the recent reduction in packet charges. Convenience can be provided.

  In addition, in this security system, not only public organizations such as police agencies and / or fire fighting organizations and private organizations such as security companies, but also notification destinations such as the vicinity of monitoring areas arbitrarily set by users, By providing information, appropriate measures can be taken quickly and damage can be prevented. That is, in the security system, there are cases where the alarm sound is not heard in the vicinity or the alarm light installed outdoors is not conspicuous only by threatening an illegal intruder with a predetermined alarm sound. When an abnormal situation occurs, it can be expected that an appropriate measure can be quickly taken by notifying a nearby reporting destination. This is because neighboring people are not intended to arrest illegal intruders and the like, and the fact that they perform mutual monitoring is highly effective in suppressing the actions of illegal intruders. Such a security system can be a good material for acquiring a plurality of customers even for a system provider.

  In this way, in the security system, the video and audio of the surveillance area are transmitted to the user, and after waiting for the judgment, it is sent to a public or private organization, and if necessary, to a predetermined reporting destination. It is possible to monitor with high accuracy without infringing on the privacy of the user by reporting to and permitting the viewing of video and audio, and the initial investigation of the police agency and the initial digestion activity of the fire fighting agency, etc. It is possible to accurately assist in the professional handling of In the security system, the monitoring camera 1 constantly monitors the monitoring area, and when there is a change in the monitoring area, immediately notifies the user of the occurrence of an abnormal situation via the mobile terminal 3. Therefore, it is possible to obtain an extremely high crime prevention / disaster prevention effect without losing the timing of coping. Of course, it can be said that such a security system is extremely effective not only for intrusion and disasters, but also as an emergency notification means for elderly people living alone.

  The present invention is not limited to the embodiment described above. For example, in the above-described embodiment, it is assumed that the monitoring server 2 is accessed from the notification central management server 4 that has received the notification from the user via the portable terminal 3 and the permission notification signal from the portable terminal 3. As described above, the present invention may transmit video and audio from the monitoring server 2 that has received the permission notification signal from the portable terminal 3 to the notification central management server 4 and the terminal 5.

  In the embodiment described above, the microphone 6 and the speaker 7 are attached to the monitoring camera 1 so as to be integrated. However, the present invention can acquire the sound in the monitoring area. In addition, if it is possible to output sound to the monitoring area, the monitoring camera 1, the microphone 6 and the speaker 7 do not need to be integrated.

  Furthermore, the present invention can also assign a fixed IP (Internet Protocol) address to the surveillance camera. Thereby, in this invention, it becomes possible to give a server function to a surveillance camera. That is, in the present invention, it is possible to perform an operation of actively watching video and audio from a mobile terminal. This means that a plurality of portable terminals can be provided and simultaneous monitoring from a plurality of connection destinations can be performed. In addition, in the present invention, by providing a server function to the surveillance camera, it is possible to easily realize a mechanism that requires processing on the server side such as moving image distribution, update of a program by remote operation, etc. Maintenance is also easy. In the present invention, by using a so-called Linux (Linux) as an OS (Operating System) of the surveillance camera having such a server function, it can be realized at a relatively low cost, and it is also considered to be incorporated. It becomes possible to construct a highly scalable and convenient system.

  Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.

It is a figure explaining the structure of the security system shown as embodiment of this invention.
