Description

  The present invention relates to a security device that transmits an alarm to a monitoring center connected to a network when an abnormality in a monitoring area is detected, and more particularly to a security device that can control the shielding of a lens of a monitoring camera.

  Security devices that send an alarm to a monitoring center connected to a network when an abnormality is detected in the monitoring area are generally equipped with a monitoring camera for monitoring the monitoring area that is the security area to be monitored Known.

  A conventional surveillance camera in such a security device always shoots an object to be monitored, and always records an image or transmits it to a monitoring center as necessary. However, since such a security device always shoots at places and times when it is not desired to shoot, privacy infringement becomes a problem. In view of this, there has been disclosed a technique for transmitting a video captured by a monitoring camera to a monitoring apparatus only when there is an abnormality (see, for example, Patent Document 1). Moreover, only when there is a nurse call from a subject to be photographed, the surveillance camera is directed to the subject to be photographed, and at other times, the surveillance camera is directed to a direction in which no one can photograph (for example, Patent Document 2). reference).

  However, in the technique of Patent Document 1, since the surveillance camera is photographing even if the photographed image is not actually transmitted and privacy is not infringed, the person in the photographing region Cannot confirm on the spot that privacy has not been violated. For this reason, there is a problem that a person in the imaging region has anxiety and tension that the surveillance camera is constantly monitoring.

Also in the technique of Patent Document 2, there is a case where the presence of the monitoring camera itself makes the monitoring subject feel nervous.
Further, the technique of Patent Document 2 cannot be realized without using a pan / tilt camera having a photographing direction preset function, and means for avoiding privacy infringement has been demanded for other types of surveillance cameras.

  The present invention has been made in view of the above, and avoids infringement of privacy to a person in the shooting area of the surveillance camera, and gives a sense of security by clearly not infringing on privacy. It is an object of the present invention to provide a security device that can perform such operations.

In order to solve the above-described problems and achieve the object , the invention according to claim 1 is a timer setting for setting a shielding signal transmission time for transmitting a shielding signal instructing shielding of a lens of a monitoring camera that images a monitoring region.

Exemplary embodiments of a security device according to the present invention will be explained below in detail with reference to the accompanying drawings.
(First embodiment)
First, a first embodiment will be described with reference to the accompanying drawings. The security device according to the first embodiment switches the current security status by inputting the security status, and controls the shielding or release of the lens of the surveillance camera in accordance with the switching of the current security status. . FIG. 1 is a block diagram showing an example of the configuration of the security device according to the first embodiment of the present invention. The security device 100 according to the present embodiment includes a security status input unit 101, a message output unit 102, an alarm transmission unit 103, a trigger signal transmission unit 104, a security status switching unit 105, and a security status storage unit 106. And the lens shielding part 107.

  The security state input unit 101 is connected to a display input device (not shown) such as a liquid crystal touch panel, and inputs an event signal by pressing a security button and a security release button displayed on the screen of the display input device, Based on the input event signal, it is determined whether the security state is security or security release. Specifically, since a security event signal is emitted from the display input device when the security button is pressed, the security status input unit 101 receives the security event signal and sends the security signal to the security status switching unit 105. To do. On the other hand, when the security release button is pressed, a security release event signal is issued from the display input device, so the security state input unit 101 receives the security release event signal and sends the security release signal to the security state switching unit 105. It is supposed to be sent out. In this embodiment, the security button and the security release button are separately displayed on the display input device, and the security state is switched by selecting and pressing the button corresponding to the security state to be switched. One button may be displayed on the display input device, and the switching of the security state may be input by such a single button. Moreover, you may comprise so that a guard state may be switched by methods other than button press, such as switching by setting time.

  The guard state storage unit 106 stores the current guard state of the guard area. This security status indicates the current security status of the security area. If the security status is in the security status, the security mode is set to the security status. If the security status is not in the security status, the security status is set to the security release mode. Are set respectively.

  Here, the security mode refers to a state in which, when the security device receives a detection signal issued when an abnormality such as a fire is detected, an alarm notifying the abnormality is transmitted to a monitoring center connected to the network. The security release mode refers to a state where the security device does not transmit an alarm notifying the abnormality to the monitoring center even when the security device receives the detection signal. When a detection signal generated when a fire is detected or a signal generated by operating an emergency button is received, an alarm is transmitted to the monitoring center regardless of the security mode or the security release mode.

  The security state switching unit 105 constitutes a security state switching unit in the present invention, and switches the security state to the security mode or the security release mode. Specifically, the guard state switching unit 105 sets the guard state set in the guard storage unit 106 when the guard signal is received from the guard state input unit 101 from the guard mode to the guard release mode, and triggers. Processing to instruct the signal transmission unit 104 to block the lens is performed. When the security release signal is received from the security status input unit 101, the security status set in the security storage unit 106 is set from the security release mode to the security mode, and the process of instructing the release of the lens shielding is performed.

  Here, the instruction to shield the lens refers to an instruction indicating that the lens should be shielded with respect to the trigger signal transmission unit 104, and the instruction to release the lens shielding refers to the trigger signal transmission unit 104. An instruction indicating that the lens should be unshielded.

  The alarm transmission unit 103 transmits an alarm to a remote monitoring center connected via a network when an alarm request signal is input. The message output unit 102 outputs a message such as an error message to the display input device.

  The trigger signal transmission unit 104 constitutes trigger signal transmission means in the present invention. When the trigger signal transmission unit 104 receives an instruction to shield the lens of the monitoring camera from the security state switching unit 105, the trigger signal transmission unit 104 transmits a shielding signal to the lens shielding unit 107. When receiving an instruction to cancel the shielding of the lens, a non-shielding signal is transmitted to the lens shielding unit 107.

  Here, the shielding signal means a signal indicating that the lens should be shielded with respect to the lens shielding portion 107, and the non-shielding signal means that the lens shielding with respect to the lens shielding portion 107 should be released. The signal which shows.

  The lens shielding unit 107 constitutes a shielding unit in the present invention. The lens shielding unit 107 shields the lens 201 of the monitoring camera 200 when the shielding signal is received from the trigger signal transmission unit 104, and the camera 200 when the non-shielding signal is received from the trigger signal transmission unit 104. The lens 201 is unshielded. The monitoring camera 200 has a lens 201. The specific operation of shielding and non-shielding the lens will be described later.

  FIG. 2A is a perspective view of the monitoring camera 2 including the lens shielding unit 107 according to the present embodiment. FIG. 2B is a plan view of the monitoring camera 2 including the lens shielding unit 107 according to the present embodiment. The surveillance camera 2 includes a lens 2a, a shutter 2b, and a main body 2c.

  The monitoring camera 2 receives the shielding signal transmitted from the trigger transmission unit 104 by the main body unit 2c and controls the shutter 2b to close. By closing the shutter 2b, the lens 2a is shielded, and the monitoring area 2 Cannot shoot (when blocked). The monitoring camera 2 receives the non-shielding signal transmitted from the trigger transmission unit 104 by the main body 2c, controls the shutter 2b to open, and opens the shutter 2b, thereby releasing the shielding of the lens 2a. The surveillance area can be photographed (when not shielded).

  Next, the lens shielding control process according to the present embodiment configured as described above will be described. FIG. 3 is a flowchart showing a procedure of lens shielding control processing according to the present embodiment.

  First, when a security button or a security release button displayed on a display device (not shown) is pressed by the operator, the security state input unit 101 receives an event corresponding to each button from the display device, and the security button When an event is received, a security signal is transmitted to the security state switching unit 105, and when a security release button event is received, a security release signal is transmitted to the security state switching unit 105.

  Upon receiving a security signal or a security release signal from the security status input unit 101, the security status switching unit 105 acquires the current security status from the security status storage unit 106 (step S3001), and the acquired current security status is the security mode. Or security release mode is determined (step S3002).

  When the security state switching unit 105 determines that the current security state is the security mode (step S3002: security mode), the button pressed by the operator from the input type from the security state input unit 101 Is a security button or a security release button (step S3003). That is, when the security state switching unit 105 receives a security signal from the security state input unit 101, the security state switching unit 105 determines that the security button has been pressed, and when receiving a security release signal from the security state input unit 101, the security state switching unit 105 It is determined that the release button has been pressed.

  When the security state switching unit 105 determines that the security release button has been pressed (step S3003: security release), the current security state is switched from the security mode to the security release mode (step S3004), and the security state storage is performed. The current security state stored in the unit 106 is changed from the security mode to the security release mode. Next, the security state switching unit 105 sends a shielding instruction to the trigger signal transmission unit 104 (step S3005). Upon receiving the shielding instruction from the security state switching unit 105, the trigger signal transmission unit 104 transmits a shielding signal indicating that the lens of the monitoring camera is to be closed to the lens shielding unit 107 (step S3006). When the shielding unit 107 receives the shielding signal from the trigger signal transmission unit 104, the lens shielding unit 107 closes the shutter 2b of the monitoring camera, thereby blocking the lens of the monitoring camera, that is, the photographing disabled state (step S3007).

  If it is determined in step S3003 that the pressed button is a security button (step S3003: security), the processing from steps S3004 to S3007, that is, security status switching processing, shielding signal transmission processing, and lens The process ends without performing the shielding process. This is because the current security state is the security mode based on the determination in step S3002, and the shutter 2b of the surveillance camera is already in the open state. This is because, in order to continue, it is necessary to keep the shutter in the open state and maintain the photographing enabled state by the surveillance camera.

  In the determination of the current security state in step S3002, if the security switching processing unit 105 determines that the current security state is the security release mode (step S3002: security release mode), the security state is the same as in step S3003. It is determined from the input type from the input unit 101 whether the button pressed by the operator is a security button or a security release button (step S3008). When the security state switching unit 105 determines that the security button has been pressed (step S3008: security), the current security state is switched from the security release mode to the security mode (step S3009), and the security state storage unit 106 Is changed from the security release mode to the security mode.

  Next, the security state switching unit 105 sends a non-shielding instruction to the trigger signal transmission unit 104 (step S3010). The trigger signal transmission unit 104 that has received the non-shielding instruction from the security state switching unit 105 transmits a non-shielding signal indicating that the lens of the monitoring camera is to be opened to the lens shielding unit 107 (step S3011). When the non-shielding signal is received, the lens shielding unit 107 opens the shutter 2b of the surveillance camera, thereby making the surveillance camera lens non-shielded, that is, ready for photographing (step S3012).

  On the other hand, if it is determined in step S3008 that the pressed button is a security release button (step S3008: security release), the processing from step S3009 to S3012, that is, the security state switching process, transmission of the shielding signal The process ends without performing the process and the lens shielding process. This is because the current security state is the security release mode and the shutter 2b of the surveillance camera is in the closed state based on the determination in step S3002, but the shutter is used to avoid the privacy infringement of persons existing in the surveillance area. This is because it is necessary to keep the photographing state of the surveillance camera in the closed state.

  Thus, in the present embodiment, when the current security state is switched from the security mode to the security release mode, the person in the monitoring area is not photographed by shielding the lens of the monitoring camera. Since the surveillance camera lens is hidden, it is possible to give a sense of security to the person in the surveillance area by clearly indicating that the surveillance camera is not photographing. Conventionally, since there is a problem such as invasion of privacy, a surveillance camera can be installed in a place where it could not be installed, so that more advanced monitoring can be performed.

  Also, when the current security state is switched from the security release mode to the security mode, it is possible to shoot with the surveillance camera by releasing the shielding of the surveillance camera lens, so in the situation where it is not necessary to consider privacy infringement It is possible to grasp the situation in detail.

(Third embodiment)
A third embodiment will be described with reference to the accompanying drawings. The security device according to the first embodiment releases the shielding of the lens of the surveillance camera when the non-shielding signal is transmitted. However, in the third embodiment, an abnormality is detected in the security area. In this case, the shielding of the lens of the surveillance camera is released. FIG. 25 is a block diagram illustrating an example of a configuration of a security device according to the third embodiment of the present invention. The security device 2500 according to the present embodiment includes a security status input unit 101, a message output unit 102, an alarm transmission unit 103, a trigger signal transmission unit 104, a security status switching unit 105, and a security status storage unit 106. The lens shielding unit 107, the abnormality detection unit 2501, and various sensors 2510a to 2510n. Here, the security state input unit 101, the message output unit 102, the alarm transmission unit 103, the trigger signal transmission unit 104, the security state switching unit 105, the security state storage unit 106, and the lens shielding unit 107 are the same as those in the first embodiment. The description is omitted because it is similar.

  As various sensors 2510a to 2510n, a sensor that outputs a detection signal when a fire is detected by being installed on a ceiling or the like in a security area, or a detection signal that is output when a window glass is broken by being installed on a window glass or the like is output. A sensor or the like that outputs a detection signal when it is installed on an important object such as a safe and detects a destructive action or a take-away action is applicable. The various sensors in the present embodiment do not include sensors (for example, human body detection sensors) whose alarm is not transmitted to the monitoring center even if a detection signal is output when the current security state is the security release mode. And In this case, even if a human body is detected, it is not actually in an abnormal state (for example, the sensor may detect an employee who has entered the company). This is because it is not appropriate to cancel the shielding of the lens.

  The abnormality detection unit 2501 constitutes detection means in the present invention. The abnormality detection unit 2501 receives detection signals from the various sensors 2510 a to 2510 n and outputs an alarm request signal to the alarm transmission unit 103.

  The lens shielding control process according to the present embodiment configured as described above will be described. FIG. 26 is a flowchart illustrating a procedure of lens shielding control processing according to the present embodiment.

  First, the abnormality detection unit 2501 transmits an abnormality detection signal to the trigger signal transmission unit 104 when receiving detection signals from the various sensors 2510a to 2510n. (Step S26001). When receiving an abnormality detection signal from the abnormality detection unit 2501, the trigger signal transmission unit 104 acquires the current security state from the security state storage unit 106 (step S26002), and the acquired current security state is the security mode or the security release mode. Is determined (step S26003).

  When the trigger signal transmission unit 104 determines that the current security state is the security release mode (step S26003: security release mode), the trigger signal transmission unit 104 transmits a non-shielding signal to the lens shielding unit 107 (step S26004). ). The lens shielding unit 107 that has received the shielding signal from the trigger signal transmission unit 104 opens the shutter 2b of the monitoring camera, thereby putting the lens of the monitoring camera into a non-shielded state, that is, a photographing enabled state (step S26005).

  If it is determined in step S26003 that the current security state is the security mode (step S26003: security mode), the processes of steps S26004 and S26005, that is, the non-shielding signal transmission process and the lens shielding cancellation process are performed. Quit without This is because the current security state is the security mode based on the determination in step S26003, and the lens shutter 2b of the surveillance camera has already been opened, so that it is not necessary to perform a lens shielding process or the like. This is because it is necessary to keep the shutter 2b in the open state and maintain the photographing enabled state by the surveillance camera in order to continue the monitoring.

  In this way, when various sensors detect an abnormality, even if the current security state is in the security release mode, it is possible to shoot with the surveillance camera by releasing the shielding of the surveillance camera lens, thereby avoiding privacy infringement. However, it is possible to grasp the situation in detail in the event of an abnormality that requires monitoring.

(Fourth embodiment)
A fourth embodiment will be described with reference to the accompanying drawings. The security device according to the first embodiment releases the shielding of the lens of the surveillance camera when a non-shielding signal is transmitted. In the fourth embodiment, the emergency button is pressed in the security area. In this case, the shield of the surveillance camera lens is released. FIG. 27 is a block diagram showing an example of the configuration of a security device according to the fourth embodiment of the present invention. The security device 2700 according to the present embodiment includes a security status input unit 101, a message output unit 102, an alarm transmission unit 103, a trigger signal transmission unit 104, a security status switching unit 105, and a security status storage unit 106. The lens shielding unit 107, the emergency detection unit 2701, and emergency buttons 2710a to 2710n. Here, the security state input unit 101, the message output unit 102, the alarm transmission unit 103, the trigger signal transmission unit 104, the security state switching unit 105, the security state storage unit 106, and the lens shielding unit 107 are the same as those in the first embodiment. The description is omitted because it is similar.

  The emergency buttons 2710a to 2710n are push buttons or pendant-type wireless push buttons installed on the wall surface of the security area, and output an emergency signal when the button press is detected. In addition, according to the situation of an installation place, you may select and use arbitrary things from the existing emergency push button or the switch operated in order to notify an emergency.

  The lens shielding control process according to the present embodiment configured as described above will be described. FIG. 28 is a flowchart illustrating a procedure of lens shielding control processing according to the present embodiment.

  First, when the emergency button 2710a to 2710n is operated for reporting by the operator, the emergency detection unit 2701 detects that the emergency button 2710a to 2710n is pressed, and the emergency signal is sent to the trigger signal transmission unit 104. A time signal is transmitted (step S28001). When receiving the emergency signal from the emergency detection unit 2701, the trigger signal transmission unit 104 acquires the current security status from the security status storage unit 106 (step S28002), and whether the current security status is the security mode or the security release mode. Is determined (step S28003).

  When the trigger signal transmission unit 104 determines that the current security state is the security release mode (step S28003: security release mode), the trigger signal transmission unit 104 opens the lens of the monitoring camera with respect to the lens shielding unit 107. A non-shielding signal indicating the effect is transmitted (step S28004). The lens shielding unit 107 that has received the non-shielding signal from the trigger signal transmission unit 104 opens the shutter 2b of the surveillance camera, thereby making the lens of the surveillance camera non-shielded, that is, ready for photographing (step S28005).

  If it is determined in step S28003 that the current security state is the security mode (step S28003: security mode), the processes in steps S28004 and S28005, that is, the non-shielding signal transmission process and the lens shielding cancellation process are performed. Quit without This is because the current security state is the security mode according to the determination in step S28003, and the shutter 2b of the lens of the surveillance camera is already in an open state. This is because in order to continue monitoring of the monitoring area, it is necessary to keep the shutter 2b in an open state and maintain a photographing enabled state by the monitoring camera.

  In this way, when it is detected that the emergency button has been operated for reporting, even if the current security state is in the security release mode, the surveillance camera lens can be unshielded so that the surveillance camera can take a picture. Therefore, while avoiding privacy infringement, it is possible to grasp the situation in detail at the time of pressing the emergency button that needs to be monitored.

(Fifth embodiment)
A fifth embodiment will be described with reference to the accompanying drawings. The security device according to the first embodiment shields the lens of the surveillance camera when the shielding signal is transmitted. In the fifth embodiment, the guard device transmits the shielding signal transmission time set by the timer setting unit. In such a case, a shielding signal is transmitted to shield the surveillance camera lens. FIG. 29 is a block diagram showing an example of the configuration of a security device according to the fifth embodiment of the present invention. The security device 2900 according to the present embodiment includes a security status input unit 101, a message output unit 102, an alarm transmission unit 103, a trigger signal transmission unit 104, a security status switching unit 105, and a security status storage unit 106. The lens shielding unit 107 and the timer setting unit 2901 are included. Here, the security state input unit 101, the message output unit 102, the alarm transmission unit 103, the trigger signal transmission unit 104, the security state switching unit 105, the security state storage unit 106, and the lens shielding unit 107 are the same as those in the first embodiment. Since it is the same, description is abbreviate | omitted.

  The timer setting unit 2901 constitutes timer setting means in the present invention. The timer setting unit 2901 sets a non-shielding signal transmission time or a shielding signal transmission time.

  The non-shielding signal transmission time is a time for transmitting a non-shielding signal that is set by the timer setting unit 2901 of the security device and instructing the release of the shielding of the lens of the surveillance camera. For example, by setting the non-shielding signal transmission time to “20:00”, the shielding of the monitoring camera lens is released at 8:00 pm, and the monitoring camera can be imaged.

  The shielding signal transmission time is a time for transmitting a shielding signal that is set by the timer setting unit 2901 of the security device and instructing shielding of the lens of the surveillance camera. For example, by setting the shielding signal transmission time to “8:00”, the surveillance camera lens is shielded at 8:00 am, and the surveillance camera cannot be captured by the surveillance camera.

  The lens shielding control process according to the present embodiment configured as described above will be described. FIG. 30 is a flowchart illustrating a procedure of lens shielding control processing according to the present embodiment.

  First, when the operator inputs the non-shielding signal transmission time, the timer setting unit 2901 sets the non-shielding signal transmission time (step S30001). The trigger signal transmission unit 104 determines whether or not it is the non-shielding signal transmission time for which the current time is set (step S30002). When the trigger signal transmission unit 104 determines that the current time is not the set non-shielded signal transmission time (step S30002: No), the trigger signal transmission unit 104 is the non-shielded signal transmission time until the current time becomes the non-shielded signal transmission time. Or not is repeated (step S30002). When the trigger signal transmission unit 104 determines that the current time is the non-shielding signal transmission time (step S30002: Yes), the trigger signal transmission unit 104 acquires the current security state from the security state storage unit 106 (step S30003), and the current security. It is determined whether the state is the security mode or the security release mode (step S30004).

  When the trigger signal transmission unit 104 determines that the current security state is the security release mode (step S30004: security release mode), the trigger signal transmission unit 104 opens the lens of the monitoring camera with respect to the lens shielding unit 107. A non-shielding signal indicating the effect is transmitted (step S30005). When the lens shielding unit 107 receives the non-shielding signal from the trigger signal transmission unit 104, the lens shielding unit 107 opens the shutter 2b of the monitoring camera to make the lens of the monitoring camera non-shielded, that is, ready for photographing (step S30006).

  If it is determined in step S30004 that the current security state is the security mode (step S30004: security mode), the processing in steps S30005 and S30006, that is, the non-shielding signal transmission processing and the lens shielding cancellation processing are performed. Quit without This is because the current security state is the security mode according to the determination in step S30004, and the shutter 2b of the lens of the surveillance camera is already in an open state, so there is no need to perform a lens shielding release process or the like. This is because in order to continue monitoring the monitoring area, it is necessary to keep the shutter 2b in an open state and maintain a photographing enabled state by the monitoring camera.

  Next, when the operator inputs the shielding signal transmission time, the timer setting unit 2901 sets the shielding signal transmission time (step S30007). The trigger signal transmission unit 104 determines whether or not the current time is the set shielding signal transmission time (step S30008). If the trigger signal transmission unit 104 determines that the current time is not the set shielding signal transmission time (step S30008: No), whether or not the current time is the shielding signal transmission time until the current time becomes the shielding signal transmission time. The determination is repeated (step S30008).

  When the trigger signal transmission unit 104 determines that the current time is the shielding signal transmission time (step S30008: Yes), the trigger signal transmission unit 104 acquires the current security state from the security state storage unit 106 (step S30009), It is determined whether the security state is the security mode or the security release mode (step S30010). When the trigger signal transmission unit 104 determines that the current security state is the security mode (step S30010: security mode), the trigger signal transmission unit 104 shields the lens shielding unit 107 from opening the surveillance camera lens. A signal is transmitted (step S30011). When the shielding unit 107 receives the shielding signal from the trigger signal transmission unit 104, the lens shielding unit 107 closes the shutter 2b of the monitoring camera, thereby blocking the lens of the monitoring camera, that is, the photographing disabled state (step S30012).

  If it is determined in step S30010 that the current security state is the security release mode (step S30010: security release mode), the processes in steps S30011 and S30012, that is, the shielding signal transmission process and the lens shielding process are not performed. To finish. This is because the current security state is the security release mode based on the determination in step S30010, and the lens shutter 2b of the surveillance camera is already closed, so there is no need to perform further lens shielding processing, etc. This is because in order to continue monitoring the area, it is necessary to keep the shutter 2b in the closed state and maintain a state incapable of photographing by the monitoring camera.

  As described above, in this embodiment, when the non-shielding signal transmission time set by the timer setting unit is reached, the surveillance camera can be photographed by releasing the shielding of the surveillance camera lens. Until then, it is possible to grasp the situation in detail during the guard period while avoiding privacy infringement.

  In addition, when the shielding signal transmission time set by the timer setting unit is reached, it is possible to avoid infringement of privacy because the person in the surveillance area is not photographed by shielding the lens of the surveillance camera. Since the surveillance camera lens is hidden, it is possible to give a sense of security by clearly indicating that privacy is not infringed. For example, it is not possible to shoot a surveillance camera during work hours at a company, etc., and it is possible to avoid privacy infringement and to give a sense of security by clearly indicating that privacy has not been infringed, and visitors to the company It is possible to prevent leakage of confidential information such as products under development in business partners (meetings with business partners) and R & D departments.

  As described above, the security device according to the present invention is suitable for use in a security system using a surveillance camera, particularly for installation of a surveillance camera in a place where privacy violation must be avoided.
