The camera setting of the monitoring camera 1 is performed from the setting PC 6. The elevator 8 moves up and down according to the floor information input by the elevator controller 7. The elevator controller 7 is connected to the network 2. The elevator controller 7 notifies the monitoring camera 1, the monitoring PC 3, and the network recorder 4 of the elevator information (input floor information etc.) via the network 2. The elevator controller 7 and the monitoring camera 1, the monitoring PC 3, and the network recorder 4 may be directly connected without the network 2.

  FIG. 2 is a block diagram illustrating the configuration of the surveillance camera 1 according to the first embodiment. 9 is a photographing unit, 10 is an image signal processing unit, 11 is a video output unit, 12 is a CPU (control unit), 13 is a memory, 14 is a power supply control unit, 15 is a turning drive unit, 16 is a control input / output unit, 17 Is an elevator information input unit. The photographing unit 9 obtains an image by photographing a target area to be monitored. An image obtained by the photographing unit 9 is input to the image signal processing unit 10. The image signal processing unit 10 may perform analog / digital conversion on the image, transmit the converted image data to the video output unit 11, and store the converted image data in the memory 13. Also, the image signal processing unit 10 performs object detection processing and motion detection processing on the image, and performs detection of abnormality, detection of an intruder, prediction of the moving direction of the intruder, and the like using the processing, and the information is sent to the CPU 12. To the control input / output unit 16.

The elevator information input unit 17 is connected to the elevator controller 7 of FIG. 1 via the network 2 of FIG. The elevator information input unit 17 receives elevator information from the elevator controller 7 of FIG. Specific examples of elevator information include floor number information input by a user on the elevator, power supply information of the elevator (power ON information, power OFF information), and the like. The elevator information input unit 17 transmits the received elevator information to the CPU (control unit) 12. The elevator information input unit 17 may be directly connected to the elevator controller 7 or may be connected via a device other than the network 2 in FIG.

The memory 13 stores the installation position of the own camera separately from the converted image data. Specific examples of the installation position include an installation floor and whether or not the elevator door can be photographed. The installation position stored in the memory 13 may be information input from the control input / output unit 16 and stored in the memory 13 or may be information stored in advance.

As the memory 13, a rewritable recording / reading medium is used. For example, a semiconductor memory, a hard disk drive, a magneto-optical disk drive, a magnetic tape drive, or the like can be used. In particular, a semiconductor memory is preferable because it can be read at high speed and is small. Further, the memory is preferably configured to be detachable from the monitoring camera 1 like a card type or a removable medium. Further, each monitoring camera 1 may not have the memory 13 but may be configured so that each monitoring camera 1 is used in common by providing a network storage such as a hard disk connected to the network 2.

The CPU 12 determines and implements control of the surveillance camera according to the elevator information input from the elevator information input unit 17 and the installation position of the own camera read from the memory 13. Specific examples of the installation position include an installation floor and whether or not the elevator door can be photographed. Specific examples of monitoring camera control include power supply control and turning control. As the power control, the CPU 12 instructs the power control unit 14 to turn on or turn off the power. As the turning control, the CPU 12 instructs the turning drive unit 15 on the rotation direction, the rotation angle, and the like. The CPU 12 may output the determined control content of the monitoring camera to the control input / output unit 16.

The turning drive unit 15 may operate based on control information input from the control input / output unit 16 separately from the turning control from the CPU 12. The turning drive unit 15 is operated by a motor, and realizes panning and tilting operations of the monitoring camera 1. The control information input from the control input / output unit 16 includes various controls such as a zoom operation and sensitivity switching of the photographing unit 9 in addition to the control of the turning drive unit 15.

  The control input / output unit 16 can also transmit and receive data between networks, exchange information with another monitoring camera 1, and transmit and receive signals for performing linkage operations.

A specific example of the method for determining the control of the monitoring camera by the CPU 12 is shown below.

A specific example of the control information of the monitoring camera when the installation floor of the monitoring camera 1 and the floor information of the elevator information coincide is shown below. The power control is “power ON” or “maintaining the power ON state”. As the turning control, “turning so that the vicinity of the elevator door can be photographed” or “photographing in the vicinity of the elevator door is prioritized”. The pan direction / angle and the tilt direction / angle of the turning operation are stored in the memory 13 so that the vicinity of the elevator door can be photographed, and the CPU 12 may refer to the memory 13. The control information of the monitoring camera may be the above only when the floor information of the elevator information matches and the power information of the elevator is ON. By receiving the elevator information, even in the monitoring cameras installed on different floors, the shooting direction of the monitoring camera can be adjusted ahead of the intruder's progress. Thereby, there is an effect of suppressing the missed shooting of the intruder or the intruding object at the decisive timing.

Next, a specific example of the control information of the monitoring camera when the installation floor of the monitoring camera 1 and the floor information of the elevator information do not match is shown below. It is determined that the camera itself is set at a position unrelated to the direction in which the intruder advances, and the power control is set to “power OFF” or “power saving mode (standby mode)”. The power saving mode is a mode that realizes power saving while turning off the power supply of a part of the blocks instead of turning off the power supply of the entire surveillance camera and enabling quick operation. The turning control is “turning so that the initial setting position can be photographed” or “priority other than photographing near the elevator door”. The panning direction and angle of the turning operation and the tilting direction and angle of the turning operation are stored in the memory 13 so that the initial setting position can be photographed, and the CPU 12 may refer to the memory 13. There is an effect that it is possible to reduce power consumption while suppressing missed shooting of an intruder or an intruding object.

In addition, as a specific example of the control information of the monitoring camera when the power supply information of the elevator is OFF as the elevator information, the specific information of the control information of the monitoring camera when the installation floor of the monitoring camera 1 and the floor information of the elevator information do not match Same as example.

Next, the operation of the surveillance camera system will be described. FIG. 3 is a flowchart showing the overall operation of the surveillance camera system according to the first embodiment.

  In step ST <b> 101, the CPU 12 receives elevator information from the elevator information input unit 17.

  In step ST <b> 102, the CPU 12 reads the installation position of the own camera from the memory 13.

  In step ST103, the CPU 12 determines whether the power supply information of the elevator in the elevator information received in step ST101 is “ON”. If it is not “ON”, the process proceeds to step ST104 to instruct the power supply control unit 14 to “turn off the power”. If it is “ON”, the process proceeds to step ST105 to instruct the power supply control unit 14 to “power ON”.

  In step ST106, the CPU 12 compares the floor information received in step ST101 with the installation position of the own camera read in step ST102. If the floor information of the elevator information is not equal to the installation floor, the process proceeds to step ST107. . If the floor information in the elevator information is equal to the installation floor, the process proceeds to step ST108.

  In step ST107, the CPU 12 instructs the turning drive unit 15 to “turn so that the initial setting position can be photographed”. The CPU 12 reads from the memory 13 the pan direction / angle and the tilt direction / angle of the turning operation that enables the initial setting position to be photographed, and instructs the turning drive unit 15.

  In step ST108, the CPU 12 determines whether or not the installation position of the own camera read in step ST102 is a position where the elevator door can be photographed. If it is not a position where the door can be photographed, the process proceeds to step ST107. If it is a position where the door can be photographed, the process proceeds to step ST109.

  In step ST109, the CPU 12 instructs the turning drive unit 15 to “turn so that the vicinity of the elevator door can be photographed”. The CPU 12 reads from the memory 13 the pan direction / angle and the tilt direction / angle of the turning operation so that the vicinity of the elevator door can be photographed, and instructs the turning drive unit 15. At that time, the CPU 12 may read out the focal length, the zoom, and the like from the memory 13 and instruct the photographing unit 9.

  Note that the determination in step ST103 may be performed after step ST108. Further, step ST108 may not be performed.

  The CPU 12 may determine and implement control of the monitoring camera based on detection information from an infrared sensor, a gate authentication device, or the like instead of the elevator information from the elevator controller.

  In the above description, an example in which the CPU 12 determines and implements control of the surveillance camera according to the elevator information input from the elevator information input unit 17 and the installation position of the own camera read from the memory 13 has been disclosed. The memory 13 may store the installation position of the own camera and the control information of the monitoring camera for each elevator information. CPU12 should just read the control information of the monitoring camera corresponding to elevator information, and should implement power supply control and turning control according to the read control information of the monitoring camera. The turning control information includes a turning position for photographing the elevator door, an initial setting position, and the like. Examples of the turning control information include pan direction and angle, tilt direction and angle, and the like as pan and tilt operation control information. The installation position and turning control information stored in the memory 13 may be information input from the control input / output unit 16 and stored in the memory 13, or may be information stored in advance.

  A specific example of the control information of the monitoring camera for each elevator information stored in the memory 13 is shown in FIG. For example, FIG. 4 shows an example in which the monitoring camera is installed on the second floor and the elevator door can be photographed.

  (1) When the floor information of the elevator information is “2” and the elevator power information is “ON”: the power control of the surveillance camera is “ON” or “maintains the power ON state”. The turning control of the surveillance camera is “photographing the vicinity of the elevator door” or “photographing the vicinity of the elevator door”.

  (2) When the floor information of the elevator information is “2” and the elevator power information is “OFF”: The power control of the surveillance camera is “power OFF” or “power saving mode (standby mode)”. The turning control of the surveillance camera is “turning so that the initial setting position can be photographed” or “priority other than photographing near the elevator door”.

  (3) When the floor information of the elevator information is “other than 2” and the elevator power information is “ON”: The power control of the monitoring camera is “power OFF” or “power saving mode (standby mode)”. The turning control of the surveillance camera is “turning so that the initial setting position can be photographed” or “priority other than photographing near the elevator door”.

  (4) When the floor information of the elevator information is “other than 2” and the elevator power information is “OFF”: The power control of the surveillance camera is “power OFF” or “power saving mode (standby mode)”. The turning control of the surveillance camera is “turning so that the initial setting position can be photographed” or “priority other than photographing near the elevator door”.

Thereby, there is an effect of suppressing the missed shooting of the intruder or the intruding object at the decisive timing. In addition, the power consumption of the surveillance camera set at a position unrelated to the direction in which the intruder travels can be reduced.

Depending on the monitoring importance of the monitoring area in which the detection report has been made, the necessary monitoring area is determined. Depending on the importance of monitoring, the shooting direction of the monitoring camera can be adjusted ahead of the intruder.

  If there is a detection report in a monitoring area with a high monitoring importance level, the monitoring area with any monitoring importance level is set as a necessary monitoring area. Regardless of whether the monitoring area linkage control information of the monitoring cameras installed in all other monitoring areas has a connection part with the monitoring area where the detection report has been made, the power control is “ON” or “power ON” Maintenance of state ". The turning control of the surveillance camera is “photographing the vicinity of the connected part” or “photographing the vicinity of the connected part is prioritized”. It is possible to adjust ahead of the intruder's progress to the monitoring area with high monitoring importance. Thereby, there is an effect of suppressing the missed shooting of the intruder or the intruding object at the decisive timing.

  When there is a detection report in a monitoring area having a monitoring importance level, an area having a connection portion with the monitoring area in which the detection report is present is determined as a necessary monitoring area. The power control of the surveillance camera that can shoot the connected portion is “ON” or “maintains the power ON state”. The turning control of the surveillance camera capable of photographing the connected portion is “photographing the vicinity of the connected portion” or “priority is taken near the connected portion”. On the other hand, the power control of the surveillance camera that cannot shoot the connected portion is “power OFF” or “power saving mode (standby mode)”. The swivel control of the surveillance camera is “turn so that the initial setting position can be photographed” or “priority other than photographing near the connected portion”. When there is no connection with the monitoring area where the detection report has been made, the power control of the monitoring camera is “power OFF” or “power saving mode (standby mode)”. The swivel control of the surveillance camera is “turn so that the initial setting position can be photographed” or “priority other than photographing near the connected portion”. As a result, it is possible to reduce the power consumption and to suppress the taking over of the decisive timing of the intruder or the intruding object.

  If there is a detection report in a monitoring area with a low monitoring importance, the monitoring area with any monitoring importance is not designated as a linked monitoring area. The monitoring area linkage control information of all other monitoring cameras installed in the monitoring area is “power OFF” or “power saving mode (standby mode)” for power control of the monitoring camera. The swivel control of the surveillance camera is “turn so that the initial setting position can be photographed” or “priority other than photographing near the connected portion”.

Next, the operation of the surveillance camera system will be described. FIG. 9 is a flowchart showing the overall operation of the surveillance camera system according to the second embodiment. FIG. 9 explains the case of FIG. 6 as the monitoring area division and the installation location of the monitoring camera, and the case of FIG. 8 as the monitoring area cooperation control information. A case will be described in which there is a detection report by the monitoring camera 22b installed in the monitoring area 3 (adjacent monitoring area).

  In step ST <b> 901, the monitoring camera 22 b installed in the monitoring area 3 that has detected the occurrence of an abnormality and the detection of an intruder notifies the monitoring area cooperation management device of the monitoring information. Conduct detection reports. In the detection report, the identification number of the self-monitoring camera is also notified.

  In step ST902, the monitoring area cooperation management device reads monitoring area cooperation control information corresponding to the detection report received in step ST901 from the memory. Based on the identification number of the monitoring camera received in the detection report, it is determined in which monitoring area the detection has been performed. The monitoring area linkage control information corresponding to the monitoring area for which the detection report has been received is read from the memory.

  In step ST901 to step ST910, the monitoring area cooperation management device performs monitoring area cooperation for each monitoring area based on the monitoring area cooperation control information read in step ST902 in order to perform monitoring in which a plurality of monitoring areas are linked. Notify control information.

In the above description, the monitoring area cooperation control information is stored in the monitoring area cooperation management device, but may be stored in each monitoring camera. In that case, the monitoring area cooperation management device determines in which monitoring area the detection is performed from the identification number of the monitoring camera received in the detection report. What is necessary is just to notify the monitoring camera of the information of the monitoring area in which the detection report was performed from the monitoring area cooperation management apparatus.

  In the above description, the power supply control has been described for controlling the power supply of the surveillance camera. However, when a storage device such as a ring buffer is provided in the surveillance camera, the power supply and activation are controlled together. May be.

  In the above description, power supply control and turning control have been described as monitoring area cooperation control information. However, control such as ISO sensitivity and frame rate of the camera may be performed.

  Note that the second embodiment may be used in combination with the first embodiment.

  According to the second embodiment, the following effects can be obtained. The shooting direction of the surveillance camera can be adjusted ahead of the intruder. Thereby, there is an effect of suppressing the missed shooting of the intruder or the intruding object at the decisive timing. In addition, the power consumption of the surveillance camera set at a position unrelated to the direction in which the intruder travels can be reduced.
