Claims (4)

In a monitoring system having a monitoring camera that captures a preset monitoring area and a monitoring server connected to a plurality of the monitoring cameras,
The surveillance camera is
When arbitrary position control information is input, a camera unit that switches from the monitoring area to an area based on the position control information and shoots,
An image analysis unit for detecting an abnormal region by analyzing image data captured by the camera unit;
An abnormality monitoring position calculation unit that calculates position control information for causing the camera unit to photograph the abnormal region detected by the image analysis unit and outputs the position control information to the camera unit and the monitoring server;
The monitoring server is
Using the position control information output from the abnormality monitoring position calculation unit of the monitoring camera that has detected the abnormal area, a blind spot that is generated when the monitoring camera switches shooting from the monitoring area to the abnormal area set in advance. A blind spot area calculation unit for calculating an area;
A surveillance camera that captures the blind spot area is selected from the surveillance cameras other than the surveillance camera that has detected the abnormal area, and the surveillance area and the blind spot area that are preset for the selected surveillance camera are photographed simultaneously. A monitoring system comprising: a blind spot monitoring position calculation unit that calculates position control information for output to the camera unit of the selected monitoring camera.   When the blind spot area calculation unit of the monitoring server calculates a plurality of blind spot areas, the blind spot monitoring position calculation unit selects one monitoring camera for each of the calculated blind spot areas, and the previously set for each of the monitoring cameras 2. The monitoring system according to claim 1, wherein position control information for simultaneously photographing the monitoring area and the blind spot area is calculated. An image analysis unit that detects abnormal areas by analyzing image data captured by the camera;
A monitoring server that calculates position control information for photographing the abnormal region detected by the image analysis unit and calculates a blind spot region that is generated by switching the region photographed by the camera from the monitoring region to the abnormal region. An abnormality monitoring position calculation unit that transmits the position control information to
When the position control information is input from the abnormality monitoring position calculation unit, shooting is switched from the monitoring area to the abnormality area, and when the position control information is input from the monitoring server, the monitoring area and the blind spot area A surveillance camera comprising a camera unit that controls to take a picture. When the first monitoring camera that captures the predetermined monitoring area detects an abnormal area, the first monitoring camera uses the position control information output from the first monitoring camera to move the first monitoring camera from the monitoring area. A blind spot area calculation unit for calculating a blind spot area generated by switching the shooting to the abnormal area;
The second surveillance camera that captures the blind spot area is selected from other surveillance cameras except the first surveillance camera, and the second surveillance camera selects the surveillance area and blind spot area of the first camera. A monitoring server provided with a blind spot monitoring position calculation unit that calculates position control information for photographing at the same time and outputs the position control information to the second monitoring camera.
