In order to utilize the functions of the existing COMBI Dome Camera and Speed Dome Camera, there must be a person who can operate the surveillance and camera controller (Pan / Tilt Zoom controller). Or monitoring the monitor screen, subject monitoring becomes difficult and the device configuration itself becomes complicated.

In addition, when a fixed camera or a zoom camera is installed for the purpose of wide area monitoring, a wide area can be monitored, but the shooting screen of the subject is displayed small on the monitor so that the correct subject is displayed. In the case that the photographing of the camera is impossible and the fixed surveillance camera is installed for the purpose of local surveillance, the enlarged video surveillance of the subject is possible, but the photographing outside the surveillance area is impossible, and thus, a plurality of surveillance cameras need to be additionally installed.

The present invention solves the problems of the conventional surveillance camera described above, without using a sensor (SENSOR) used for motion detection, the motion area setting of the motion processor in the surveillance camera and the position memory and zoom magnification of the surveillance camera are stored in the memory. It is an object of the present invention to provide a photographing apparatus of a subject tracking surveillance camera that can be stored and automatically switch between wide-area and local surveillance.

For example, when the present invention is applied to important facilities in financial institutions and government offices, the monitoring desk or the reception desk can be used for intensive monitoring. Double speed and focus data are stored in the memory unit to perform wide area monitoring in areas outside the detection area, and local area monitoring in the detection area. It captures all the shots and saves the shot screen to a storage device such as video tape recorder (VCR) or DVR (DIGITAL VIDEO RECORDER) to get more detailed and detailed data. According to the present invention, it is possible to construct more advanced equipment only by replacing the surveillance camera of the present invention that it is possible to monitor only one method of wide area surveillance or local surveillance, which is a disadvantage in the conventional closed circuit television (CCTV) and digital video recorder (DVR). Can be.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

As shown in FIG. 3, when there is a movement of the moving subject in the motion setting area during the wide-area monitoring using the image input unit 10, the motion processor 20 detects the movement and is stored in the memory unit 30. Area monitoring data is calculated by the microprocessor unit 40 from the location memory and the zoom magnification information, that is, the information of the area monitoring area, and the upper and lower left and right driving units 53 of the driving unit 50 are driven to control the position of the surveillance camera. The lens driving unit 57 is driven to switch to local surveillance. When the moving subject is not detected in the moving area during the preset local monitoring execution time, the first step, that is, the wide area monitoring area, is automatically switched. In the setting of the wide area monitoring area and the area monitoring area, the position information and the zoom magnification of the surveillance camera are stored in the memory unit 30 by the remote operation unit 70 using the screen of the character generator 60.

As shown in FIG. 4, a block area is set in units of cells on an OSD (on screen display) using a motion processor with a motion detection circuit, and a wide area is detected until a subject movement is detected in the motion area in a wide area monitoring format. Since only the surveillance type can be executed, it can be used in places with many moving subjects. In addition, as shown in Fig. 5A, before the counselor's work desk, i.e., the point in time at which the movement of the subject is stopped is calculated in advance, the movement area is set, and then the position memory and zoom magnification of the local surveillance are stored in the memory unit. In addition, as shown in Figure 5b, when the visited customer is detected in the motion detection area is switched to the local surveillance photographing style. As shown in FIG. 5C by setting an execution time or an area monitoring motion region stored in the memory unit, when the subject is not detected in the area monitoring shooting time and the movement area, it is determined according to the information stored in the memory unit (position memory, zoom magnification). Operate the drive unit to automatically switch to the first step of the wide-area photography mode.
