The present invention is a surveillance camera capable of wide area surveillance and automatic local surveillance and tracking of subjects. The subjects outside the area may include information stored in the memory unit when detecting a subject in the moving area from the wide field of view image data of the wide area monitoring; It operates the up, down, left, right drive unit and zoom magnification and focal driver to record magnified image data at narrow angle of view of the local surveillance and store the video tape recorder (VCR) and DVR (DigitalVideoRecoder) recorder. By storing the images of surveillance cameras in the media, it is possible to search a wider range of video information by acquiring wide range surveillance of the subject and local surveillance data when searching recorded video data. An apparatus and method are provided.

1A is an exemplary diagram of a subject tracking surveillance camera using a conventional sensor.

FIG. 1A is a diagram for exemplarily illustrating an installation state of an object tracking photographing apparatus of FIG. 3 of a “subject tracking photographing apparatus and method” disclosed in Korean Laid-Open Patent Publication No. 1999-0086438.

In case of subject tracking of the existing surveillance camera of FIG. It is a device that tracks and photographs the subject by calculating the location memory information when detecting the sensor by using the principle of operation of the sensor by using a detector such as a passive intruder.

If the above method is applied, it should be installed at the door of the location where the detector is to be tracked by remembering the position of the door sensor by tracking the position of the door sensor. Or, if an open store without a door itself or a detector cannot be installed due to the nature of the monitoring site, it is difficult to install the system itself, and it becomes difficult to construct an existing equipment system such as financial sectors and public offices where internal monitoring is important.

Figure 1b is a diagram illustrating a subject tracking using a conventional human body sensor.

1B is a representative view of a diagram of a method for “automatically detecting a motion of a human body” published in Korean Laid-Open Patent Publication No. 2002-0084910.

Even when using a conventional camera with a built-in PASSIVE INFRARED DETECTOR, the subject can be automatically tracked using the internal space human body sensor without the door sensor instead of the position memory tracking device by the door sensor of the existing equipment of 1a. The module can be used to track the subject, but due to the detector characteristics of the PASSIVE INFRARED DETECTOR

Figure 2 is a detailed view of the detection area of the human body sensor (PASSIVE INFRARED DETECTOR).

In places with many subject movements, the system configuration itself is difficult and difficult.

In order to utilize the functions of the existing COMBI Dome Camera and SpeedDomeCamera, there must be a person who can operate the surveillance and camera controller (Pan / Tilt Zoom controller). If you do not look at the screen, subject monitoring becomes difficult and the equipment configuration itself becomes complicated.

Existing Fixed Camera When the Zoom Camera is installed for the purpose of wide area monitoring, it is possible to monitor a large area, but it is impossible to accurately photograph the subject because the screen of the subject is displayed small on the monitor. If the fixed surveillance camera is installed for the purpose of local surveillance, it is possible to monitor the enlarged image of the subject, but it is impossible to photograph outside the surveillance area.

In order to solve the above-mentioned problem of the conventional surveillance camera, the present invention does not use a sensor used for motion detection and stores the movement area setting of the motion processor in the surveillance camera and the position memory and zoom magnification of the surveillance camera in a memory. The purpose of the present invention is to provide an apparatus and method for photographing a subject tracking surveillance camera capable of automatically switching between glory and regional surveillance.

For example, when the present invention is applied to important facilities in financial institutions and government offices, the monitoring center or the reception desk can be used to predict the direction of the customer by using the motion process, and then set the movement area. In this case, the focus data is stored in the memory unit, and the wide area monitoring is performed in the area outside the detection area, and the local monitoring is performed in the detection area. By using the present invention to obtain detailed and detailed data when storing the recording screen in a storage medium such as equipment video tape recording (VCR) or DVR (DIGITAL VIDEO RECORDER), the existing CCTV (Closed Capable of monitoring only one method of wide area surveillance or local surveillance, which are disadvantages of Circuit Television) and DVR (Digital Video Recorder) It can help you build a more advanced surveillance equipment only replacement of the present invention.
