video screen comparators

400a and 400b and the controller 500 are configured.

First, referring to FIG. 2, the first CCTV 100 according to a preferred embodiment of the present invention is a means for photographing an image of a human body or an object that is close to the command of a controller, and has a constant distance from a location where CCTV is installed. It takes a still image and a video from the proximity sensor 110 for detecting a human body or an object approaching within.

Here, the proximity sensor 110 is selected from any one of the far-infrared sensor or the distance sensor installed in the CCTV angle to detect the far-infrared radiation generated by the human body in proximity to the installed CCTV area or both the far-infrared sensor and the distance sensor Can be mounted on the front of the CCTV angle.

Referring to FIG. 2, the second CCTV 200 according to an exemplary embodiment of the present invention is a means for capturing an image when a human body approaching a command is different from a natural person by a command of a controller. It is installed side by side, and captures still images and videos from the image detection sensor 210 that detects the same state of masking intensity and different from the appearance of a natural person approaching within a certain distance from the CCTV installed position.

Also, in the present invention, the speed dome camera may be replaced instead of the first and

second CCTVs

100 and 200.

Referring to FIG. 2, the first and second

video signal decoders

If the still image screen size of the human body is a still image screen size value (P2, P3) that is suddenly larger than the preset still image screen size value (P1), the first CCTV 100 is intermittently photographed to capture still images and videos continuously. The second CCTV 200 stops when the human image (or the exposed face) of the natural person and the other still image screen, that is, the masking intensity, are compared with the second image screen comparator 400b. The video and video are continuously taken and stored in the external hard drive 600 to be immediately transmitted to the control center 700. And when the CCTV is operating through the speaker 510 to guide the broadcast and the cheating is caught through the buzzer 520 to generate a warning sound.

In this case, an interface means is determined to store the image screen data photographed on the external hard disk 600. The transmission of the image screen data to the control center 700 is a conventional technology such as a wired / wireless communication method and an internet method. This applies.

In addition, the controller 500, when there is no information compared in the first / second

video screen comparator

400a, 400b with respect to the video screen shot from the first / second CCTV (100, 200), the first The second CCTV (100,200) can be controlled to suspend video recording.

This function is to consider the buffer capacity of the external hard 600 due to unnecessary video shooting when there is no movement such as a human body, an object, and a masking intensity close to the CCTV installation area.

As described above, in the CCTV system having the image screen comparing unit according to the embodiment of the present invention, the still image screen size captured by the first CCTV 100 through the first image screen comparing unit 400a is set to the memory unit 410. The values P2 and P3 that are enlarged larger than the image screen size value P1 and the still image screen photographed by the second CCTV 200 through the second image screen comparing unit 400b are stored in the memory unit 410. To compare and judge whether the still image screen of the different masking intensity is different from the third CCTV (200a) or n-th CCTV (200n) driving in conjunction with the first / second CCTV (100,200) to the accessor cheating By recording still images and videos in three dimensions and storing them in the external hard drive 600 to be transmitted to the control center 700, it is possible to prevent violent crimes such as masking robbery as well as to cut off CCTV and CCTV cables, and to thoroughly monitor and control Unique features that can There.
