SECURITY TELEVISION SYSTEM Russian patent published in 2012 - IPC G08B13/196 

FIELD: information technology.

SUBSTANCE: system is equipped with two memory modules, two analysis and recognition units, one having a function for analysing and comparing records from the first frame to the last, and the other having a function for analysing and comparing records from the last frame to the first, and a second video monitor, where each television camera is connected through a data network to the corresponding analysis and recognition unit which is connected to the corresponding memory module and the video monitor. Television cameras are arranged such that they can be simultaneously rotated in the horizontal plane by a rotary drive. Optical axes of the television cameras lies on a straight line and are directed oppositely. Motion detectors lie on the security perimeter. The output of each motion detector is connected to the corresponding pulse former, whose output is connected to the input of an OR element, whose output is connected to control inputs of the television cameras and the rotary drive. Efficiency of the security television system lies in elimination of blind spots inside the perimeter of the secured object, which prevents intrusion of the facility.

EFFECT: high efficiency of inspecting a secure territory on the perimeter and avoiding intrusion, achieved due to that the security television system comprises two television cameras connected through a data network to a video monitor and motion detectors connected to a signalling unit.
