METHOD FOR MULTICHANNEL VIDEO-AUDIO SURVEILLANCE AND SYSTEM FOR REALIZATION OF SAID METHOD (VARIANTS) Russian patent published in 2005 - IPC

Abstract RU 2250503 C1

FIELD: video surveillance.

SUBSTANCE: method includes video surveillance of controlled object state, while into television cable main of object high-frequency television modulated signal is sent, while to receive signal concerning state of S objects, each of which includes group of N video surveillance blocks, including camera and microphone, video-audio signals from each group of N video surveillance blocks are combined along low frequency, received complex video signal is converted from each group of N video surveillance blocks into high-frequency television modulated signal and it is synchronized with unified cable main - coaxial television cable, in arbitrary groups combination, via which received independent S signals are sent to input of visualization and/or recording systems.

EFFECT: higher efficiency.
