FIELD: video surveillance technologies.
SUBSTANCE: method includes surveillance of state of object, by surveillance blocks, each of which includes camera and microphone, low-frequency signals received from each block are converted to high-frequency television modulated signals, which are inputted into unified cable main, formed by coaxial television cable, along which received independent signals are sent to input of control panel, in form of television receiver or computer, provided with extension board, allowing to receive and display images of several surveillance objects concurrently, while power is fed along coaxial chamber of television cable main.
EFFECT: higher efficiency.
