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. |

Method comprises subtracting reference and current images, breaking the image series to be processed into fragments, and converting the characteristic features of the images into signals. The signals from one of the images are recorded as reference ones and are compared, e.g., by subtracting, with corresponding current signals, and, after the threshold processing, the difference signals obtained are converted into the binary signals for control of spatial filtration . As a result, the fragments of the current image, for which the control signals exceed the threshold, are transmitted, whereas the fragments, for which the signals are equal or less than the threshold value, are suppressed. |
