FIELD: TV equipment, security systems. SUBSTANCE: device has TV detectors 8 which firing causes output of "Warning" signals by memory units 23 for address and target. "warning" signals are used by video signal commutation units 29 for connection through video signal commutator 20 between correction amplifiers 9 and video displays 5 and video recorders 2. Automatic search of intruders is made by digital azimuth scanning units 32 together with automatic units 27. Source data for scanning algorithm are output to automatic unit 27 from data input unit 28. EFFECT: 24-hour automatic search and detection of intruders, on-line alternation of device structure and operation algorithms. 4 cl, 34 dwg
