LOW-FRAME-RATE VIDEO SURVEILLANCE SYSTEM FOR CONTROL OVER LONG SECURITY BOUNDARIES

摘要

FIELD: physics.;SUBSTANCE: system consists of a central control unit and many groups of geographically remote addressable video cameras linked to the central control unit using a specially designed information transfer tract with using fibre-optic lines. The video cameras are designed to operate in a low-frame mode with the formation and transmission of pre-alarm, alarm and post-alarm video information to the central control unit for the purpose of detailed viewing of the alarm situation for reliable identification of the intruder.;EFFECT: improvement of noise immunity when using the system for long distances or when placing it on the ground under the influence of powerful electromagnetic interference.;2 cl, 3 dwg
