Functional Test of Hanging Fiber Detection and Video Monitor System for Perimeter Security

摘要

Considering the shortcomings of the traditional security technology system, such as poor stability, limited installation environment, high false alarm and missing report rate, this paper proposes a hanging fiber detector and video monitor system for perimeter security based on Michelson Interference Technology, and carries out functional test in the oil terminal of Petrochina Company Limited. In this system, an ordinary single-mode communication optical cable is arranged along the top of the fence in wavy shape. When the intruder climbs or turns over the fence, the system triggers the alarm event and emits an alarm. Then the high-speed dome camera will be controlled to turn and shoot the location of the invasion through the network video recorder and network switch. In the functional test, the system has realized climbing alarm, knocking the wall alarm, multi-point simultaneous intrusion alarm, false alarm learning, broken fiber alarm and other functions, which has better sensitivity, lower false alarm rate and better learning function compared with the products based on Sagnac principle and double MZ principle.
