This paper constructs a kind of distributed long-distance fiber per imeter security monitoring system with video linkage function.Distributed fiber-opt ic vibration sensor technology based on dual Mach-Zehnder interferometer (DMZI) architecture is us ed in the system to monitor all kinds of real-time disturbances and intrusions on the cable.The system also uses signal processing technology so that it could locate and identify intrusion events,and emit different warning signals according to the different intrusion events.Meanwhile,the video surveill anc e system begins to record the disturbance behavior for further processing.Positi o ning accuracy and false alarm rate of the system are measured by experiment.The results show that this system can ef fectively achieve the linkage function with the video,the positioning accuracy reaches 91%,and t he false alarm rate is maintained at less than 3times a day in normal weather conditions.In this pape r,new distributed fiber sensing technology,traditional video surveillance technology and advanced signa l intelligent identification technology are fused,so a hybrid intelligent p erimeter security monitoring network is formed.
