The invention discloses a wetland park oriented security precaution integrated system and a method. The system comprises an intelligent video and electronic patrol linkage subsystem, an anti-theft alarm subsystem, a parking garage management subsystem, an access control subsystem, a fire alarm subsystem, a voice and broadcast subsystem and the like. Subsystem integration adopts a Web services technology to uniformly encapsulate definition information, behavior and work flows as well as construct a service architecture-oriented security precaution integrated system; data transmission is based on a VOX multi-service optical transmission platform with a ring network self-healing function, the VOX bandwidth is dynamically allocated according to requirements and high-grade security services are allocated to redundant bandwidth in proportion of 1:1 to ensure high reliability and high availability of the services; patrol is in linkage with a video analysis tripwire alarm module, and an image post-processing mixed dynamic and static threshold is adopted, thus effectively solving the problem of video analysis object detection, and reducing the working strength of monitoring staff, the false alarm rate and missed out rate of the system.
