This paper designs a monitoring system based on distributed network. Web camera collection video data for the system and compression, then send the data to the remote PC host, the hose analysis image frame for face recognition and gait recognition to detect the abnormal body, then control camera haeundae for monitoring. The system makes use of real-time transmission protocol and real-time control protocol to complete the distributed video acquisition and centralized processing on network, which provide a highly efficient feasibility and low cost solutions, the system has very good real-time and interactive performance.
