Web Video Monitoring System，long-distantly monitors the dynamics scene of some certain spots through video，so that we can achieve daily administration and react rapidly to unusuality. The system has a far-ranging foreground and society value in many important spots where information is widely transmitted，such as electrics，posts，banks，traffics，shopping malls，uptowns，and so on.
Basing upon the Web Video Monitoring System which consists of computer digital video processing technology，digital video compressing code technology，computer digital video web transmitting technology，and so on，basic principles and basic ways of carrying out are fundamentally discussed around-the-board in this essay.
In Web Video Monitoring System，for convenience to process of a computer，a serial image the video has shot should be processed，namely changing the analog signals into digital signals. As digital sounds and images consist of much data，memory capacity，transmitted ratio and accounting rate which are needed during processing digital sounds and images can’t be supported in the current computer without compressing. Therefore，breakthrough in digital compressing technology leads media communication to computer. Among the basic principle introductions of Web Cam Monitoring System，this essay focus on several basic compressing code ways of image serials.
In the system designing part，the essay emphasizes in video data processing，video data sending and receiving.
For Web Video Monitoring System is widely used in intellectualized uptowns，the essay takes the storied building in Xi’an Construction and Technology University as example，setting out a detailed designing project of Web Video Monitoring System.
