The Design And Implementation Of The Audio And Video Surveillance Platform

Along with the development of information technology,video surveillance products were developed from initial analog to digital, and then network video surveillance solutions were provided, it is increasingly important for daily life of the people. This thesis studies the design and implementation of audio and video monitoring platform, the main work is as follows.First of all, introduces the features of video monitoring and background,it present that what kind of technology is required for this software product, such as communication protocol, data transmission protocol, database management technology and so on.Then, the overall framework of audio and video surveillance platform design is given, it is C/S model (Client/Service), the client is the graphical operation interface for users. The server is compose of configure sever, device adapter server, streamer media server, storage sever. And gives a detailed description of the important modules, and signal flow chart analysis. Admin sever is in charge of log in/log out, conversation, sever management, viewing video and playback, task management, system state information; Device adapter sever sends command to front-end device, and get the feedback from sever and then pass to client; Streamer media server receives stream of video and audio form front-end device, and distribute to others clients; Storage sever record all the log and video/audio, it is independently running in the storage sever.At the end, the paper introduces the application in the actual scene, and verified the main function of the video surveillance center.In this thesis, considering actually application, we designed a video surveillance center. It is compose of the front end device, local surveillance center and multistage center, the main function is record, playback, storage for the video and audio, etc.
