支持无线网络的实时视频监控系统设计

Design of real-time video surveillance system Supporting wireless-network

为了解决有线网络视频监控的布线问题和工作人员的移动化监控问题,设计并实现了一种支持IP摄像头、DVR、3G手机作为视频数据采集前端,兼容H.264和MPEG4等编码标准和支持PC和3G手机进行客户端监看的实时视频监控系统,该系统实现视频的采集、压缩、传输、解码、显示、控制、录像、事件通知、电子地图等功能,该系统支持前端采集设备的多流输出和高并发访问,适应了3G手机的带宽,提高了服务器使用效率,达到了利用手机进行移动视频监控的目的。

To solve the wiring problem of wire-network video surveillance and the removable suiveillance problem of worker, a type of real-time video surveillance system that support IP camera/DVR/3G smartphone at the front-end of video data capture and support H.264/MPEG4 as the encoding method and support PC/3G smartphone at the client of video monitoring is designed and imple- mented. The system implements the function of video capture, compression, transmission, decoding, display, control, record, event no- tify, electronic map. The system supports multiple output streams and high concurrent access of the front-end capturing device,adapts to 3G network＇s bandwidth, improves the server＇s using efficiency and achieves the desired goal that realizes mobile video surveil- lance by smart phone.
