An IP video monitoring system is mainly consists of wireless spy camera, storer, server and software. The wireless spy cameras are usually dissipated in various places, but the storer and server need to be managed integratedly. A ste of video management system (VMS) can offer unified visits of integrated real-time video recording and management, which are from different manufacturers. While the new wireless spy camera adapts the MPEG-4 and H.264 video compression standard, which can offer HD video streams and DVd between 1M and 12M bps. This provides much convinence for the strengthen of recording device and the integrated management and daily maintenance. Because the video contents of wireless spy cameras can send to different parts and people according to different needs, which is convinent to monitor and unified management. VMS can be used for recording, streaming media and multiplex video content. It can translate the different origins and different formats of videos to the common standarded formats, it can also be used for offering recording and replaying service. It can also be used to replay the different terminals. Pixels, kpbs video content. The large scale of deployment of architecture will involve thousands different positions of wireless spy cameras. Most security policy require the video to be kept for one week or one month, and few security policies require that the video contents to be kept for a year on longer. The reservation time of videos is directly connected with the costs of management and maintenance.
