随着Internet/Intranet网络技术与多媒体技术的发展，多媒体远程监控系统呈现出数字化、智能化等新特点。在此介绍了基于IP组播的多媒体远程监控系统WebEye的设计思想、系统构成以及部分实现技术。利用IP组播技术，监控的视音频、现场告警与控制信号可在不增加带宽的情形下传至网络所及的每一个感兴趣的监控节点，使得监控信息可以从监控中心释放出来。该系统具有良好的可扩展性和实用性。

With developing of Internet/Intranet and multimedia technology, multimedia surveillance systems have been shown to be digital and intelligent. this paper gives a detailed introduction on design policy, system architecture as well as realization methods of WebEye, an IP Multicast based multimedia surveillance system designed by us.Due to utilizing Internet infrastructure service IP multicast Technology, monitor signaling can be fanned out from center without additional bandwidth as Real time AV streaming, warning and control signaling can reach every network node which is interested in a particular transmission simply "turn in" by subscribing to the multicast group in question. WebEye has a good expansibility and practicability.
