摘要
提出了一个基于SIP协议的嵌入式视频监控系统。它的监控端采用嵌入式Linux设备,并且使用SIP协议同监控中心进行通信。通过SIP协议,监控中心能够开启和关闭视频监控,调整监控端的监控参数如亮度、对比度和色调等。监控端还能实现自主监控,当发现监控对象发生意外情况,能及时向监控中心报警。SIP的应用不仅拓展了视频监控系统的物理范围,也提高了监控的智能性。
An embedded video monitoring system based on session initiation protocol （SIP） was proposed. Its monitoring device equipped with embedded Linux system communicates with the monitoring center in the way of SIP. Through SIP the monitoring center can open and close video monitoring, adjust monitoring parameters on the monitoring terminal, e.g. brightness, contrast and tone. Furthermore, the monitoring terminal can carry out automatic monitoring. When the monitored objects change unexpectedly, the monitoring terminal will send an alarm to the monitoring center. SIP application in video monitoring system not only extends its physical scope, but also promotes monitoring intelligence.
