SIP-based embedded video monitoring system
|
Abstract:
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.
