POE switches in the network video monitoring application
With the sustained and rapid development of our country‘s economy, safety technology market got fully development. All kinds of technology applied in safety facilities, to maintain social order, protect the safety of people‘s life and property has played an important role. Among them, the most widely used, the development is a video monitoring system for a longer time. In this paper, in the video monitoring system of intelligent building, for example, mainly expounds the working principle of video monitoring system, emphasizes the POE in network monitoring, the application of this new technology also includes engineering design method and the problems needing attention.
