ABSTRACT
The monitoring system of the video is an important part in the technological system of safe precaution. The application of this kind of system is developed extremely fast in our country at present, and the market competition is fierce. General, video control system made up of four parts mainly: Picture information gathering; the signal is transmitted; Switch over and control; showing and recording equipment remotely. With computer high-speed development of technology, a whole system towards Digitalization, Networking, Integration's direction is developed. This thesis takes environmental monitoring as an example mainly, expound the fact that the general video supervises operation principle and design method of the monitoring system, and introduce the newest development trend of this kind of technology.
