一、System character：
　　·Allow many directors to use this system at the same time make they can know the all situation at the prison。
　　·Any monitoring spot can use multimedia computer or control keyboard to operate。
　　·The system carries out centralized management and dispersed control. All main controllers are set in the main control room. The leaders can monitor in their offices。
　　·The system uses pinhole camera and covert high-sensitivity pick-up audio monitor the site。
　　二、System structure:
　　The front end cameras part
　　Complete the acquisition and processing of images and sounds, etc. Then send these data to monitoring center through the network monitoring center。
　　The monitoring center
　　The monitoring center is the core part of the whole system. It is the system management center of data management, data storage and data backup. The main control make up of a comprehensive monitoring system integrated structure with remote control center and front-end monitoring node through the network。
　　The remote control center
　　It performs remote video monitoring and system control through the network. It is made up of video switch, control system and computer operating system. The remote control center can remotely see the front end video image. When a leader wants to see the specific situation of some place, it will export video images through the network。
　　三、System composition:
　　Public monitoring
　　It will monitor the activities of prisoners by using our integrated monitoring system and installing a certain number of cameras in the public. It can clearly and accurately record behaviors of prisoners on these occasions, and can conveniently and effectively know the actual situation of events when has emergency。
　　Cell monitoring
　　We need real-time monitor their activities for some highly dangerous prisoners to prevent accidents and ensure the safety of others and prisons. It will can real-time record by using the monitoring system and installing cameras in the cells. It also can monitor the cells through the remote control center and realize real-time。
　　Alarm talkback system
　　Alarm talkback subsystem is used in prison when the prisoners escape, suicide, blows or other emergencies. It can directly report to the police or main control center in order to timely disposition。
　　Peripheral guard alarm system
　　The prison peripheral guard alarm system can realize the following functions: when someone tries to climb the wall or fence prison, the flash alarm in security center will make the acousto-optic alarm, the LCD display the alarm area, and alarm disk around the center of security guard screen. The peripheral guard screen in security center also displays alarming area so that the security personnel alarm timely。
