1. Description of campus network video surveillance system:
　　In recent years, the frequent occurrence of campus theft has made teachers and students in many schools feel the need to strengthen public security monitoring, especially during the breaks and when there is no one at school.
　　This network intelligent monitoring system program is specially designed for campus security. The technology and equipment used in the program have been rigorously verified, and are maturely applied in various fields, which are advanced at home and abroad. This plan uses each building or each area as a sub-system, forming a huge campus network monitoring system through the existing campus local area network.
　　2. The composition of the campus network video surveillance system:
　　The campus network video surveillance system uses the existing campus network to monitor the entire campus' teaching buildings, laboratory buildings, student dormitories, student cafeterias, main entrances and exits of the campus, and important public places.
　　Install infrared integrated color cameras at the entrances and exits of teaching buildings and laboratory buildings and corridors; install infrared integrated color cameras at the entrances and exits of student dormitories, school cafeteria warehouses and restaurants, and install cloud-mounted infrared integrated cameras at campus gates and public places Color camera. (Remarks: The infrared camera is used mainly for safety at night). The video surveillance images of all cameras will be transmitted to the office machines of the school leaders (including the principal’s office, security office, etc.) through the established campus network on the campus. As long as the school leaders enter the correct user name and password, they can view up to 16 channels. The real-time image of the camera, and the image can be controlled, recorded and played back. It can realize real-time monitoring of point-to-multipoint, multipoint-to-multipoint, and multipoint-to-point.
　　3. Features of campus network video surveillance system:
　　Utilize the existing campus network resources and at the same time use the surplus optical fiber of the campus network for network data transmission to realize all the functions of the campus network video surveillance system. The plan is implemented in a decentralized and then centralized manner, that is, each building is used as an independent sub-system, and one or two network digital monitoring hosts monitor the entire building. When the control center cannot be located, a virtual network is designed The monitoring center connects an ordinary computer to any node in the campus network to make it a network monitoring center, and you can freely view any picture of any sub-system in the system. In this way, before the construction of the second phase of the project, the use of a virtual network monitoring alarm center can also achieve the purpose of comprehensive monitoring. A true network monitoring and alarm center is constructed after each independent sub-system is built, and it can be built without the condition that it is not mature. It will not have any impact on the whole system, so that existing resources can be used flexibly to construct a single sub-system. Finally, when conditions are ripe, build a general monitoring center. The monitoring system of each building can be used alone or combined organically to realize all-round, all-weather network monitoring, so as to realize multi-point-to-point and point-to-multipoint real-time monitoring.
