I. Overview
With the Ministry of Education,  the implementation of projects, the domestic institutions of higher learning are basically built a Gigabit or even 10 Gigabit backbone for the campus network, became the most comprehensive network facilities, one of the most advanced industries. How to make full use of campus network to provide network facilities, offers a variety of applications and services, improve college teaching and management level, as "Xiao Jiaotong" project after the implementation of an important topic.
Network video surveillance technology, as in network technology developed on the basis of a new generation of video surveillance technology, it can not only make full use of campus network bandwidth provided by the exceptional conditions, the construction of low-cost, distributed, the campus network monitoring system, but can also Greatly enhance the monitoring and management of the campus, build a "safe campus, and civilized campus," an important means.
The programme aims to make use of the existing campus network resources, construction of IP-based network transmission of the campus network video surveillance systems to improve the campus technology means the security level to ensure that teachers and students on campus safety, safeguard the normal teaching and living order .
Second, needs analysis
The main campus network monitoring role:
Monitoring the door Kong: Progressive Chujiao Men of the personnel, vehicles for records and statistics to facilitate tracking and enquiries afterwards.
Teaching the District Monitoring: The teaching area of teaching order, and access to the area of teaching staff, logistics for recording and monitoring, through the unexpected events of the video and improve the ability to handle emergencies.
Monitoring living quarters: the living quarters and out of the flow of people, logistics and recorded statistics, the personal protection of students, not against property.
Library monitoring: the flow of people entering and leaving the library, logistics to monitor and record, no one night when the deployment.
Through the monitoring system before the analog network transformation, so that it can easily carry out the entire network management.
DLVS video network management system, including DLVS110EC, DLVS110EF, DLVS120EC, DLVS140EC series network video server, DLVS111D, DLVS141D, DLVS182D series network video decoder and video management software, users can build a complete network video monitoring solutions.
Third, network
Campus network monitoring system from the structural division may generally be divided into three, from the bottom-up include:
Mun Kong, junctions, living quarters, teaching, library and other monitoring points
Ge Jiaoqu Monitoring Center: responsible for monitoring the district's management and monitoring points
School Monitoring Center: Ge Jiaoqu responsible for the monitoring points and centralized management scheduling
Traditional campus is monitoring the use of simulation solutions, namely, the use of simulated camera images collected on the spot, through video-or long-distance transmission Guangduan Ji carried out near the control center through simulation matrix, DVR and other devices to signal extraction , Switching lines, image storage, on the monitor. This solution is the main problem:
Ge Jiaoqu monitoring system between the scattered, independent, multi-level network can not meet under the centralized management structure
A waste of transmission resources, cabling, construction costs are high
Based on analog video transmission vulnerable to interference, it is difficult to guarantee the quality of video transmission
Can not be achieved remote monitoring and scheduling functions
A network of video surveillance technology, we can solve the existing analog control over the issue, thereby greatly increasing the efficiency of colleges and universities monitoring and management level, but also greatly improving the overall investment monitoring system of the economy.
