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.
