With the increase of campus violence and emergencies in recent years, the construction of network video surveillance systems in primary and secondary schools has been used to improve campus management and security, which has become a new security requirement for primary and secondary schools. Using Unitek's Neitway network video surveillance management system to realize the overall solution of network video surveillance system for primary and secondary schools, make full use of the existing campus network, provide high-speed image transmission in the simplest way, and complete the key areas of the campus in the monitoring room. Real-time monitoring of school playgrounds, teaching classrooms, and surrounding environment to improve campus security work efficiency; at the same time, the Academic Affairs Office can learn about classroom teaching in real time through the network video monitoring system of primary and secondary schools.
Design Analysis of Network Video Surveillance System in Primary and Middle Schools
Since the design specifications of network video surveillance systems in primary and secondary schools have been introduced one after another, in addition to the requirements of the design specifications of security systems, it is also based on the design specifications of network video surveillance systems for primary and secondary schools.
The biggest feature of the Neitway network video surveillance management system is that it can be monitored from any time, from anywhere, to any site through a computer network. It does not need to be laid like a traditional analog digital surveillance system. A large number of cables save the user's upfront investment. Compared with traditional analog devices, the network video surveillance system has strong scalability. For example, if you add one channel of video surveillance, the analog device may need to add a hard disk recorder, and network video surveillance only needs to add an IP address. Realization; therefore, the scalability of network video surveillance is unmatched by traditional analog video, and more applications can be extended through remote networks.
Topology map of network video surveillance system for primary and secondary schools:
The network video surveillance system of the whole primary and secondary schools is mainly composed of three parts: the front-end system, the transmission system and the monitoring management control system.
Design of front-end system for network video surveillance system in primary and middle schools
In the construction of network video surveillance system for primary and secondary schools, in order to effectively maintain campus order and student safety, according to different environments and monitoring requirements, different network cameras are configured to meet the optimal solution of image capture points, while also taking into account the price of customers. Affordability.
1. The flow of people at the gates of the school is complicated, and the construction of the school gates is very prone to traffic accidents. Some socially unscrupulous youths gather at the entrance of the school. In the design of network video surveillance system in primary and secondary schools, the intelligent network high-speed ball NND-7385X is installed in the internal and external areas of the school gate, and the activities of personnel and vehicles within 30M near the entrance and exit are monitored. When disputes and accidents occur, remote control is possible. The ball machine monitors the local area and collects the video through video recording. At the same time, the network dome camera NNH-708 is installed near the guard room to monitor the entry and exit of personnel.
2. In the network video surveillance system of primary and secondary schools, the administrative building, the teaching building entrance and exit and the main passage corridor are also the key areas for monitoring. For the case of multiple entrances and exits, it is necessary to install the network infrared integrated camera NNF-7082 at each entrance and exit to monitor the entry and exit personnel. Happening;
3. Set up monitoring points in school walls and carports. The network video surveillance system in the primary and secondary schools installs the network infrared camera NNF-7082 according to the distance and area to monitor the real-time and video, ensuring the night monitoring effect and ensuring the safety of public and personal property;
4. In the playground area of ​​the campus, there are many sports activities and more personnel activities. The intelligent network high-speed ball NND-7385X is used to monitor the panorama of the playground. When disputes and accidents occur, the ball machine can be remotely controlled to monitor the local area. Afterwards, a video recording was conducted for forensic investigation.
5. Use the wide-angle network dome camera NNH-708 in the classroom to cover all the seats in the classroom. Usually, you can monitor the daily teaching classroom situation. When monitoring as a test center, you can access the dedicated online invigilation system through the network to isolate the monitoring equipment permissions of the classroom to meet the national and local requirements for the examination room monitoring. At the same time, it is also possible to conduct open class guidance and distance education through the Internet.
6. Install the network dome camera NNH-708 in the laboratory and computer room of the school to monitor the activities and equipment of the laboratory and the equipment room.
Primary and secondary school network video surveillance transmission system
The network video surveillance system is based on IP network design. The main data transmission medium is Ethernet twisted pair. The network video surveillance system of the primary and secondary schools can be well integrated into the existing campus local area network. For remote monitoring points, the use of fiber-optic network cameras can reduce the cost of using optical transceivers for other systems and reduce the number of faults caused by intermediate devices such as photoelectric converters or optical transceivers.
Design of Network Video Surveillance Management Control System for Primary and Middle Schools
For different scales, our company has developed a corresponding network video surveillance management software platform for primary and secondary schools:
