With the development of education in China, the scale of the school has been expanding, the density of students has been concentrated, and the degree of school openness and logistics services have become higher and higher. Improving school district security protection and responding to sudden group incidents and reducing school violence have become key tasks. Optical Network Video's security surveillance campus solution is aimed at the research of video surveillance systems in smart campuses, which can effectively improve campus science management and security.

 

Project Introduction

The Affiliated Secondary School of NUA is affiliated to Nanjing University of the Arts. It is located in Nanjing University of the Arts. It was founded in 1958, with 25,000 square meters and 20 classes. It has complete modern teaching and living facilities. The video surveillance system of the optical network has been stationed on the campus one after another, becoming an important technical means for the campus to do a good job in campus security.

Background Needs

Due to the increasing number of people and vehicles entering and leaving the campus, in order to ensure the safety and safety of students' personal and property, video surveillance systems, vehicle management systems, alarm management systems have emerged. Combined with the comprehensive supervision platform of the smart campus, the comprehensive and comprehensive supervision of the entire campus is realized.the comprehensive problem of security systems has become a serious injury in the process of use. As more and more subsystems are built, each subsystem operates independently and controls, and the information island phenomenon is serious, and the problem gradually emerges.

Campus Security Monitoring Solution

The scheme system combines intelligent management methods, uses intelligent analysis technology, and simultaneously uses video surveillance system, vehicle management system, access control management system and alarm management system to comprehensively manage people, vehicles and objects inside and outside the campus, and change passive monitoring to take the initiative. Defense, the central management platform can also integrate other security systems in colleges and universities to achieve information sharing, unified linkage, and improve the overall security management level of the campus.

The transmission architecture is the "neural network" of the network monitoring system. To ensure the bandwidth requirements of image transmission and real-time storage, the network video surveillance system should use a dedicated network, with gigabit fiber as the backbone, 100M access, and reserve for the future. Mega expansion capability. The monitoring center sets up the core switch to aggregate all video data of each area and the sub-control center.

Topology architecture

A star topology network is adapted to implement a two-layer architecture, and simple topology enhances system stability.

Switching capacity configuration

The access layer adopts a Gigabit backplane, and a large cache PoE power supply switch to set up the highest configuration switching capacity link

Link medium

The access layer links are all based on the principle of proximity, using CAT6 network cable connection and transmission, and then connected to each unit aggregation switch through the uplink port of each power supply switch, reducing multi-level series, convenient for the entire system after completion Management and maintenance.

Device configuration

The access layer adopts Optical Network Video (ONV) commercial series 8/24 ports gigabit PoE fiber switch as the backbone, and 8/18/28 ports gigabit security PoE power supply switch access.

Program Advantage

Transmission monitoring features

For the high-definition video surveillance system, the video stream enters the PoE switch from IP camera, and the traffic direction is from the bottom to the top. The data packet is transmitted in long messages and bursts. This difference provides a cache allocation management mechanism to make the PoE switch downlink. The number of bursts supported by the uplink port is increased, and the probability of transmitting the problem is reduced. The security monitoring service fault location component is supported, and the packet loss and connectivity problems in the network are analyzed in real time.

Professional lightning protection

The professional built-in lightning protection technology supports the industry-leading 4KV port lightning protection capability, which can greatly reduce the damage rate of lightning strikes on devices in harsh working environments.

The link can support full line rate transmission

All ports of the optical network Video (ONV) commercial series switch can support full line rate forwarding, and customers can realize the convenient connection and expansion of the network without being affected by the transmission medium. The large backplane and the large cache switching chip solution are preferably used to improve the large file forwarding rate, and can effectively solve the problems of video jamming and picture loss in the high-definition monitoring environment.

Efficient, stable and green energy saving

A variety of green energy-saving designs, such as auto-power-down, If the interface status is always “down” for a period of time, the system automatically stops powering the interface and automatically enters the energy-saving mode. Supports one-button energy-saving mode, reducing energy consumption by controlling the indicator light on/off and port energy-saving status. The EEE energy-saving function is supported. If the port is idle for a period of time, the system will set the port to the power-saving mode. When a packet is sent or received, the port will wake up the port and resume the service.
