In order to effectively maintain the order and safety of the campus, we ensure the smooth implementation of teaching and scientific research work in schools and create better security for the students' lives and learning. Environment, we provide you with a full range of solutions - closed-circuit network monitoring system solutions.
Second, system design goals
When designing a network monitoring system, according to the school’s basic needs for the system, it is based on a rational structure, safety and reliability, mainstream products, low cost, and low maintenance, and provides advanced, safe and reliable information for your school. Efficient system solutions.
Reasonable architecture: It is to adopt advanced and reasonable technologies to structure the system so that the entire system runs safely and steadily, and has good conditions for expansion in the future.
Stability and security: This is the problem that every school cares about most. Only a stable operation system can ensure the smooth operation of the school network monitoring system. The advanced technology of the system is the guarantee and foundation of the high performance of the system, and at the same time it can effectively reduce the troubles of the personnel and system maintenance personnel. Good scalability is for the development of users. With the increase in the application time of security systems, the requirements for security systems will be even higher in the future. Extensibility guarantees that when the user has more requirements, the new equipment introduced can smoothly work with the equipped equipment to further expand and improve the performance of the system.
Mainstreaming of products: Whether the system adopts mainstream products today affects the overall quality of the system and whether it can obtain good technical support and complete technical documentation in the future.
In equipment selection, we will mainly rely on the specific needs of schools, taking into account the technological advancement of product manufacturers, whether the product is a mainstream product, the integrity of the original manufacturer’s product technical data, the original manufacturer’s technical support and product manufacturing. The school's development prospects. All of these are the conditions for ensuring that users receive good technical support, and they are also the basic conditions for ensuring the investment of users.
Low cost and low maintenance: Strive to have a good performance to price ratio, the products used should be simple, easy to operate, easy to maintain, and high reliability.
Whether the system has a good performance-cost ratio is an important basis for judging the merits of a system. The ease of operation and ease of maintenance of the system is a condition for ensuring that non-professionals use a good system. High reliability is the basic requirement for ensuring the operation of the system, and it is also the safeguard of easy maintenance.
For a typical network monitoring system, the following functions will be achieved when completed:
Set up monitoring points at the library depository and make video recordings. Used for immediate prevention or as an objective basis for post-analysis processing in the event of an emergency;
Set up monitoring points in the laboratory and make video recordings. The laboratory management teacher can monitor each laboratory in the computer room by monitoring the secondary control, which facilitates management;
Monitoring points, monitoring heads and alarms are set up in restaurants and stadiums. The flow of people in these places is relatively large. Managers can keep abreast of the situation at the scene through monitoring and deputy controls.
According to the college’s specific conditions, monitoring points, monitoring heads, alarms, and deputy control points are set up in special locations to improve the college’s technical protection facilities.
A monitoring point is set up in the apartment building of a student apartment. The apartment administrator can monitor the exit and entry of the personnel in the apartment building by monitoring the secondary control, especially during the night and during the student's class. It also greatly saves manpower; installing an alarm can provide timely alarm (such as fire) in the event of an accident;
Each camera is an information point, which is connected to the campus network through a network cable, and then monitors each camera through a monitoring PC. It can be monitored remotely through a browser, and PC monitoring can be set up at the teaching office, laboratory building, and library. point.
Third, system design principles and basis
The main basis of our design plan is to understand part of the user's needs and understand the standard of the IP network monitoring system, and propose a set of design ideas and network solutions. The monitored cable connection is a network cable. Using the network that the school has already built for the campus network can reduce the amount of construction work.
The protective cover is divided into indoor type and outdoor type. The indoor protective cover is mainly dustproof, and some also have a covert effect, so that the monitoring occasions and objects are not easily perceived and monitored. The functions of the outdoor protective cover include sun protection, rain protection, dust prevention and antifreeze. General outdoor enclosures are equipped with temperature relays. When the temperature is high, the fan is automatically turned on. When the temperature is low, it is automatically heated. When it rains, it can be manually controlled by the wiper. Some outdoor protective cover glass can also be heated. When there is frost on the hood, it can be heated to defrost.
Fourth, the system power supply and control room requirements
In order to ensure the normal and stable operation of the monitoring system, the system adopts an on-line UPS for centralized power supply; the monitoring server and the recording server use separate power supply circuits; the trunk adopts AC220V power supply, and the transformer uses the transformer to provide power supply at the nearby site; the central control room must be equipped with communication, safety, and Fire and other equipment; Central control room must be installed separately air-conditioning device, to ensure that the temperature of the control room is between 16 ~ 28 °C, relative humidity is not greater than 85%; control room, indoor lighting is sufficient, the illumination should not be less than 300 Lux; control room other Equipment and metal enclosures must also be equipotentially connected to ensure personal and equipment safety in the control room.

(C) The principle of campus monitoring system
The campus monitoring system is mainly composed of four parts: the camera part, the transmission part control part, and the display and recording part. The camera includes a color camera (with three variable lenses), an indoor all-around head, a dust cover, etc. The transmission section is mainly composed of a video server, and the control section includes image switching, motion control, and so on.
(1) Camera section
The camera part is the front part of the TV monitoring system and is the 'eye' of the entire system. The camera changes the monitored content to an image signal and transmits the digital audio and video signals to the monitoring and storage equipment of the control center through the video server. The camera part is the original signal source of the system. The quality of the camera part and the quality of the generated image affect the quality of the entire monitoring system. Therefore, the television monitoring system adopts a color camera integrated device with high definition and high sensitivity, an aperture, focusing, zooming and three variable lenses, and an electric indoor rotating 350 degrees in the horizontal direction and ±45 degrees in the vertical direction. PTZ; with a dust cover with anti-theft, anti-damage, dust-proof performance, and so on.
(2) Transmission section
The transmission part of the television monitoring system mainly consists of the transmission of image signals, the transmission of sound signals, and the transmission of control signals for controlling cameras, lenses, and pan-tilts. In this program, we take into account some of the specific circumstances of the school. We will use the Transcend Video Server of the Garment Digital Technology Co., Ltd. to transmit images, sounds, and control signals. Its main advantage is that the image will not be generated after transmission. Noise distortion can ensure the clarity and gray level of the original image signal. It mainly uses the school's existing local area network for transmission, which not only saves costs to the maximum but also eliminates the cumbersomeness of laying cables repeatedly.
(3) Control section
There are two options for the control section. One is to use the computer's mouse and keyboard for control, and the other is to use a dedicated control keyboard and matrix host to control.
In order to save system cost and extend the equipment's elimination cycle as much as possible, we recommend the use of the first program, using a computer to control.
(4) Display and record section
The main equipment in the display section is a computer monitor and a large-screen television (or projector). A large-screen television is used as a main display, and a computer display is used as an auxiliary display to facilitate management personnel in controlling the front-end monitoring point.
The recording part consists mainly of storage hosts and disk arrays. Each storage host can synchronously store 80 channels of audio and video, and can set the recording mode such as schedule recording by the storage host to save hard disk space.
