The security monitoring system is an important means of crime prevention and an important means of finding and tracing accidents. The school is a very densely populated place, and various conflicts or emergencies are prone to occur. However, the inspection and processing according to the school manpower will increase the management cost. , And the effect is not obvious, and it does not play an obvious role in safety precautions. It is very important for schools to deploy a security monitoring system, which plays a role of pre-prevention, timely handling during the event, and retrospect after the event.

In order to ensure a high degree of safety in the campus, the ability to obtain evidence and confirm emergencies, and the school security personnel’s macro-monitoring of public places in the campus, cameras and alarm probes have been installed on major arterial roads, important places, and important areas in the campus to assist The security management department obtains intuitive images of the on-site situation in the campus and grasps the overall situation of the campus in real time. Once an alarm occurs, the video system will be linked to collect evidence in time to provide a basis for subsequent analysis and evidence collection.

System functions

Surveillance front-end: It is mainly responsible for the collection of various audio and video signals. Through the deployment of network cameras, dome cameras and other equipment, the collected information is transmitted to each monitoring center in real time.

Transmission network: The entire transmission network adopts the three-layer transmission architecture design of the access layer TBC-MC3612ES20A, the convergence layer TBC-S5108GE16GF, and the core layer TBC-S5348GE-4GE4TF. The front-end network equipment is connected to the access switch nearby, and the access switch is connected to the aggregation layer switch through optical fiber, and the aggregation layer is transmitted to the core layer through optical fiber.

Master Control Center: Responsible for the access, display, storage, setting, etc. of HD monitoring points in scattered areas of the sub-control center; mainly deploy core switches, video integrated platforms, large screens, cloud storage, clients, platforms, video quality diagnosis servers, etc. .

Sub-control center: Responsible for the functions of access, storage, browsing, and setting of high-definition monitoring points in the front-end scattered areas; mainly deploy access switches, clients, etc.

Project product

①Access layer transceiver

TBC-MC3612ES20A series 10/100/1000M adaptive fiber media converter through 100Base-TX or 1000Base-TX to 100Base-FX photoelectric conversion between the traditional 100M Ethernet or 1000M Fast Ethernet through the Fast Ethernet fiber optic link extended to 120 km range, to meet the long-distance, high-speed , High-bandwidth fast Ethernet working group user needs, the product performance is stable and reliable, designed to meet the Ethernet standards, and anti-lightning protection measures, especially for telecommunications, mobile, China Unicom, safe city, radio and television, railway, military, financial securities, customs, civil aviation, maritime transport, electricity, water conservancy and oil fields and other broadband data network and require high reliability data transmission or the formation of IP data transmission network area, it is the best application equipment for broadband campus network，intelligent broadband district fiber to the floor , Fiber to the home and video surveillance .

②Convergence layer switch

TBC-S5108GE16GF 16 optical 8 electrical (millions of high-definition network optical transceivers) Ethernet optical fiber switch 16 1000M standard SFP sockets and 8 10/100/1000M adaptive RJ45 ports, if fixed RJ45 electrical ports are not used, the switch is full SFP Of 16 full Gigabit optical switches. Users can choose different SFP modules according to their needs, such as multi/single mode, single/dual fiber, single mode 550m～120Km, etc. It can realize the seamless connection between the optical and electrical signals of 1000M Ethernet. It can better meet the different needs of different users than a gigabit switch with a fixed optical module. The switch chip adopts the latest American IC, with stable performance, high quality, simple and convenient to use, and has a high cost performance. It is suitable for small optical fiber Ethernet and optical fiber Ethernet network with special needs.

③Core switch

TBC-S5348GE-4GE4TF This series of switches is a 10-Gigabit Layer 3 switch launched by the company. There are currently four models. This series is an enhanced IPv6 10-Gigabit Ethernet switch with advanced hardware processing capabilities and the most abundant services. characteristic. The whole machine adopts a modular design and supports up to 4 10 Gigabit SFP+ ports. When realizing Gigabit aggregation or access, it retains the expansion capability of further supporting 10GE, supports IPv4/IPv6 hardware dual-stack and wire-speed forwarding, so that customers can deal with it calmly The upcoming IPv6 era provides high-capacity switching capabilities, which can be widely used in the convergence layer of large-scale governments, enterprises and institutions; or the core layer of small and medium-sized networks.
