Choosing the right switch for smart campus security transmission network power supply is no longer difficult

With the introduction of the concept of smart cities, the concept of "smart parks" has entered the public eye. The Smart Park is 2.0 based on the park's informatization and is an important manifestation of a smart city.

The smart park is based on green, energy saving, and security, covering smart access control, smart visitors, smart parking, security monitoring, fire linkage, time and attendance, smart office, broadcasting, equipment inspection and other systems. The management platform realizes centralized management and intelligent management and control of each network device.

Four Challenges Facing Smart Park Security Transmission

In the era of the intelligent Internet of Things, the data collected by each terminal device must be transmitted to the management center, and the connection and interconnection between the terminal device and the cloud can be realized. The network transmission device is an integral part of the intelligent park information system.

As the security industry moves towards the era of the Internet of Things, massive front-end products bring massive data, and the test of network transmission systems is getting bigger and bigger, and the requirements for stable and smooth communication of network equipment are also higher. Taking smart park security transmission as an example, the security transmission system faces the following challenges:

First, the distribution of front-end equipment is relatively scattered, and it is necessary to achieve dead-end coverage, which increases the requirements for power supply and transmission of security equipment;

Second, there are many types and quantities of equipment, complicated installation and power supply requirements, and difficult installation and configuration of equipment and subsequent operation and maintenance;

Third, many surveillance cameras are installed outdoors, and are easily affected by complex environments such as lightning strikes, which causes the stability of the entire security system to be tested.

Fourth, the large-scale network leads to increased security threats to the campus network system, such as broadcast storms and virus attacks, which often cause equipment downtime and system instability.

Integrated Security System in Smart Park

How to solve the problem of security transmission in smart parks?

Combining the high-definition, intelligent, and visual development trends of security applications, Utop Smart Park Security Solution is based on the corporate park security network, and integrates PoE intelligent power supply technology, self-healing network technology, cloud platform technology, etc. in the intelligent system , Effectively solve the problem of campus network deployment and management and maintenance.

1.Photoelectric hybrid to solve short-distance and long-distance transmission problems

Ethernet switch ports are divided into optical and electrical ports. Electrical ports are connected to network cables and optical ports are connected to optical fibers. The transmission distance of the network cable is generally 100 meters, and the optical port can reach 1KM to 100KM depending on the type of fiber. When the transmission distance is less than 100 meters, the network cable is generally used for transmission, and when the transmission distance is long, optical fiber is used.

From the perspective of park security applications, to achieve indoor and outdoor dead space-free coverage, the switch uses a photoelectric hybrid port design, which can effectively solve the problem of short-distance / long-distance transmission in the park. With the expansion of the campus network, the increase of equipment, and the growth of data, the upgrade of network bandwidth from 100M to Gigabit becomes inevitable. The full Gigabit photoelectric hybrid network fully meets the data transmission requirements of the smart park.

The 8/16 / 24-port full Gigabit managed PoE power supply switch launched by Utop provides 8/16/24 downlink Gigabit PoE electrical ports and 2/4/4 uplink Gigabit optical ports. The product uses a large cache The chip design can meet the gigabit network optoelectronic hybrid networking and 4K high-definition video surveillance transmission requirements, reducing network stalls and mosaics.

It is worth noting that this series of switches can extend the transmission distance of the network cable to 250 meters through automatic speed reduction negotiation, which meets the long-distance data transmission and power supply requirements of the smart park.

2. PoE intelligent power supply for continuous and stable operation of security equipment

The security coverage of the park is wide, involving entrances, perimeters, warehouses, parking lots, production lines, office buildings, dormitories and all corners. The scene is complex, the equipment is numerous, and the interference is large. The continuous and stable operation of the equipment is very important.

The PoE intelligent power supply method can not only solve the data transmission networking problem, but also provide power to the front-end equipment through a network cable, effectively reducing wiring costs and workload. The 8/16 / 24-port full Gigabit managed PoE power supply switch launched by Utop supports the IEEE 802.3 af / at (PoE +) power supply standard, and the PoE power supply of the whole machine reaches 135W or 230W.

In addition, this series of products support the PoE timing management function through the WEB interface, which can be set to stop the power supply to some devices during non-office hours to save energy; it can also be set to restart the device at a specified time through PoE scheduled task management to avoid buffer overflow The collapse of equipment such as IP cameras or APs ensures stable and reliable power supply.

3.QVLAN + DHCP to solve broadcast storm and device group management

With the expansion of the scale of the park, the security threats to the network system also increase accordingly. For example, broadcast storms, ARP, and DOS virus attacks occur from time to time. The slightest impacts the normal operation of the business and severely causes the network to be paralyzed. Therefore, network planning and equipment selection in advance can greatly reduce network failures. For switches, their network management functions and security policies are also important.

Utop 8/16/24 port full Gigabit managed PoE power supply switch has rich Layer 2 network management functions and security policies, such as support for 802.1 QVLAN, DHCP, 802.1x authentication, ERPS, one-click ring network and other functions, making The switch and the connected devices are protected from virus attacks, effectively solving the problems of broadcast storms and device group management, and ensuring the safe and stable operation of the devices.

4. Support cloud management and solve the problem of equipment later maintenance

As mentioned earlier, there are a large number of security equipment in the smart park, and the faulty nodes are scattered. Not only is it difficult to install and deploy the equipment, but the later operation and maintenance management is also not simple. How to ensure that the equipment continues to be stable and online, and 7 * 24h continuous safe and stable operation? How to detect equipment anomalies in advance and solve problems quickly? How can I prevent the webcam from stuttering and frequently occurring offline?

As the security industry moves towards intelligent applications, intelligent management and automatic operation and maintenance of equipment have become a general trend. Remote management and automatic maintenance of equipment through cloud platforms have become user requirements.

Utop's managed switches support cloud platform management. Through the cloud platform, unified monitoring and unified visual configuration of the switch status can be realized. It can realize the online status and port traffic of the switch. It supports visual operation and maintenance management based on automatic topology and GIS maps. ; Can realize the configuration and management of IPC equipment.

The remote intelligent and visual management and maintenance of the equipment through the cloud platform greatly reduces the equipment operation and maintenance management of the smart park security system and makes equipment maintenance easier!
