The main application fields of Poe switch are wireless AP, IP phone, IP webcam and other network applications based on IP terminal products, and its power demand generally does not exceed 30W. By using Poe technology in the network, the problem of power supply trouble of wireless AP and network camera in ceiling, corridor and door head is solved. At the same time, Poe switches can also provide QoS, VLAN, ACL and other management functions to meet the network requirements for equipment performance and functions.
Security demand analysis
In the field of security, Ping An City is the largest and most complex huge system, involving many sub areas such as public security monitoring, command and communication, investigation and case solving, standardized law enforcement and social services. The scale of video access ranges from thousands to tens of thousands, and there are countless webcams. How to construct and obtain electricity more conveniently determines the reliability and stability of the whole network monitoring system to some extent.
Poe switch has unique advantages in the field of security. It supplies power to the network monitoring camera through the network cable, eliminating additional power wiring, greatly reducing the construction cost and improving the role of monitoring.
Monitoring scheme topology
Scheme overview and description
The whole monitoring system adopts Poe power supply, and the networking mode is flexible. The network surveillance camera is connected to the POE switch, then the data is uploaded to the aggregation / core switch, and finally the video data is transmitted to the terminal display device through the optical fiber.
Non Poe webcams can also use Poe power normally after using PD separator.

Program features
With POE power supply, the power signal can be added while transmitting the network signal. As long as the power supply is connected at the office end, it can supply power to the user end and other network terminals through different transmission cables, eliminating the trouble of additional wiring and power collection of the network camera. The transmission distance of Poe power supply is up to 100m. Even if the webcam is far from the power supply equipment, it can obtain a stable power supply. Through a variety of Poe switches of different specifications, the networking is more flexible and changeable to meet the needs of various monitoring environments.
