How to choose the right Poe power supply switch?

Release date:2017-12-08 Author:华明威视 Click:

 The following points should be noted when choosing the right POE power supply switch?

1. determine that the PoE power protocol supported by the power supply protocol supported by the AP or IPC (such as 802.3af, 802.3at, or non standard PoE) needs to be consistent with the power terminal. The single port output power of the 802.3af standard PoE switch is 15.4W, and the single port input power of the 802.3at standard PoE switch is 30W. The 802.3at standard PoE switch is recommended for the large power receiving equipment.

2.In addition to the power supply protocol and the single port output power, the PoE power supply switch needs to take into account the overall power of the PoE switch, the greater the total power, the stronger the power supply capacity (the maximum power supply must be greater than the total power of the receiving end).


3.PoE switches are divided into network management PoE switches and basic PoE switches. The basic PoE switch is mainly to provide the PoE power supply


In addition to providing PoE power supply, network management PoE switches can also flexibly configure port power supply time and priority, and can specify a more reasonable power supply plan.



4.The port of PoE switch also has a number of points, ranging from 4 to 24 ports. Please consider the number of receiving terminals.


The number of PoE power supply ports.



5.The transmission rate of PoE switches is between 100 trillion and Gigabit, and port needs are considered according to the receiving terminal and business requirements.


The highest rate to support. In general, the Gigabit PoE switch performs better than the 100 megabit PoE switch, with network supervisor.


For example, if the surveillance device is equipped with high-definition cameras, but the bandwidth is not enough to support HD communication, it will appear.


Packet loss phenomenon affects monitoring effect (delay, Caton). To achieve HD and smooth effects, you can use Gigabit Po.
