PoE switches are equipped with power supply equipment, which brings convenience to the field of use and makes PoE switches widely used. However, many users will report that their PoE switches are unstable. So, what are the unstable factors? Next, let’s follow JHA TECH to understand it!

The first thing to consider is the issue of transmission distance. Although the PoE power supply switch is convenient and flexible, the straight-line distance of power supply cannot exceed 100 meters.There are both power signals and data signals in the network cable. There is no distance limit for the power signal, which can be 200 meters or 500 meters.But data transmission can’t do it, because it has loss, the longer the distance, the greater the loss. In order to ensure the best video picture effect, according to the data transmission standard, the distance of PoE power supply cannot exceed 100 meters.

Secondly, the choice of PoE switch is inappropriate: that is, the quality of the selected PoE switch is not good enough, or the model is wrong. The choice of cheap POE exchange has a great influence. In a medium and large monitoring project, or a place with very high monitoring requirements, choosing some low-priced PoE switches is likely to cause problems, because product quality and performance cannot be 100% guaranteed.

How to change the instability of a PoE switch? It is actually very simple: a good quality network cable, a high-performance PoE switch, a suitable power supply distance, and a suitable power supply model.
Everything is not 100% advantageous, and PoE switches are no exception. No matter how popular it is in network monitoring, it also has its shortcomings, but you must not be greedy for cheap when choosing.
