From the literal meaning, the PoE switch has the PoE function, that is, the power supply through the network cable. PoE switches like Feng Runda can not only exchange data, but also support the function of power supply to the network cable, and they are all standard.
The ordinary switch is mainly a function of data exchange, and does not have the function of power supply.
Nowadays, HD cameras are basically powered by PoE switches, which do not require power wiring like ordinary switches, and are more reliable.
That is to say, there is no connection power line in a network high-definition camera, directly connected to a common switch through the network, and this time, the camera is not working.
On the contrary, it can work normally through the PoE switch directly.
Security monitoring and control system use PoE switches have many advantages, in addition to extra cables, it can save cost, the system is more flexible, the later upgrade and maintenance is simple.
PoE switches are also standard and non - standard, and choose standard PoE switches at the time of selection, so that the security of the camera can be guaranteed to the maximum extent.
Non standard equipment is easy to burn. If you burn the camera, it will be more than enough.
