A PoE switch carries data and power over the same network cable, so IP cameras and access points need no separate power adapter. Here you will find Hikvision smart PoE switches from 4 to 24 ports, Tenda desktop PoE switches and the TP-Link 28-port Easy Smart PoE+ switch.

Tip: count your cameras and leave spare ports, and choose Gigabit if you run high-resolution cameras or plan to grow the network.
