With a Ubiquiti UniFi PoE switch, you can power your UniFi access points via the network cable. That way, you don't need a separate AC adapter or PoE injector for this. You can also connect other devices like security cameras and network phones to Ubiquiti PoE switches. You can manage all Ubiquiti UniFi switches with PoE in the same UniFi Network environment. Your Ubiquiti UniFi access points also work via this cloud management environment. That way, you can quickly and easily make changes.
