PoE Injector

A PoE Injector (Power over Ethernet Injector) sends both power and network data through one Ethernet cable, allowing devices like IP phones, cameras, and access points to work without a separate power adapter. PoE is typically provided by a PoE-enabled network switch—if your phone's switch is not labeled “PoE,” or their devices require a separate power brick (power source), then you likely don’t have it. A PoE injector is an easy way to add power when PoE isn’t built into the network.
