PoE Injector Splitter Buying Guide
PoE injectors add power to Ethernet cables; splitters separate power from data at the device end. Essential for devices in locations without nearby power outlets.
PoE Standards
802.3af (PoE): 15.4W for cameras, phones. 802.3at (PoE+): 30W for PTZ cameras, APs. 802.3bt (PoE++): 60-90W for lighting, digital signage.
Selection Tips
Match injector power to device requirements. Check voltage compatibility (48V standard). Gigabit vs Fast Ethernet speed. Surge protection for outdoor use. Splitter voltage must match device DC input.
