FAQ

Q1: What devices can a gigabit poe injector power?

Standard PoE + power injectors can power a variety of PoE-enabled network devices, such as wireless access points (APs), IP network cameras, VoIP phones, wireless bridges, and IoT devices. These devices can obtain stable power and network connectivity via Ethernet cables, without the need for a separate power adapter.

Q2: What standards do PoE power injectors support?

Standard PoE power supplies typically support protocols such as IEEE 802.3af, 802.3at, or 802.3bt. 802.3af has a maximum power output of approximately 15.4W, 802.3at (PoE+) approximately 30W, and 802.3bt (PoE++) can provide higher power outputs of 60W to 90W to meet the power needs of high-power devices.

Q3: What is the power supply distance of a PoE power supply?

PoE injector adapter can typically be transmitted over Ethernet cables up to approximately 100 meters (328 feet). If a longer power supply distance is required, PoE repeaters or extenders can be used to extend the transmission distance while maintaining stable data and power transmission.

One Less Wall Wart – Love It

I've got a PoE security camera mounted in a spot where running an outlet would've been a huge pain. This little injector lets me just run one Ethernet cable and be done. The gigabit speed is great – no drop in quality, and my camera has been rock solid. Just plug and play, no software nonsense. Honestly if you're tired of messing with power adapters and extension cords for your network gear, grab one of these. Makes life a lot simpler.
