30W Gigabit PoE Injector

The DiySecurityCameraWorld 30W Gigabit PoE Injector adds Power over Ethernet to a single network drop. It delivers up to 30 watts over a Gigabit link while passing data at 10/100/1000 Mbps. The unit complies with IEEE 802.3at and remains backwards-compatible with 802.3af devices. A built-in AC supply accepts 100 to 240 VAC at 0.8 A.

Installers needing one powered camera

This injector suits installers who need to power a single PoE+ device such as a camera or wireless access point where no PoE switch exists. It automatically detects the connected device and supplies either 30 W or 15.4 W to protect low-power equipment. Buyers who must power multiple devices from one source or who require a multi-port midspan should look at a different solution.

Fits a single-cable run with standard AC power

The injector sits between a standard AC outlet and the Ethernet cable run, requiring only a mains socket and a Cat5e or better cable. It uses Mode B pin assignment on the PoE port (pairs 4/5 positive, 7/8 negative) and provides a green AC power indicator. The package includes the injector and a power cord, freeing the installer from sourcing a separate 48–56 VDC supply.

Questions about this item

Do I need a separate power cord for the injector to work?

A standard AC power cord is included in the box, so no extra mains lead is required.

Will this injector power a legacy 802.3af camera while keeping gigabit speeds?

Yes, it auto-negotiates 15.4 W for af devices and passes 10/100/1000 Mbps data on all four pairs.

How can I confirm the injector is delivering power correctly after I connect it?

The green AC Power LED lights when mains voltage is present, and the attached PoE device will power on if detection succeeds.
