Power-over-ethernet IP cameras draw power down the network cable, so they don't need a second cable to connect to mains. Usually, this requires a PoE compatible switch or recorder, but this PoE Injector is a fantastic solution if this is not possible. It connects to mains and sends power up to 100m down Cat6 or Cat5e cable to provide power to a camera.

The injector uses 48V "active" PoE, so you don't need a splitter at the camera end. Please note injector is not compatible with PoE+, or higher voltage protocols.
