The AE-PI-G-90 1 Port Gigabit PoE Injector combines electrical power with Gigabit network speeds to provide Gigabit Power-over-Ethernet (PoE) over a single Ethernet cable. It is designed to supply data and up to 90 W of power to PoE-capable devices such as PTZ IP cameras or 802.11ac wireless access points. The PSE-803 allows you to mount your PoE device anywhere in a building, such as on ceilings or near entry ways, by eliminating the need for a nearby power outlet and attached power supply.
