4-Port Passive PoE Injector Module – DC 9–48V for IP Cameras & Access Points

Overview

This 4-port passive Power over Ethernet (PoE) injector lets you supply power and data over a single Ethernet cable, powering up to four devices remotely up to 100 metres (328 ft). It adds PoE capability to any existing switch or router without replacing your network gear.

Simple to install and manage

Connect a suitable DC supply (9–48V) to the 2.1 × 5.5mm jack, then plug in your CAT-5/6/7 cables — power is injected on pairs 4/5 and 7/8 while data uses pairs 1/2 and 3/6. Centralise power for IP cameras, VoIP phones and Wi‑Fi access points and reboot all four devices from one location.
