The Power over Ethernet (PoE) allows both power and data to travel through a single Ethernet cable. Where the cable goes, the power/data arrives. There is no need to deploy the power sources at each of the IP devices. It is a handy tool to install the IP camera system, the access point for WiFi coverage, VoIP phone, etc. The PoE injector is power supply equipment that can inject the DC power to an Ethernet cable. It converts non-PoE devices such as a router and switches into PoE compatible. You might also need a PoE splitter if your edge devices don’t support PoE either. The PoE splitter separates the power from the Ethernet cable and converts it to DC12V in most cases.
