Gigabit PoE injectors support different power requirements by supplying power through Ethernet while maintaining gigabit data connectivity, with options for PoE, PoE+, and PoE++ devices. Depending on the injector, output may range from about 15 watts for PoE to 30 watts for PoE+, and up to 60 or 90 watts for higher-power PoE++ equipment such as PTZ cameras, access points, and other network devices.

Yes, a gigabit PoE injector can add power to the Ethernet connection between a non-PoE network switch and a compatible PoE device while passing gigabit data. Connect the switch to the injector’s data input, then connect the injector’s PoE output to the device, and confirm that the injector’s PoE standard and power output match the device’s requirements.

Plan for a gigabit Ethernet connection with RJ45 cabling between the network switch, injector, and powered device, using structured cable and staying within the cable-length limits for the installation. Provide the injector’s required AC power source, and match its PoE standard and output, such as 30W, 60W, or up to 90W, to the connected device’s needs.

Choose a gigabit PoE injector with higher power output when the connected device, such as a PTZ camera, access point, or other high-power PoE equipment, requires more wattage than the network switch provides. Choose multi-gigabit data support when the connected device and network infrastructure support speeds above 1 Gbps, such as 2.5 Gbps or higher, to help accommodate greater data throughput.
