Choose a Power over Ethernet (PoE) injector with an output wattage that meets or exceeds the powered device’s rated or peak demand, and match the required IEEE 802.3af, 802.3at, or 802.3bt standard. Lower-power cameras, access points, and control processors may use 15W or 30W injectors, while PTZ cameras and other high-power devices may require 60W or 90W, so also confirm the injector’s data speed and the device’s compatibility.

When selecting a PoE injector, match the device’s power requirement to an IEEE 802.3af, 802.3at, or 802.3bt injector, which can provide standard, PoE+, or higher-power PoE output. Choose a network speed that matches the installation, such as 10/100/1000 Mbps for standard Gigabit connections or 2.5, 5, or 10 Gbps for multi-gigabit networks.

Review the injector and powered device requirements for the appropriate Category cable, link distance, data rate, and PoE standard, with some models supporting up to 100 meters or 330 feet. Confirm the available AC input and plug type, provide a nearby outlet, and plan for the injector’s mounting needs, such as wall, rack, or above-ceiling placement when supported by the enclosure.

Yes, many PoE injectors can add power for high-power devices, such as PTZ cameras and access points, while connecting them to a non-PoE network switch. For multi-gigabit devices, choose an injector that supports the required PoE standard, power output, and Ethernet speed, then connect it between the switch and powered device.
