PoE Injectors, Splitters & Extenders

Power over Ethernet (PoE) lets a single network cable carry both data and power to devices such as IP cameras, wireless access points and door controllers. This collection brings together the products that add, split or extend PoE on a network: PoE injectors (also called midspans), PoE splitters and PoE extenders.

A PoE injector adds power to a data connection when your switch or recorder has no PoE ports, or not enough power budget. A PoE splitter does the opposite, separating power and data at the far end so a non-PoE device can be run from one cable. A PoE extender repeats the signal and power to push a link beyond the standard 100 metre Ethernet limit, and some kits do this over coax or long-range links.

When choosing, check the following:

• Standard and wattage: 802.3af (up to 15.4W), 802.3at PoE+ (up to 30W) or 802.3bt PoE++ (60W to 90W). Pick a unit that meets or exceeds the device's requirement, which matters for PTZ cameras, heaters and Wi-Fi 6 access points.
• Port speed: Fast Ethernet, Gigabit, 2.5G or 10G, matched to your network.
• Environment: indoor desktop units, DIN-rail industrial injectors and IP67 outdoor models are all available.
• Ports and power input: single or multi-port, and mains or DC supply.

The range includes products from TRENDnet, Axis Communications, Veracity and Bosch, among others. If you need to power many devices from one location, a PoE switch may suit better than individual injectors, and our network switches and CCTV accessories collections cover the rest of the installation.
