The 5 Best Poe Injectors [Ranked]
A PoE (Power Over Ethernet) Injector is a device that adds power over an ethernet cable and is commonly used for security cameras that are positioned in areas where there’s no power supply available and VoIP phones.
Some plug directly into the wall outlet, while others mount to a wall with a cord that connects to the outlet.
The wall mounted varieties usually provide more flexibility when dealing with installation issues as you can always run an extension cord from the outlet to the box (Source).
How do they work?
A PoE injector plugs into an electrical outlet and inserts power into the ethernet cable running out of the system and to a particular device, usually one that’s hooked up to a network via ethernet, but not directly connected to a power supply (Source).
Buyers suggest when purchasing a PoE injector you make sure the device is able to supply power to all the ports simultaneously if you’re planning on adding to or scaling your system (Source).

Understanding Power over Ethernet
What is Power over Ethernet?
It is a technology with which electricity can be supplied through standard Ethernet cables. Supplying electricity in this way is useful as it gives you the opportunity of having only one cable which will provide a device both with electricity and the computer network. You can use it to power IP telephones, network cameras, wireless LAN access points, embedded computers, remote network switches, and other appliances. In most of these cases supplying power separately is often expensive, inconvenient or infeasible.
This technology is also comparable to POTS telephones. Both power and data are received with the same cable. For power over Ethernet, it is not necessary to change the already existing Ethernet cabling infrastructure.
A few general terms are used for describing this feature. The terms Power over LAN (PoL), inline power and Power over Ethernet (PoE) are synonymous terms that are used for describing the powering of devices through Ethernet ports.
Why use Power over Ethernet?
Supplying Power over Ethernet provides a number of advantages to an installation.
Among them are:
- Cost and time savings: it reduces the expenses and time of installing electrical power cabling. It is not required for network cables to be fit by a qualified electrician, and it can also be located anywhere.
- Flexibility: such devices as wireless access points and IP cameras can be located in any place where they are needed most without being connected to an electrical outlet. They can also be easily repositioned if necessary.
- Safety: POE delivery is smart, and is designed to avoid underpowering, incorrect installation, or overload of network equipment.
- Reliability: the source of POE power is central and universally compatible, and not a set of distributed wall adapters. POE power can be controlled to reset or disable devices and can be easily backed-up by some uninterruptible power supply.
- Scalability: as power is already available on the network, it is quite simple and effective to install and distribute network connection.
