5 Best Poe Injectors

PoE technology stands for Power over the Internet. It means that instead of using two wires (the usual twisted pair for data transmission and a power cord), you can use a simple Internet wire that will be responsible for both data transmission and electricity supply to devices. This technology greatly simplifies the connection of IP cameras, IP phones, access points, and other network devices, and just greatly helps in a situation where there is no outlet nearby.

Connecting devices via PoE is safer since the twisted pair power supply is stable and does not depend on interference in the 220V network. And with the help of PoE, it is very easy to provide all devices on the network with guaranteed power. To do this, you just need to power the basic network hub from the UPS.

PoE provides centralized management and control of all network devices: switching on/off each individual device (including automatic), keeping records of the electricity consumed by each device. The interface of PoE hubs also allows you to determine the operating mode of individual devices and detect breakdowns on time.

The PoE connection looks aesthetically more perfect — fewer sockets, fewer wires.

PoE injector has the following advantages:

  1. Compact Form Factor. Due to its small size, the PoE injector can be placed almost anywhere – this lightweight, miniature device can fit in the human palm.
  2. Reduction of financial costs for the installation of equipment. The implementation of the power supply using PoE technology through a PoE injector is particularly relevant for radio bridges, IP and analog video cameras, which in most cases are installed on the street, and is a cost-effective solution, as opposed to laying separate electrical wiring. And most importantly, a switch with PoE is usually twice as expensive as a similar one, but without PoE.
  3. Protection of equipment from network surges and short circuits. When the wiring is unstable, it is very important to prevent the circuit boards from burning out in the event of a voltage drop. The PoE injector delivers consistently the same level of power to the powered device, thereby preventing malfunctions or even its breakdown.
