Power Over Ethernet – Save Money and Increase Efficiency

Power over Ethernet, or PoE, is a technology that allows network cables to carry both data and electrical power. This eliminates the need for additional power outlets and reduces installation costs. In addition, PoE can increase network efficiency and reliability. Let’s take a closer look at how PoE works and how it can benefit your business.

How Power Over Ethernet Works

Power over Ethernet (PoE) is a technology that allows network cables to carry electrical power as well as data. PoE was originally designed for use with Voice over IP (VoIP) phones, which require a small amount of power to operate. However, PoE can also be used to power other devices such as security cameras, wireless access points, and LED lights.

PoE works by supplying power through the unused pairs of wires in a standard Ethernet cable. A special injector or switch is used to insert power onto the cable. The receiving device (such as a VoIP phone) contains a chip that regulates the amount of power it draws from the cable. This ensures that the receiving device does not draw too much power and overload the system.

The Benefits of PoE

There are several benefits of using PoE for your business:

– Cost savings: No need to install additional outlets or run new wiring. If you’re already using Ethernet cables for your data network, you can add PoE devices without incurring any additional costs.

– Increased efficiency: PoE devices can be installed anywhere there is an Ethernet connection, without regard for proximity to a power outlet. This gives you more flexibility when it comes to placing devices such as wireless access points or security cameras.

– Simplified installation: Installing PoE devices is typically much easier than running new electrical wiring. In many cases, it’s simply a matter of plugging in the device and connecting it to your network.

– Enhanced reliability: Since PoE devices receive their power from the network itself, they are not affected by disruptions in the building’s electric supply. This can be important for mission-critical applications such as security systems or VoIP phones.

– Greater sustainability: By usingPoE, you can reduce your energy consumption and your carbon footprint. This is becausePoE devices are typically more energy-efficient than those powered by AC adapters or batteries.


If you’re looking for a way to save money and increase efficiency, Power over Ethernet may be the perfect solution for your business. With PoE, you can eliminate the need for additional outlets and simplify installation process. In addition, PoE can provide enhanced reliability and sustainability benefits.
