Power over Ethernet (PoE) is a feature supported by devices that enable them to be powered by ethernet cabling. This technology cuts down on connections by combining data and power into a single cable.
PoE is a great way to cut down on installation costs and improve reliability by removing a point of failure, the second cable for power. With devices that support this technology, it's possible to provide both data and power connectivity by plugging in a single network cable, making everything easier to maintain.
