Power over Ethernet (PoE, EEE 802.3af-2003) is a cleber standard to supply ethernet connected devices, with power up to 15,4 Watt per PoE network switch port. The supply voltage are transmitted within the same ethernet cables as the data stream, and thereby only one CAT cable is needed, for e.g. IP cameras, Wi-Fi access points, door stations etc. The PoE standarden has been further developed into the PoE Plus/+ version (IEEE 802.3at-2009), which can delivery up to 25,5 Watt pr. connection, and are often utilized for HD network IP cameras.

We recommends minimum Category 6 or 6A ethernet cables for a stable connection of PoE network equipment.
