PoE (Power over Ethernet) was created to supply power via the same ethernet cables already connecting a system for the purpose of data transmission.

PoE power is especially useful for Security Systems since IP Cameras will already be connected to an ethernet system in order to deliver the recorded data over the network. In a PoE powered system the same ethernet cable used for data, is also used to deliver power to the camera, light or other connected device. PoE power also allows easier Plug & Play type of connections compared to conventional and low-voltage powered devices.
