Door Access Control, IP Camera Systems, IP PA Systems use PoE
Power over Ethernet (PoE) is the easiest way to provide power to many network-attached devices such as IP cameras, door access control systems, and IP paging and Intercom systems.
The network cable transfers both data and power to the device, making installation very simple. The network cable includes up to eight wires. The data uses one set of wires, while the power uses another set of wires in the network cable.
This article describes how access control systems, IP Camera Systems, and IP paging systems utilize power over Ethernet (PoE)
