Power over Ethernet (PoE) is a technology that integrates power into a standard LAN infrastructure. It
enables power to be provided to the network device, such as an IP phone or a network camera, using
the same cable as that used for network connection. It eliminates the need for power outlets at the
camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure 24
hours a day, 7 days a week operation.
