What is PoE?

Power over Ethernet. Power over Ethernet (or PoE) is a technology that allows LAN-enabled devices, such as network cameras to be powered using standard Ethernet cabling. Each individual IP Camera transmits its images and receives power through a single Ethernet cable. This eliminates the need for complicated and expensive cabling and can often operate along with an existing wired network. PoE also offers greater flexibility for installation since cameras can be placed in areas where power outlets are not readily available. Another benefit of PoE technology is it enables easy installation of UPS (uninterrupted power supplies) for video surveillance applications requiring 24-hour surveillance that will continue operating even during power outages.
