The LNK-POE56V Power over Ethernet (PoE) adapter is designed to supply operational power to surveillance cameras and wireless LAN devices such as access points, bridges, and routers. This adapter allows electrical current to flow through the Ethernet network cable, eliminating the need to connect a power supply directly to the wireless LAN device. Power and Data are combined on a single cable, eliminating the need for an additional power line and also reducing installation and labor costs.
