Model AV100P2 is designed to extend connection distances from a PoE source to an output device another 100 m (328 ft.) via Cat5e or Cat6 cable. You can cover even longer distances by cascading these extenders on a network. It does not need any additional power supply, as it draws the power from the PoE input. Simply connect the PoE In port with your PoE injector or PoE switch, and connect the PoE Out with the PoE device that you wish to connect.
