Allows two PoE cameras on a single cable run for cost and installation savings Wisenet PoE extender cameras are designed to save integrators time and money when adding additional cameras to existing installations. For new installations, integrators can plan to run two PoE cameras per cable run, also saving on the number of ports and number switches required as well. For retrofit applications where an additional camera is needed, simply replace the old camera with a PoE extender camera, then install and connect a new PoE camera.
