Aside from what’s included in the Sight package, users will need to provide a POE+ source (either via a network port or POE+ injector) and CAT6 or above cabling.  The Sight Dongle, included in the package, is needed for installation. If there is no LED activity, check the POE power source and make sure that your network switch / power injector supports at least 802.11at parameters or above. POE on 802.3af parameters is not compatible
