I have a Cat-6 cable running to an external PoE security camera that I'd like to have surge protected, but I'm unsure how to ground the protector. It has a prong coming off that I assume is the ground wire, but I don't know where to connect this. Is there an adapter to connect it to a close-by outlet and use that as ground? I feel that the location of the surge protector (indoors, about 8 feet high) is too far to try to attach it to an outdoor "to earth" pole.
Here is a link to the surge protector I'll be using.
