So far I'm not using them, but I don't have much experience to say how it works out. My cameras have the power and rj45 pigtails, and are outdoors. I attempted to seal the power connector by fastening an equal diameter wire nut the open end with shrink tubing. If the supplied RJ45 cover is weatherproof it should work out ok. The cameras are already too big without adding even more bulk to the setup. The cameras are mounted to trees.
