I have a 3 camera security system. When I installed it, I made a hole on the outside wall and ran all 3 wires through there. Once I finished I used caulking to seal the hole and make it water proof. It is now 5 years later and one of the cameras does not work and I diagnosed the problem as being the wire for that camera. I will have to remove the caulking (which will be a pain) and run a new a camera wire in there. My question is, do they sell something like a box that I can put outside that will be waterproof so that I can run the wires through there more easily and when I have to replace a wire I just open up the box and have easy access to the hole in the wall. Thank you in advance.
