I'm ready to pull the trigger on a 5231 and 2231 but I cant figure out junction boxes. The only place I can mount cameras to is on my vertical wall outside, where it will be uncovered and rained on. I understand that the normal junction box for this is the PFB203W but I really prefer the PFA130 because it is much stealthier and doesn't stick out as much. Does that junction box work in uncovered areas where it will be rained on? I can't wait to get these things but I want to make sure the cameras are protected first.
