Back up camera location

I have a Voyager Wireless system and it works good. Yes it does drop the signal once in a while for a second or two but it does come back quickly. I mounted it below the middle clearance light, and I can see right and left and back without a problem. The system I bought also has night vision and sound so the wife can let me know if there is a issue when backing. The system did cost me $400+, but I have used it one 3 different trailers. I do have the antenna on the front for best reception. Resolution is good and camera is detailed not fuzzy. Bought it from RV Cams.
