This is the push on F-connector I use at the camper for quick disconnection of the rear camera.
This is the camera I use on both the truck and the camper. Notice it does NOT have LED for night-vision. on these cheap cameras, they only serve to light up the lens and that makes them pretty useless at night. I prefer to light up the area behind and am planning to add some bumper LED lights for backing up.
One note about these cameras: the better imaging cameras are CCD but are expensive; the worst is a CMOS. There is a newer type called CMD that are kind of in the middle. Pretty good imaging and a decent price. I prefer the CMD.
This is a terrible picture but if you look closely you'll see the camper cam in the window. It is affixed with 3M command strips. holding up well so far.
