I wanted a really good camera since I don't have a rearview mirror, & my camera is my only view... all of the rear view cameras out there are just not real high end at all, I went with a sony superHAD 1/3" chip camera, 520 lines resolution, .02 lux native without infrared assist... it came in a large outdoor security camera case that I took apart & chopped down, then built my own bracket to mount it, isolated on rubber vibration dampeners & added an adjustment for finetuning the angle
this camera see's through the wiper hole in my tailgate... since I don't actually have to look through the window, there was no need for a wiper anyway... from outside you don't even see the camera, theres a tinted glass inside the hole, the camera is inside...
