I have one of
these on my trailer, and though it distorts the picture because of the wide angle lens, I find it comforting to be able to see behind me when I am merging into traffic or passing.
This unit is well made and has performed well, rain or shine, for over a year.I have one on the memsahib's SUV and had one on my previous PU. They give a good clear image and have infrared LEDs for night vision, which works well. Once I got used to the grid, which is intended for backing up, I can get a rough idea of how far behind me the next car is. This was the first thing I ordered for the new trailer. I tried a wireless camera on my TC and had marginal luck with it, so I hard wired it as I have all the others. JM2C.
