Discouraged with wireless back up camera
My solution was use facetime between two iPhones or between your Mac and iPhone. Put your iPhone in the iPhone holder and place it at the back of your trailer. No more expensive wireless back...

Mine works great, but It stays on while in motion or until I'm setup, that way I can watch the toad going down the road, and it has sound so I can hear DW back there yelling at me when backing in. ;)
