Garmin BC 30 Wireless Backup Camera

I'm a fairly new RPod owner and find myself doing lots of reading and research.  I've been considering the Garmin Camera  mentioned above.  It pairs with many GPS devices and I'm thinking it would enhance visibility and improve safety. Not only does it show what's behind when backing up,  but it can also be set up to a constant display mode between rear view and navigation display simply by pressing a button.  Sounds interesting....

A few years ago, I installed a wireless backup camera on my r-pod.  I installed it inside, pointing out the bottom of the rear window.  It functioned well (as in it connected and displayed a clear picture), but the fisheye lens on the camera is designed to bring the ~20' behind a vehicle into focus which really limits its usefulness.

Originally posted by Outbound The camera really wasn't much use as a rear view mirror while travelling down the highway - the things I was interested in seeing were generally well beyond its 20' range.

Hmm, maybe I just complete passing a little sooner, but I'm thinking I might try out one of these: https://youtu.be/YJfhIQxSYq4?t=29s They're on sale at Canadian Tire until Wednesday for $99, wireless camera+monitor. I figure I'd be able to install as shown in this video for always-on operation: https://www.youtube.com/watch?v=X1ImZm9hDfU.

This is my first trailer, and I'm looking for any help I can get with "is it safe to merge/complete a pass" and "is there a child on a bike back there" type stuff. But on the other hand I'm not keen to waste $100 :)

Edit: Ack, that's just an add-on camera for $99. Thought the deal was too good to be true :(

We use our go pro. The app for the phone lets us use it as the screen.

I try to go by the old rule -- "There is no excuse for a backing accident if there are two people in the vehicle".    I try to hardly ever have to pass another vehicle in traffic.
