Anyone ever used this back up camera?

My wife bought me a Furrion wireless observation cam for Christmas (Walmart) and I mounted it up high on the back of the camper. Comes with a LCD screen that goes on the dash (or on the windshield with a suction cup mount. Works well and has the infra red night vison as well. It;s switchable between observation and backup (with the grid).

Really helps me to see who is tailgating me...

Big plus is it's wireless, so no cables.
