I have one but can't think of it right off the bat. It's a yellow one
The thing I hate about it is it doesn't hold a charge for 3-4 months so I have to remember to charge it before I need it if I haven't camped in a while. And I wish it had a little larger field of view. I can't see the trailer receiver until I'm really close to the trailer. So I use landmarks on the trailer to line up until I can see the trailer tongue come into view. But I like the camera so much better than those ball things - although those work in a pinch.
Swift Hitch - that's the brand. I got it at PPL.
