LOL .... I promise you, no one will ever steal your camera. They may snag the $16+- easily, removable, plastic cover but they are not going to get or even want the camera. Sure, there may be the rare exception to what I spew but it will be a rare day in hell that someone steals that camera.
Forgot to mention.... what you do need to worry about in regard to that camera is that you or some nitwit tire jockey, does not, when removing the spare, let it drop down on the camera and break / crack it's housing. NOW, that is something to worry about.
Funny story. Like so many people do, I used my rear view camera for a family Disney World trip earlier this year. It was hard carrying that wheel around all day. Had no idea it separates. And don't get me started on family photos with Mickey. Try finding a passerby who can lift that tire.
I was thinking the same question being my neighborhood is like mini Beirut. Just last week they stole a persons truck lid which I have never seen before literally took the trunk lid off an accord ! 1 week later another Honda was left on milk crates as they took all the wheels. I am on the border of the Bronx in NY and have seen it all. lol I have a 2019 JLUR on the way and will be watching it at night.
