I use cuddyback cameras with the steel bear cages on them on my WI land. I chain and padlock that cage to the tree, but a couple years ago I had someone cut the chain and steal the camera. I'm guessing that someone was trespassing and realized they got their picture taken on my trail camera, so they drove back with a bolt cutter after dark (they drove through a tree planting and standing bean field). After that, I'm not really sure whether locking the camera to a tree really does any good.
