I have a deer cam and it has a cable that goes through the bottom. I am not sure about the stealth cam box. I had one stolen last year (deer cam) and built a bear box that I will lag and chain to the tree. If they want it they will get it, I am just trying to discourage it.

The cable just had a thumb screw like thing on it and you could have it inside the camera case which is locked. Maybe you can lag it to the tree?
