nuideas1, I have a method that works pretty good but you'll need 2 cameras. I know that sounds expensive but it's not as expensive as losing one camera!
I pick my spot and set up my camera. I use a cable lock on that camera just to discourage any would be thieves. I then use a cheaper camera and point it to the original camera! I place the second camera high enough in a tree that no one will see it. If someone steals the first camera, you'll know who did it! It works well and I know of at least one person who got caught. Stealing a trail camera is a felony in most states because of the cost of the camera. If you make an example out of one person, word travels fast!
Another alternative is to buy a satellite camera, one that sends you pictures in real time to your email. You would then get the picture before they had a chance to steal the camera. These cameras are pretty expensive though, so you may want to try the first strategy first.
I hope that helps!
