Theft is always a concern. With the price of cell cams coming way down, that is all I'm running now. Got 12 of them out, all on state land. I feel like cell cams are less likely to get stolen due to the fact that there's a good chance i will get a picture of the would be thief. And if they redeploy the cam, the pics will come to my phone anyways. My 4 newest cameras also show GPS location, so if a thief turns it on in his home, I will have his address haha. And there's the fact that you can put these right in your hunting spots without ruining them with scent from checking the cams. I'm running the spypoint cams and have been happy with them so far.
