I had the same problem a couple years ago. I bought a cheap non-working camera off of ebay for about $10, then bought a stealthcam. I put the broken cam in plain sight, then used a ladder to put the stealthcam about 16' up in a tree aimed at the other camera. I busted the prick red handed. The thief was another member in my club. He was kicked out and the sheriff handcuffed and hauled him off while I watched. It was a sweet day. I hope I ruined his entire life.
