I think I'd have a cam or 3 on the cabin, as well as inside. They won't get them all. Doors that open out also help, as mentioned. Steel doors in steel jams make a huge difference. I'm a Deputy, I've seen a few doors that were thief proof, but not many. In most cases, they'd just break a window then.
How close is the nearest neighbor? When I had a farm in KY, we were remote. My closest neighbor had a cabin about a half mile away. He rigged up a siren system. It was all 12V that run off of a battery under his front porch. He had strings tied to his doors, and a trip wire in the living room. The lines all clipped to a toggle switch that turned on a police style siren. We were at our camp site one day when my buddy and I heard it go off. We hopped on the ATV and when we got there, it was him. He forgot to throw the toggle before he went it. Pretty effective, though.
