I have found that it doesn't matter what you do if there is a low life out there he will steal or destroy your stuff. I had a camera stolen so I made a theft proof mount so since they couldn't get it off the tree they shot it. They also stole two tripod stands & one hang on stand all in the same year. By the time you buy one of the chips that have been disscussed you have the price of another camera stuck into it. I have found out that locks only keep honest people from stealing.
I do have a couple old broken cameras that I was thinking of using as bait & mount a working IR camera way above to get a picture of the theif!
