I found the best deterrent is to be poor (and look it!) in a rich neighborhood.
Whatever camera you put in, I think I would have a sign that says so.
My brother in law was using a game camera, and it wasn't bad, but blew threw memory and batteries pretty quickly. Apparently, there was a LOT of motion going on at night...critters, wind, you name it.
My latest plan is to move all my tools out of the garage and into a shed that doesn't open to the alley. They could still break in, but it would require bigger balls as I would have a clear view of them from my house doing it...as would my neighbor.
Nothing pisses me off more than theft, and tis the season for it to start. Reminds me to go change bulbs tonight.
