I put mine out two weeks ago, and just went out to check it for the first time yesterday. I just go out and swap memory cards so I'm not walking through the woods twice.
I bought one of the steel "bear boxes" for mine, and use a Masterlock Python rope lock for it. I realize they're easy to cut with a good bolt/lock cutter - but some casual dude walking through isn't going to get it.
Here's my first video off my trail camera - took a couple of the clips and put them together. The bucks are still in velvet here:
