I sure do, it's mounted to the top of my computer monitor and can observe my entire room while I'm at school. On average each filming is about seven hours. I don't do this for actual security reasons, of course (though it would be great to catch a robber in my room one of these days, for ID purposes). I mainly do this because it's cool to see what happens in my room while I'm gone. My cats come and go, continuously exchanging time on the bed. Sometimes I even catch a family member coming in just to play my guitar or look at my books.
Also ghosts.
