Actually i was considering one, I might get one.
Doesn't take a expensive one but they have them. If I could afford it I would get one of the black light ones, can't be seen by people at night, the others are infrared like I have, not super noticeable but do show a bit of a red glow of led's at night, super quick in pic mode, longer in vid. They also have some that email you pics as they happen.
I bought mine originally to scout for deer, hunting purposes, have lots of pics of deer, some of bear, some really scary one's of a fisher, didn't even know we had them (only scary cause of my chickens, was pretty cool otherwise).
I mainly use it for chicken coop scout now, see what's out there, had a couple coyotes on it. Also have hid and used it for a security cam, pointed at our house and driveway when we leave for vacation, we're very rural and doubt any probs, don't even lock garage, but it makes me feel better if something does come missing, don't have to wonder and suspect.
Couple pics on my small coop, so you can see what it's capable of, just a cheap $50, 6 megapixel I bought five or more yrs ago, they are a lot better now and more megapixel at that price.
Did not have any probs with that fox, must have had easier things to eat.
