My dad has this one
Bushnell Trail Sentry Camera 5.0 MP at the cottage and has caught some decent pictures of moose walking in front of the garage. I don't know what the storage capabilities are so if it is set up in a high traffic area get one that has expandable memory.
Going the cheap camcorder will not work due to battery life and memory! Hope this helps
