The PhotoHunter details at Engadget

The PhotoHunter - Engadget - www.engadget.com ++ "the PhotoHunter, a silent, motion-activated infrared camera that you put up in a tree. Ostensibly it’s for just snapping pics of wildlife or trespassers, but apparently the real purpose is so hunters can keep track of what times of day or night animals tend to pass by."
