Looking to take video on the sly, or start your own underground version of COPS? The Nightvision Flashlight Camcorder ($150) can help. Sporting an eight LED array, it's a highly functional flashlight, but hides a two-megapixel still/VGA video camera in its face, which also happens to have an eight-foot nightvision range for even more covert recording. A five hour Li-ion battery keeps things running, while your video is recorded to a microSD card tucked inside the chassis.
