FlashCam - Video Recording Flashlight
This flashlight is also a video camera, and while it's designed for police use, it definately has a nice sousveillance ring to it. It's super bright at 85,000 candle power and also can do night vision with infrared illumination. It comes standard with an LCD monitor, 2 hours of storage, and it can also take snapshots.
Unfortunately, like every other thing I talk about on igargoyle, this item is ridiclously expensive, but if you have 2.5k to play with, you too can own one.
