The GunCam

hmm, sig pack sized. and here the army version looks like something that one would use for professional video...

but then again, the military one could probably work as a long range scope, and do nightvision...

I forgot where I saw it (so excuse the vagueness) but I remember seeing a hunting scope with a built in digital camera. So you can get a picture of what you were about to shoot before you shot it. Pulling the trigger activated the shutter.

Extrapolate. Enjoy.

there it is.

I could see the potential of the smart scope on sniper rifles. No more unconfirmed kills. "Hell Sarge, you can see the bastard has a rifle and here is what he looks like with a third eye on this manual shuttered pic."
