Epic Action Video Cam
 

Earlier in this thread there is a link to Epic action video cam like what Louboyd is talking about. I don't know how it would stay pointing down range while you are peering thru a scope but the same company sells a bunch of different mounting devises to use in lots of senarios. The screw into a tree or wooden permanent tree stand would work for me.

Cameras on guns can be used in several ways.
1. Just to record what goes on in front of the gun while using the guns non-video sights.
2. Camera mounted on the firearm with an LCD screen mounted on the firearm too. With an IR illuminator this can also work as a night vision sight too.
3. Camera and display mounted on a helmet. Helmet may have an IR illuminator. Gun carries an IR illuminator and dot pointer. You need line of sight to the target, but the the gun does not have to be aligend with the eye to shoot.
4. Camera mounted on the firearm, Display mounted on the helmet (one eye overlay, possibly semi-transparent). The shooter sees what's in front of the camera. Shooter can aim around corners and reamain behind cover. The gun carries an IR illuminatar and (maybe) a dot pointer. It is difficult to maneuver in clutter if the only vision is though a camera not located near one's eye.

There are many variants of combinations of CCD, bolometer, and Intensifer technology. CCD's are by far the least expensive.

As to videos making you vomit, no one is forcing you to shoot deer or to watch. Tou probalby shouldn't show your dinner guests the videos right after you've served them veneson.
