I've been researching on the internet and experimenting for my radio control varmint control project I'm working on.
Anyway, you can get cheap wireless cameras, remove the IR filter, mount them to a rifle (or pistol) scope, and provide an infrared light source either with LED's or filters over a flashlight. Then get some heads up display glasses or video monitoring glasses. You can have a night vision capable gun that you can fire from cover. They also have IR laser sights that can only be seen with night vision equipment or IR cameras. What a way to cheat at paintball! Also would be great for home defense.
From that point add radio control pointing and a remote control trigger pull device and you're ready to be a threat to varmints or ???
Just thought this was interesting technology compared to a $500 night vision rifle scope.
