Depends. There are several different style. You can go like Novritch and make a mount for a video camera, you can get a Mobius Action Cam and replace the lens with a 7-8x zoom (make sure you get an IR filter or everything will look purple), or you can get a scope that records video (usually rather expensive). I have a mobius with an 8x zoom that I use on my AEGs and such, and I have an ATN X-Sight HD II for my VSR that records rather well (but it costs $750).I would say go with a mobius unless you want a one piece system.
