Question about turning an airsoft gun into a motion sensitive automatic sentry?

Question

I recently watched a video on SpikedHumor.com about a paintball gun with an electronic trigger which was hooked up to a camera, and a computer with from what i can gather a motion sensing script written in C+. I'd like to know if i'm going to go about doing the same with an airsoft gun, can i just take a camera that can hook up to a computer and run pixel based motion sensing software which is then connected to servos controlling the firing of the gun or do i need a motion sensing camera along with motion sensing software?

Answer 1

motions sensing software should work. what do you think is in a motion sensing camera?
