how can you dirve by camcorder?

one time I BUILD a special turret with two servo installed to control the elevation and focus change. but I CAN not hook it to transmitter, so I can change the view or focus.
I built that turret for Danville battle day, sold it to one gentlemen in UK after I realize I will probably not go in a while. I even painted a red cross at the rear to avoid enemy and friend fire. I called it reporter turret.
