I think that would be easy...
Detect if the camera chap has the camera(addon that he hold on the shoulder...)
Have a TV that you can use to wiew it, a script that give the TV an option to look on the camera, ie show him the internal wiew of the cameramans camera, with a mask on so it looks like TV...
Kinda like the sattelite script...
And, WHAT ABOUT a survelliance cam script?
And cam on plane, and Land Warrior, and so on...
