Has anyone ever put up game or trail cameras at a desert race to capture the action without having hours of footage to look through?
They're cheap but one of the biggest problems I see is that something has to be within 40' or so for them to start filming, and then there is probably a delay after that. If it worked they'd be cheap enough to put on the backside of jumps, etc.
There are also motion sensing boxes that activate a solenoid to push a button on a normal camera to do the same thing. I remember reading about an in-car video system that would record two minutes before and after a button press, a combination of the two might be great but more expensive and complicated.
