[IROC]

My experiments along these lines taught me a couple of things. First, vibration is your enemy. Rigidly mounting the camera is essential. I started off with an I/O Port camera mount and sold it due to the amount of vibration it allowed. I made my own bracket that mounts the camera directly to the crossbar of my roll bar and it is much better (but not nearly as adjustable).

Also, I think the main limitation with using a "home" 8mm camera is it's mass. Mounting it rigidly enough to stop the vibration is complicated by the mass of the camera. I assume that is one of the primary reasons that in-car cameras used by the big boys are so small and lightweight.

Sounds like you're enjoying some success, though. That's great. My in-car video ranges from "hey that looks great" to "uhh...I can't watch that anymore"...
