Problem with these cameras is mounting them. How do you plan to mount it to the car firmly so you have no vibration and eliminate wind noise with a mic built into the unit which is out in the air?
In my opinion, the only real good options for these cars are RaceOptics, VIO or ChaseCam. GoPro some people can make work but I have never seen a video yet from one with no vibration and/or wind noise. I feel the same for any of the all in one systems.
