Have a look at the MotorSports Camera. It's an in-car dual view (front/ rear) camera, built for & used by road racers.
Besides the front & rear camera views, it features rear infra-red abilities, GPS, G-forces sensor, can make MP4's, snap shots, Google earth links to the streaming video, MPH, Audio and more!!!! There isn't another racing camera like it out there. No one offers these features...especially for only $300...
Records up to 12 hrs, stores everything in an SD Memory Card, keep analytics of different track set-ups, etc...
