RaceKeeper now has an SRF kit for data and video. The link is here: http://www.race-keeper.com/SFR_Kit. I use 3 cameras in my car (front, rear, feet) but one camera is sufficient. For examples, you can see my videos at http://youtube.com/viperfergy. It's a one-step process. Video is recorded to an SD card and you can play the fully formatted video and also look at lap data, speed, compare your laps with another racers laps, etc.
