We are really interested to use the K2 for motorsport applications. There are several series now that require competitors to record their race so that any on-track incidents can be reviewed by officials. The main problem is with most cameras is, it's easy in the stressful conditions before a race to forget to turn the cameras ON! & batteries going flat! Unfortunately if an incident happens and they ask for your video and you don't have any you get penalized! The feature that is is powered externally and that it starts recording when you switch on is excellent. These races are often an hour long. I have read that your largest file is 10min. If a 10 min file is set does it immediately start recording another when the 10 min is reached or is there a gap in the video?
