Two questions really, what numbers do you guys have your G-sensor sensitiivty on.
And also, I was thinking, lets say you have a close call and you do press the emergency button, does that file get put to a side so it doesn't get overwritten or something ?
I changed the sensitivity on my RH to the minimum as it was always triggering an 'event', so I bought a 16gb SD card and have it constantly recording. I think you may be right a triggered event will be marked so it won't be overwritten.
