So after the attempt on my life this morning, I'm thinkg of getting a helmet cam (or actualy a handle bar cam, as I'm one of those none helmet wearing types) and the ATC 2000 seems to be the cam of choice for many around here. But since I will have it attached to the handle bars, how easy is it to unclip? Is it QR, with a mounting attached to the bike and it just clips in? What resolution is it best to record your rides in? And how much recording time do you get out of a 1GB or 2GB card at that rate? Asking this so I can judge if it's ok to live with a 1GB card or go for the 2GB Whats the battery life like? Other than these questions please feel free to tell me any other things I should know about using this cam. Thanks.
