The ATC-2000 Action Helmet Camera is a new activity camera for action oriented individuals. It shoots hands-free full color digital video in 640 x 480 VGA at 30fps. And as one would expect from an action cam, the ATC2k is both water and shock resistant.
Sadly it only supports SD cards, so there is no bluetooth synching for constant picture uploading via a phone, but I guess it is, at least, better than a lot of the other options out there. It runs on two AA batteries and connect to your computer with USB 2.0. The ATC2K is available now for $129.99.
