I got a 1080p HD helmet cam from Drift Innovation for Christmas. It came with several attachment options and mounts. I bought it for the Alaskapade! and took it out yesterday for a test drive. So far, I really like it. It has a rotating lens so it can be mounted on the side or the top of a helmet. The articulating mounts are nice in that they allow you to maintain level framing regardless of where or what angle the camera is mounted. Another great feature is the remote control that can be handlebar or wrist mounted for instant start/stop recording without fumbling for the right button while riding. There are Drift user forums on the Internet that offer techniques that I will be trying to reduce the wind noise and I haven't figured out the remote control zoom yet. I have plenty of time. I hit 110mph on the bridge, but had to dial it down because the local municipal revenue generation patrols hide out at the end of the bridge as you cross back into Dallas county.
This, along with my handlebar-mounted video camera will provide some great footage for my Alaskapade! documentary. Look here for occasional interesting videos (or at least what I consider interesting) between now and June. Here's a sample of my first ride.
