I stumbled across the Tachyon biker cam and bought one for a dash cam in my truck and for use on the scoot. Nearly hands off. The power is plugged into the 12V dash plug and the video can record continuously. Here's the cool part - it records videos in 15 minute intervals and automatically overwrites the oldest file when the card becomes full. If you have an uneventful day, just let it overwrite older files. No problems. No hassles. No separate DVR with endless fussing. http://www.tachyoninc.com/bikercam.php I was hoping to find this same configuration in a camera with higher resolution and good low-light/night video but so far I'm not having any luck. Any of the other cams have the capability to operate like this? .
