I'm looking for a dashcam that constantly records video, just like your home TV DVR. When an event happens (such as an impact or someone pressing a "capture" button), the dashcam dumps the last 30 seconds of video to a file and starts recording. The result is that when something happens, you have video beginning from 30 seconds before the event -- not just the event itself.
Most of the commercial dashcams / MVRs I've seen work this way. Are there any consumer models that operate like this?
