How can a dashcam possibly detect an accident? Wouldn't that basically start recording after the fact and hence be mostly worthless?

- detaro 7y agoNo, they are allowed to have a buffer of last X minutes.
- oh_sigh 7y agoAccelerometers. How it works is there is something like a 5 minute, constantly overwriting video file. Once the accelerometers detects an abrupt deceleration, it determines an accident occurred and marks the previous 5 minute segment of video as read-only.
- romwell 7y agoThe dashcam will record into a, say, 5-minute buffer until the accelerometer registers a high value, at which point it starts writing into a new file (so the buffer becomes a permanent record of the 5 minutes prior to the incident). That's one way to implement it, one can come up with many others.

- Scoundreller 7y agoDunno how well this will work if you need to claim that the pedestrian or cyclist just darted in front of you. But then again, maybe you don't want that kind of thing recorded.
- waisbrot 7y agoYes, if you hit a pedestrian and didn't brake, dash-cam footage of that would not be helpful to your court case.
- gtirloni 7y agoActually, the lack of a permanent recording (barring technical issues easily identified by forensics) would be very helpful... to the person you hit.
- zaarn 7y agoThere is almost always a button for manually triggering a recording.
- Scoundreller 7y agoIs that legal in Austria?
- zaarn 7y agoShouldn't be any more illegal than recording something with your cellphone (when not in the car) that you are interested with. I'm not quite certain about the legal code in australia but private recordings should generally be exempt from a lot of things.
