In my camera HP f800x, it has an option is "AAC/DEC alert" which produces voice or beep when the car accelerates 20 km/h in one second when driving at speeds at 80km/h, or decelerates 30km/h in one second when driving at speeds under 50km/h after position determined by GPS. I know how it work but i really don't know what it work for ? Could you explain and show me example to understand ? I don't see any dangerous to alert.
