Garmin dashcams use voice control commands that start with OK Garmin, allowing drivers to save video, take a photo or start Travelapse without taking their hands off the wheel. The short beep is the device feedback that the command was heard and the current clip will be protected from being overwritten. Clips of the command and its beep have been shared online by drivers posting near misses and road incidents, turning a plain system tone into a recognisable cue for saved footage in edits and memes.
