How Many Days of Recording Can a Dash Cam Store?

[Nettie]

The number of days of recording a dash cam can store depends on the owner's driving time and recording method. Taking a 16GB memory card recording 1080P video as an example, in loop recording mode, the video can only be stored for a maximum of about 100 minutes. Currently, most dash cams on the market default to loop recording mode. In this mode, the recorded video is divided into segments of certain durations (such as 1 minute, 3 minutes, 5 minutes, or 10 minutes) and stored on the memory card. With loop recording enabled, a 16GB card can store approximately 0.069 days, a 32GB card 0.0138 days, and a 64GB card 0.277 days. Newer recordings will overwrite older ones. If loop recording mode is turned off, the video information on the dash cam will be permanently saved. However, once the storage is full, it will not continue recording new videos. With loop recording enabled, the storage duration varies depending on the memory card size and video quality. When the memory card is full, newly recorded videos will directly overwrite the oldest segments (those farthest from the current time). The advantage of this mechanism is that it prevents the dash cam from being unable to continue recording due to a full memory card.
