How Long Can a Dash Cam Recordings Be Stored?
2 Answers
The storage duration of dash cam recordings depends on the capacity of the memory card and the set recording resolution. Generally, it can store recordings for about 3 days to a week. The larger the memory card, the longer the storage time. Taking 1080P quality as an example, a 16G memory card can record for about 100 minutes, a 32G card for 200 minutes, and a 64G card for 400 minutes. Additional Information: Dash Cam: The size of the memory card and the file format affect the recording time—the larger the capacity, the longer the recording time. Dash cams record in a loop. For instance, a C600 with an 8G card can record approximately 2 hours of video. When the storage is full, it automatically deletes the oldest recordings to continue recording, repeating this process.
My dashcam came with a 32GB memory card. Recording at 1080p HD resolution consumes about 4GB of space per hour, so the entire card can store roughly four and a half hours of footage. Since the device operates in loop recording mode, new videos continuously overwrite the oldest data, meaning most clips typically get erased within a day. However, during sudden incidents like severe collisions, the auto-lock feature protects those specific videos from deletion, preserving them for several months. To extend storage duration, I upgraded to a 64GB card. With double the capacity, it now stores over nine hours of footage – enough to cover my weekly commute. I recommend checking the card's status and formatting it monthly to prevent damage, plus manually backing up important clips to a computer or cloud for secure evidence preservation. Choosing a reliable brand also matters significantly.
