How Long Can a Dash Cam Save Footage?
3 Answers
The storage duration of a dash cam depends on the memory card capacity and the set recording resolution. Generally, it can save footage for about 3 days to a week. The larger the memory card, the longer the storage time. Taking 1080P quality as an example, a 16GB memory card can typically record for 100 minutes, a 32GB card for 200 minutes, and a 64GB card for 400 minutes. Here is additional information: Dash Cam: The size of the memory card and the file storage format determine the recording time—the larger the capacity, the longer the recording time. Dash cams record in a loop. For instance, a C600 model with an 8GB card can store approximately 2 hours of video. Once the storage is full, it automatically deletes the oldest footage to continue recording, repeating this cycle.
I've been experimenting with various dash cams, and the key to retention time lies in memory card capacity and video settings. With my 128GB high-speed card recording 1080P HD video, it stores about 10 hours of footage. When loop recording is enabled, old files get overwritten, typically retaining about a week's worth. Increasing resolution to 4K drastically reduces storage time, possibly down to just half a day. Memory cards range from 16GB to 256GB, and I recommend at least 64GB to cover several days' needs. Opting for high-endurance SD cards can withstand frequent read/write cycles, extending overall lifespan. Lowering frame rates or using efficient compression formats saves space and prolongs retention. I suggest regularly backing up crucial clips to cloud or mobile storage to avoid overwriting accident evidence. Different brands' compression algorithms vary in space efficiency, so pay attention to bitrate settings when purchasing for optimal storage. Ultimately, pairing a large card with moderate resolution strikes the best balance.
I prioritize safety while driving, and the storage duration of the dashcam is crucial, typically around three to five days. I usually use a 64GB card to record full HD videos, storing two days' worth of content, with loop recording enabled to prevent the card from filling up. For added safety, I set the G-sensor to automatically lock collision clips to prevent deletion, ensuring critical events are preserved. During long trips, I download and back up the recordings to my phone every night. If the capacity is insufficient—for example, a 16GB card might only store half a day's footage—it’s essential to handle it promptly. I recommend opting for a high-capacity, high-speed card to reduce the risk of write errors and ensure evidence integrity. Regularly check the device status to confirm normal recording and avoid losing information at critical moments due to overwriting. When selecting a model, consider cloud storage functionality for greater reliability.
