How Long Can Dash Cam Audio Be Saved?
2 Answers
The duration for which dash cam audio can be saved depends on the storage card capacity and the set recording resolution. A 16GB memory card can record for approximately 100 minutes, a 32GB card for about 200 minutes, and a 64GB card for around 400 minutes. Below are specific details regarding dash cams: When purchasing a dash cam, pay attention to the following points: Stability: The stability of a dash cam is crucial. Ensure that the dash cam you purchase does not suffer from unstable footage due to quality issues. Resolution: The basic resolution of dash cams is generally above 2 megapixels. If the dash cam you choose has a resolution below 2 megapixels, the recorded images might appear unclear. Camera Angle: A too narrow shooting angle can lead to blind spots, affecting the comprehensiveness of the recording. The camera angle should ideally be above 100 degrees, with 140 and 160 degrees being the most common options available in the market today.
As a frequent long-distance driver, the duration of dashcam audio storage primarily depends on the memory card size and settings. Based on my experience, a standard 32GB card typically stores about 3-4 days of audio files before the system automatically overwrites old data. Audio quality also affects storage duration—higher quality files take up more space, resulting in shorter retention. After upgrading to a 128GB card, I can store 1-2 weeks of recordings, which feels much more practical. Regularly exporting files to a computer or cloud storage can extend retention. I recommend checking audio storage options in settings—some dashcams offer adjustable loop intervals to prolong storage time. Also, be mindful of privacy; I prefer enabling audio recording only while driving to avoid capturing private conversations. In summary, a high-capacity card is key, and combined with proper settings, it ensures reliable preservation of crucial evidence.
