How Long Can a Dash Cam Store Footage?
2 Answers
The duration a dash cam can store footage depends on the capacity of its memory card and the set recording resolution, typically ranging from around 3 days to a week. Generally, larger memory capacity allows for longer storage time. Below are some considerations when purchasing a dash cam: The stability of the dash cam is crucial. It's important to avoid purchasing a dash cam that may produce unstable footage due to quality issues. If the resolution is low, the recorded images may not be clear. Even if traffic situations are captured, unclear images can make identification difficult. A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. After installation, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents.
The recording duration of a dash cam primarily depends on the storage card capacity and video quality. For example, with a 32GB card recording at 1080p resolution, you can store approximately 7 to 8 hours of footage, as each minute's file size is roughly 7MB. However, at 4K resolution, the files are larger, reducing storage time to about 3 to 4 hours. The loop recording feature is crucial—it automatically overwrites old footage with new content, preventing the card from filling up and stopping recording. The speed class of the storage card also affects performance; Class 10 or UHS-I cards ensure stable recording without dropped frames. I've tested various brands myself—HD mode consumes significantly more space than SD mode, so regularly formatting the card to prevent errors is essential. Extended parking surveillance increases file volume, so frequently checking settings is necessary to ensure worry-free usage.
