Micro SD Cards for Dash Cams: What to Choose

Choose a high-endurance card with the speed class and capacity explicitly supported by the camera manufacturer. Avoid assuming that the largest card your phone accepts will work in a dash cam.

It depends on resolution, channels and how much history you want before loop recording overwrites old clips. Stay within the model's published maximum capacity.

The file system may be incompatible or corrupted, or the card may be worn. Save any needed footage, follow the camera's in-device formatting instructions and replace the card if errors return.

Only if it meets the camera maker's requirements, but a high-endurance card is designed for repeated video writing and is generally the safer match for continuous recording.
