SD Card Dash Cam Compatibility Guide

Use the type, capacity and speed class listed by the dash-cam manufacturer, ideally from its compatibility list. A high-endurance card designed for repeated video writing is the sensible default.

No. Unsupported capacity, inadequate write speed or the wrong file system can cause errors, freezes or gaps in footage.

The card may be incompatible, worn, corrupted or incorrectly formatted. Save accessible footage, follow the maker's formatting instructions and replace the card if errors return.

Loop recording normally overwrites the oldest unprotected clips when storage fills. Protected files may be treated differently, so move any important recording to another device.
