How to Choose a Micro Card for Your Dash Cam

Treat the camera manual as the compatibility list. The right card must sustain video writing and stay within the supported capacity range.

The correct micro card for dash cam use is normally a microSD card rated for the camera's recording load. Packaging language can be confusing, so match the microSD, microSDHC or microSDXC format and supported capacity to the manual rather than choosing by size alone.

Common questions

Questions before you buy

What type of micro card goes in a dash cam?

Most use microSD, but the supported capacity family and speed class vary. The slot label and exact model manual provide the controlling specification.

Will an ordinary phone memory card work in a dash cam?

It may meet the raw format requirement, yet continuous video can wear general-purpose cards quickly. Use an approved or high-endurance model where the manufacturer recommends one.

How much footage fits on a dash cam card?

That depends on resolution, codec, bitrate, channel count and protected files. Use the camera maker's recording-time table rather than a generic estimate.

Why has my dash cam stopped overwriting old clips?

Protected event files can consume space, or the card may be corrupted, worn or incorrectly formatted. Save evidence, then follow the manual's maintenance steps.
