Dashcam microSD Cards: Capacity, Speed and Endurance

Choose a genuine high-endurance card that meets the camera manufacturer's stated capacity and speed requirements. Compatibility with the exact model matters more than the largest headline specification.

That depends on resolution, channel count, bitrate, protected clips, and how much history you want before looping. Stay within the camera's documented capacity range.

The card may be unsupported, worn, counterfeit, corrupted, improperly formatted, or unable to sustain recording. Back up needed files, follow the manual's format process, and replace persistent failures.

Follow the camera maker's interval or prompts rather than a universal schedule. Formatting erases footage, so save important clips first.

It may work initially, but continuous overwrite and vehicle temperatures are demanding. A supported endurance-rated card is the more appropriate choice.
