Best picks
SanDisk MAX Endurance is our top pick for frequent loop recording, while Samsung PRO Endurance and Kingston High Endurance are strong alternatives. Always follow your camera's capacity limit.
Quick answer
The best dash cam SD card is an endurance microSD card that matches the camera's supported capacity and speed requirements. SanDisk MAX Endurance is the strongest long-life choice on published endurance figures; Samsung PRO Endurance suits buyers wanting a widely available V30 option, while Kingston High Endurance is a straightforward surveillance-focused alternative.

Common questions
Use a genuine high-endurance microSD card designed for continuous rewriting, in a capacity and speed class explicitly supported by the camera.
Only when the camera manufacturer requires it. Higher-resolution or multi-channel systems often specify U3 or V30, while some Full HD cameras accept a lower class.
Follow the camera maker's maintenance instructions and use the camera's format function where recommended. Back up important clips before formatting.
The card may be unsupported, worn, counterfeit, incorrectly formatted or corrupted. Check the compatibility list, format as instructed and replace persistent failures with a genuine supported endurance card.
Do not assume it will work reliably. Stay within the manufacturer's stated maximum capacity and required file system.

The VIOFO A229 Pro 2CH is our broadest all-round choice for front-and-rear detail. Garmin Mini 3 suits a discreet setup, while Thinkware U3000 targets parking surveillance.
A wireless dash cam normally uses Wi-Fi or LTE to move footage or connect remotely. It still needs power, and a rear camera often still needs a cable.
Start with the view you need: front-only for simple evidence, front-and-rear for broader coverage, or parking mode for protection while stopped.
Mini 3 is the smallest choice; X110 adds GPS and a screen, X210 raises resolution, and X310 is the 4K touchscreen option.
