What type and minimum capacity of memory card does the A810 Series Dash Cam require?

The dash cam requires a standard MicroSD card with a minimum capacity of 32GB and a rating of U3 (UHS-3) or above. A memory card is sold separately and must be installed before use. Using a high-quality card from a reputable vendor is strongly recommended, as low-quality cards may have mismatched read/write speeds or storage capacity. (Page 4)
