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

The dash cam requires a 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. The default file partition format of the card may be incompatible with the dash cam, so you should format it in the device before first use. (Page 4)
