Question about 70mai A800S

Yes, the dashcam can overwrite the memory card after recording. It supports loop recording, which automatically deletes older recordings and replaces them with new ones when the memory is full. It is also recommended to format the memory card regularly, approximately every fortnight, directly in the dashcam to maintain performance and reliability. This deletes all data on the card, which is why important files should be backed up beforehand. The dashcam uses standard microSD cards with at least 32 GB and U1 (UHS-1) rating or higher.
