Why the SD card can not be recorded automatically?

· Since the high-definition video data is large, when the video is recorded and stored, each frame of data is stored in the memory card. If use a low-speed card for storage, the storage speed and the video required for the video recording will appear. It is recommended that users use C10 or above high-speed memory card.

· Check if the memory is full and cannot be recorded, and if so, please format the memory card.
