Solution:

1. Select a suitable SD card. It is recommended to use a Brand Card with U1 level or higher. The maximum capacity is 32G.

2. Use the Windows operating system to format the SD card. DO NOT Select the “Format Option -- Quick Format” .

    (Embedded Linux system FAT32 format corresponds to W95 FAT32)

3. If it still cannot be used, it is recommended to use SDFormatterV4.0 tool to reformat.

    (Note: If the customer chooses a SD card lower than U1 level, it can be used if it is properly formatted as described above, but there is a hidden danger of incomplete data writing when taking pictures or complex scenes of image transmission, such as photo saving Incomplete, video blurred, etc.)
