问题: When checking the video playback, it prompts that " SD Card is not inserted"
回答:

1. Reinsert the memory card.

2. Replace with other memory cards.
3. If multiple attempts are made, it is still indicated that no memory card is inserted, but the memory card can be used normally on a computer or mobile phone. Please feedback the information such as the device ID and operation process to the customer service team.
