What to do if the microSD card is not recording videos or cannot automatically delete old videos when using the Xiaomi Smart Camera C700?

If the microSD card is not recording videos or cannot automatically delete old videos, please refer to the following steps:
1. Check whether the Xiaomi Smart Camera C700 firmware and the Mi Home/Xiaomi Home APP need updates;
2. Check whether the storage switch is turned off or that the recording mode is set to record only moving images;
3. Format the microSD card within the Mi Home/Xiaomi Home APP;
4. If the Mi Home/Xiaomi Home APP cannot format the microSD card, use a card reader to format it on a computer. After formatting, power off the camera and reinsert the microSD card;
5. If the microSD card cannot record videos, the issue can be related to the card itself. Try replacing it to see if the problem persists.
