Does the Xiaomi Smart Camera C300 installed memory card still need to purchase the cloud membership?

The camera SD card recorded video saved locally, this will have the risk of being taken out and causing video loss. The SD card is also subject to greater storage space limitations. The Xiaomi Home Secure is not subject to storage space limitations. It has been uploaded and saved to the cloud video, and will not cause video loss due to SD card damage.
Note:
You can use the Xiaomi Home Secure without an SD card.
