Why is the daytime Xiaomi Smart Camera C300 monitoring screen black and white?

To resolve this issue, please check for the following information:
1. The Xiaomi Smart Camera C300 automatically enters night vision mode if ambient light dims;
2. The Xiaomi Smart Camera C300 has a manual mode switching function, check the Mi Home/Xiaomi Home APP's infrared night vision mode to always be on status, this state even if the light is very strong, the screen is still black and white.
