In the dark environment, YI Home Camera will enable night vision mode automatically. If you face your camera towards out of the window, the window will reflect the infrared light, and then you may not watch the video clearly.
However, you can switch off the IR light through the app manually.
1) Open the app, and enter the video page
2) Press the setting
3) Press “settings” under the “basic” tab
4) Then you can switch on/off the IR light manually
