Yi Home Camera false alarms

Hi.I own a Yi Home Camera 1080. But I have the problem that the camera always gives false alarms . It seems like during night it continuously adjust something into the lens so it see a false movement every few minutes ( about every 4 or 5 minutes ).
Here a video:

so you can see what I mean.

This camera is impossible to use in this way.
Let me know please if you can help me in some way. Thank you very much.
