Hello  @nebupm 

Thank you for reaching us about the issue of the motion detection feature. 

Please check if you have enabled both Motion Detection and AI (Person) Detection? The Person Detection takes effect for the whole area while the activity zone is selectable on the Motion Detection. These two features will overlap if you have enabled both. 

Can you share some screenshots of the motion detection setup here?  Please also provide a clip video about the wrong notification via private message. We'd like to help you check it.
