Why did the app notify me when there is no obvious movement?
Why the LaView F1 camera sends motion alerts with no visible movement, and how to lower sensitivity.
The motion detection will work when there is light changing, bugs flying or others. As long as the camera detects this image is different from the last one, it will consider it as image changing and notify you.
If it is too sensitive for you, change the sensitivity to Low: go to the camera's setting page - Detection Alarm Settings - Alarm Sensitivity Level - set it as Low.
