I have the same problem. Model E1 Pro. Solution is obvious and it's in the topic of this thread:
Disable motion detection events when switching between day/night modes
Disabling the motion detection for a few second(s) during day/night mode switching could solve this issue. It cannot be so difficult to implement. It's weird it's here for almost 4 years.
Workaround to disable general motion detection is not suitable for me. I want to have alarms for all motion detections, not only pets and humans. Alarm delay for general motion detection is not in settings. There is only delay for pets and humans and that does not solve the isue with general motion detection.
Before buying more cameras I need to answer: Is there a plan to solve this?
