Hopefully this will help some users but I just bought a Eufy door bell 2K and have it wired and noticed the same intermittent motion detection. The following steps helped me in my specific case/setup and hopefully will work for other. My best guess is that the Eufy “Human” detection just flat out does not work, To find an acceptable experience for me. I did the following:
- Set the motion detection to “all”
- Reduce the detection sensitivity to it’s lowest setting.
- Create an activity zone that covers just enough of my porch and is high enough to catch a full person.
I still get the odd false positive from cars on occasion but at least get every person that comes to the door.
This clear is broken tho and Eufy needs to fix the human detection algorithms/coding.
