I am now down to 30% and I do not get som many unwanted motion detections anymore. Once in a while, I get when it shifts from daylight to nightvision.
Additionaly, with 1.08 and and the updated myDlink lite app (for Android) I can now easily set detection level on motion and sound in the app. Thats a nice step forward. Previously I had to enter through the mydlink webportal and there is a lot of issues with certificate and java before it is possible to use the portal for this setup.
