thanks for the feedback! Actually smart mode still works even camera and viewer connect to different WiFi bands (2.4G/5G). As long as the internet gateway is the same, Alfred can know the viewer is entering/leaving the local area network. We know that we need to automate the motion detection on/off soon. Using geo data helps the accuracy. In next release we are going to add some more permission requests regarding location service. We hope we can make motion detection more easily to use soon!
