Hi neighbors. There a few things to look at when you are experiencing these symptoms of inconsistent notifications. First, you’ll need to adjust your Motion Frequency. This will determine the dwell time that is set between motion events. You can learn about Motion Frequency here.
Also, you’ll want to make sure that your Doorbell is properly positioned. This Community post here has great information on optimizing your Doorbell Motion detection. You can also share an image of your Doorbell so the Community can offer insight on ways to help improve.
