Doorbell 4

I have a good WIFI connection, however, all images are fuzzy at the start and become clear just before the video ends. Don't know why. Doorbell 4 - Not all events (the important ones - people coming in and leaving the house) are recorded. Don't know why. Sometimes it will record and then not at other times. Tried to follow the advice given on https://support.ring.com/hc/en-gb/articles/360022461232-Motion-detection-for-Ring-devices-FAQ#:~:text=Try%20adjusting%20your%20motion%20zones,person%2C%20other%20motion%20or%20package. but that is useless. Ring Doorbell 4 Pro doesn't seem to have the same functions ie. "People Only Mode" This is annoying. There are a few features on the Ring Video that mine doesn't seem to have. can anyone advise? Thanks
