Same. People only mode definitely detects people, but it also detects cats walking in my yard, spiders making webs near the camera (attracted by the infrared at night), headlights being shined on my fence, my sprinklers watering my grass.
It’s definitely picking up a lot more motion than it should. What’s worse is I have the Ring Chime in my bedroom because I had a theft problem in my backyard at one point. I’m depending on this mode, but it keeps me awake half of the night.
Ring needs some type of “smart learning” feature that allows Ring users to submit feedback: “yep, confirmed a human” or “nope, not a human” so that the system can get better over time to my specific environment and conditions.
Hoping for some improvements soon!
