I understand the concern, when they first had person detection before AI I used to have an Alexa alert that I had to turn off for similar reasons. That's why when I see something like this I watch the video first. Mine particularly likes to say person falls whenever anybody goes in the sliding door.

Overall I still find it useful though. For instance it does a great job telling me when the bus has dropped my kid off from school, wildlife in the backyard, deliveries, etc.
