The people detection function frequently picks up snowflakes and rain drops. The notification goes off every 1-2 minutes, sends the notice, and records the event for up to 30 seconds. Customer support told me there’s nothing that can done to fix it. Makes no sense to me since the unit specifically states the camera has this function. It will pick up a person when the weather is good and the pan-follow function works in this case as well. Not really a security camera if it can’t discern a person from snow and rain. I have two of these and both have the same issue.
