Will Arlo Security Light look at only animate objects or will it notify if wind blows a tree?

We have one of the security lights pointed towards our sidewalk and yard.  There is a small tree that is also in the line of sight.  Does the security light look at only animate objects or does it also notify if wind blows a tree?

It's a PIR device which detects ir... it can reflect from trees, leaves, etc
