@DerekNolan Totally understand! The way that the camera will sense if there is a person or not in People Only Mode isn’t looking for facing or something of this sort, but more objects that are the size of a human. Therefore, the camera seeing something like a tree branch moving may not set off the actual alert to your phone and would cancel the recording, but something large like a person or that bear on the unicycle, it should pick up. And if you do get that, I NEED to see it! 
Hope this helps clear it up, and if you enable it and give it a try, would love to hear your feedback on how it is for you!
