I have set up two zones per camera: The “yard” and the “entry” which is directly in front of the door. Whenever someone is at the entry, I get a notification. Since I walk these paths myself, I have hundreds of test points. Apart from that, I’m happy to _always_ get a notification before the bell rings. And I never have to open the door before I know who is there.
The “yard” part, I review every week. Here, of course, I have no data to compare it to, so I cannot say if it’s missing anything.
So yes, I’m certain it misses nothing that’s important to me - is there someone at my door and who is it.
