I have jumped far down in sensitivity (all the way from 9 down to 1 going one setting at a time) and tested and tested to get some form of consistency from the cameras.
I’ve tried different angles too and when the camera does go off, the object that set it off is not even in camera frame (e.g. very top or very bottom of the capture). You can just see the edge of movement to note what might have set it off. Anything in frame is very delayed and is only partially caught.
Example one - someone pulls into my drive way (well in view) and nothing happens. They get out, walk around their car and come all the way to the front door. Just as they get to the door, that is when it goes off.
I have had someone come from the street all the way to the door and just slightly out of view (bottom half) the camera gets activated.
Batteries have been new or used - even when camera states batteries are good.
Wifi > camera to wifi is full strength (5)> camera to sync is just one bar down (4)
I have other views too, but this is the wanted view as others may not catch enough area.
