Well when I saw your post yesterday I almost replied that my cams do respond at about 40’ away, but they were V2’s.
So I set up my Pan-cam looking down my driveway at the street where cars drive by USUALLY less than 20MPH (I’m on a deadend court about 70’ from the end).
I’ve been getting alarms all morning,
Pictures for distance reference here:
Truck is a least 12 away from camera and is 20’ long.
