Ok, so here is a great example of a sensitivity issue.
The street at the end of my property is about 100 feet away. Maybe more.
My sensitivity is set to 5.
However, every time a vehicle is visible over the slight hill at the end of my property (in this case a garbage truck), the camera trips.
This camera is one that rarely trips to begin with. Ironically,I can walk out that back door you see at the corner and not trigger the camera (and I am not a little guy)
