[Hai-users] PIR Motion Problems

[TheSleuth]

The PIR's that I use have adjusted coverage.
I would adjust these away from the actual windows
to the floor and pathways.  You avoid the common
problems of drapes moving from the HVAC, sublight
reflections and whatever else.  Unless, of course, your
main intent is to prevent theft of the windows themselves.

Adjustment usually means opening the snap-shut case,
loosening a screw or two and moving the circuit board.
