According to the plans, it's ~40ft from that wall to the glass. Sunlight
isn't a possibility, but outside those windows is a parking lot, so
headlights are. Those windows will be tinted, so that could help. From
the wall to the parking spot would be over 50 feet.

Good call about the NE corner. The L shaped wall is a half wall going
about maybe 40 inches or so.

Is the ademco 998 a good all-around PIR?
