I have one of these:
I have a staircase that looks like this (its not that nice):
So Im wondering where would be the best place to position the PIR:
- Above the staircase on the ceiling, facing down towards both segments of the staircase.
- On the wall over the landing
I read the plastic cap has these lenses that increase detection angle. So does it allow for motion detection all around, 180 degrees? In that case either setting would be good, right?
