Re: Problem With ADT System - Need Advice

What might be adding an extra measure of insensitivity to your setup is
the fact that the motion is so high up on the wall, and when you move
in front of it, you are at quite a distance away from the device. So
it's still sensitive to your body mass, but a small cat at that
distance doesn't register much.

I swear, sometimes I think making pet motions work reliably is one
quarter science, one quarter art, one quarter luck and the other
quarter just plain magic.....:)))
