RE: IR Motion detection problem

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

How about insect activity?

We get large plagues of thrips (thunder flies) every year and they have a
knack of getting into the smallest gaps (<1mm). A couple of years ago
before I sealed all our IR sensors, they were tripping them by walking
directly on the sensor.
