Maybe I've got the wrong kind, then.  I've got three of them, all called
"infrared", all aimed at the ground nearby and with the sensitivity turned
way down.  The one nearest the driveway is turned down so far that I can
just about walk up and touch it before the light goes on.  But they all
trigger occasionally for no apparent reason, much more so when it's windy.
The one in the backyard will stay on almost continuously if there is a sheet
on the clothesline nearby.

The one on the front porch did get a lot better when I trimmed back the
Jasmine bush, though.
