BUMP!
I've been experimenting with the PIR sensor on my 2332L's. It's amazing how variable it is, depending on location. (Or maybe it depends on the camera?) One of my cameras, which looks at my back yard, is spot-on perfect with PIR sensing. Almost no false positives -- maybe a few each day; no big deal -- and catches human movement everywhere in the field of view quite reliably, day or night.
A second camera, which watches a side gate to my yard, varies between being under sensitive -- it almost never sees me if I walk into the field after dark -- and over, with a few false positives each hour. Still usable overall, but barely.
And a third, which watches my front yard, basically senses motion constantly through the day, and maybe for 20 minutes each hour after dark. To be fair, there is more motion in this field generally than for the other two, with flowers and shrubs waving in the breeze, and shadows on the lawn. But nothing where the IR field should change. Too, the other two cameras both have those things at least somewhat, and handle them much better. This one is useless for motion sensing via the PIR.
(I'm trying out a new 2330L in a different location, and it behaves much like that third camera -- basically thinks it sees motion every minute during the day.)
It's unfortunate the results vary so much.
