What the alarm companies are NOT telling you is that any kind of outdoor se=
nsors are going to be activated by every kind of motion you can think of. B=
lowing leaves, insects crawling on the face of the sensor, birds, branches =
moving in the wind ... and so on.=20

So,............ although there are sensors that are available for outside u=
se they are for large commercial installations, are very expensive and usua=
lly require a local guard response because of false alarms. The type of dev=
ices that are used for home installations are not designed to do what you w=
ant to do.

Don't use outdoor sensors.
