That is most likely due to the implementation of microwave motion
detectors that can be placed in a rather sneaky fashion, since they
will shoot through solid objects. 

One company kept getting calls to a warehouse to fix false alarms, until
it was discovered that the unit was picking up passing trains outside.

They rehung the unit.

I like infrared myself, microwave is good if you want to cover several
stories or areas regardless of walls in the way.

Sonics tend to create falses due to movement of fan blades, phones that
ring in harmonic range of the detector, and cob-web spiders building
nests in the recievers.

I usually think about how I would break in, and then spend my time
laying traps and misinformation for the would be theives.

In this way you force them to do something that causes their demise.

--such philosophy is another story   ;-)
