Just thinking out loud here...

A long time ago I used to install car stereo/alarm systems and I always urged customers to use a microwave sensor when installing a car alarm. I have always had great success with them, especially convertables. I installed one in a tractor trailer, and it covered the whole space which is pretty impressive.


How it works:

Im pretty sure the 4 wire 12 volt models are 2 wire sensor (switch), and 1 12+ and 1 12- input. I am not sure about the 3 wire.

So in theory, if one wanted to have their phone alert them when movement in their house happens, I am sure this wouldn't be that hard to do at all.
