I'm toying with the idea of mounting a motion sensor of some sort over certain exterior doors and windows. Even if I find a reasonably suitable sensor, I expect it would have a fair amount of false positives so it wouldn't be tied into the alarm so much as automating lights or some other preemptive warning. I've read thru the discussions on exterior detection so I'm on the fence as to this being a worthwhile endeavor, but I like the idea of discouraging anyone snooping around before they cause any damage.
Was thinking about something like an automatic door sensor, along the lines of this unit:

.. but perhaps aimed towards the door or window to reduce false positives. It outdoor rated and can be ceiling (soffit) mounted, but I think the PIR sensor is less than ideal outdoors.
1) Tell me why this is a bad idea
2) Any other suggestions for a sensor? (I'm familiar with dual tech exterior motion detectors, but the bulky form factor is not at all aesthetic.)
