Have tested for that, doesn't seem to be a problem. If it was I'd lower the sensitivity or turn it off. If something hit it like a branch say, it would go off. Exactly the same as a car-alarm. If it did go off, no harm done anyway as it shuts off after a while. Worst thing is some of the smarty-pants in the hangar tapping it every time they go past in an attempt to flatten my battery.
