There is actually 2 sensors, 1 passenger side front and 1 drivers side load space, above the side window. They communicate with each other when the alarm is activated. The alarm ecu compares data from each and if they both correspond , off goes the noise!
And yes pretty sensitive , any air movement , such as from an open sunroof will trigger them. They are volumetric sensors, not movement sensors as such , they use air displacement means. If you tape the window cover so no wind enters should be oki.
