PROTECH’s accelerometer intrusion detection technology captures variations in movement of an object according to 3 axes, similar to smartphone technology, and compares them to a pre-set zero point. Accelerometers measure changes in gravitational pull, like a smart phone does when it reorients the screen when a user moves the device.

G-FENCE and G-WALL sensors can therefore make an entire fence panel sensitive to cuts, climbs or lifts based on intrusion-induced vibrations (not vibrations caused by wind) but rather changes in the axes.
