THIS BREAKTHROUGH SENSOR IS A HI-TECH ACHIEVEMENT IN TWO-DIMENSIONAL MOVEMENT SENSING TECHNOLOGY. UNLIKE Primitive sensors that require your vehicle to be parked on a level surface, this new digital tilt sensor will adjust to any surface level, which IS TRULY A LEADING-EDGE, STATE-OF-THE-ART ELECTRONIC DEVICE. Even if you park your car on the steepest hill, the remarkable digital sensor will accurately respond to the first hint of tilting, motion, or any other tampering to reliably protect your vehicle better than any other sensor. The artificial intelligence electronics of your digital tilt sensor are continually self-adjusting so there is never any need for sensitivity adjustments and never any possibility of false alarms. The alarm will activate at as little as 1 degree of tilt.
