ABSTRACT:
Sound, vibration and motion are sensed within a motor vehicle to detect glass breakage and unauthorized intrusion into the interior or passenger compartment of the vehicle. Sound and vibration sensing are used to detect glass breakage with motion detection by means of radar or microwaves being utilized for intrusion detection to provide reliable recurring entry detection. The system may be operated to activate the motion sensing only after glass breakage is detected to permit persons and pets to occupy a motor vehicle having a security sensor system which is fully armed. Numerical values are assigned to specific physical sounds and vibrations with the resulting totals being compared to a threshold to determine whether glass breakage has occurred.
