yup most alarms already have these built in its so if the car gets towed the alarm turns off .i guess you could have someone disable the built in sensor and rewire it so it goes off if the car is lifted the alarm goes off although seems kind of pointless as most people would just ignore a car being towed and the alarm going off . i think the money would be better spent on a car tracking device gps locater . no matter what you do to the car to immobilize it ,it wont work they just jack car up and put it on dolleys.umm if the car tilts more than a certain angle the alarm goes off, they have been used for a while
