A tamper-proof motion and tampering alarm for a pneumatic tired vehicle consists of a motion detector, tampering detectors, radio transmitter, and power supply. All of these are mounted inside the pressurized tire of the vehicle. Any unauthorized motion or tampering with the tire will cause the alarm to be activated at a distant remote site by way of radio signal through the dielectric tire. The control unit consists of a radio receiver, alarm, system interfaces, and power supply. The system can be enabled and securely disenabled by use of prearranged and encrypted radio signals. |
