A transmitter and receiver units comprise the identification and control apparatus for a surveillance and anti theft system The IC2IDU is an electronic memory, programmable with a unique identification number corresponding to the vehicle to which it is attached, connected to a transmitter unit which transmits a continuous scrambled pulse containing the identification number. The receiver unit identifies the scrambled pulse as a digital number, compares it to the number stored in the memory/data base and either verifies the authenticity of the number or generates an alarm or message. The transmitter circuit is also able to be connected to a vehicle's controller network and to control the vehicle via the mobile telecommunications network by either causing a restriction or interruption to the flow of fuel to the engine or by causing a misfire in the ignition cycle. |
