ABSTRACT:
A programmable alarm and lot monitoring system monitors a plurality of individual vehicles congregated together in a given area. A central server transmits RF signals to individual RF transponder sensor units installed on respective individual vehicles and receives RF signals from the Rf transponder units. Each RF transponder unit senses a change in the status of the respective vehicle and, upon sensing a change, transmits an RF violation signal to the central server and also honks the horn, flashes the lights, and/or sounds an audible alarm. The central server may activate a remote video camera to record the scene of the violation, and if moved, follow the movement of the vehicle until out of camera range and transmit a violation message to a remote security station. In a global alarm mode, all of the individual RF transponder units honk the horn, flash the lights, and/or sound the alarm on all of the vehicles upon one of the units sensing a violation. Each RF transponder unit may be programmed to disconnect the battery of the vehicle upon sensing a violation, and to sense the vehicle battery voltage and notify the central server of the vehicle having a weak battery. In a vehicle locate mode selected RF transponder units flash the lights, honk the horn, or sound an alarm upon receiving a signal from the central server so that a particular vehicle may be easily located out of a group of vehicles. The RF transponder units may be polled by the central server at selective times to determine which vehicles are in inventory and which are not.
