Vehicle perimeter alert system
View Patent ↗A vehicle perimeter alert system and, more particularly, to a vehicle perimeter alert system which is capable of detecting, using a plurality of proximity sensors such as infrared sensors or radar sensors and a display unit, the approach of any unauthorized person to a vehicle, is disclosed. Video cameras may be associated with one or more of the proximity sensors to provide a visual image display to the user of the system.
1. A system for detecting an intrusion into a detection field surrounding a vehicle by detecting a change in the field caused by the presence of an intruder in the detection field, comprising:
a plurality of proximity sensors, each proximity sensor monitoring a monitoring area, wherein each proximity sensor produces a signal upon detecting motion within the monitoring area;
a computerized monitoring control unit that receives the signals produced by the proximity sensors;
one or more alarms under control of the computerized monitoring control unit; and
a visual and audio display unit housing the computerized monitoring control unit and the alarms;
wherein the plurality of proximity sensors is attached to the vehicle to provide 360° coverage of the vicinity of the vehicle,
wherein further a sole attachment of the system to the vehicle consists of the physical mounting of the proximity sensors, the one or more alarms and the visual and audio display unit on the vehicle and the wiring of the system to the 12V power source of the vehicle,
wherein further the system has no attachment, integration or communication with the computer or other data systems of the vehicle,
wherein further the sole attachment of the system to the wiring of the system to the 12V power source of the vehicle solely provides power to the system,
wherein the system has no control over the electrical system of the vehicle or any other device or system connected to the electrical system of the vehicle,
wherein further the system has no control over any locking and unlocking system of the vehicle; any illumination device or light of the vehicle; any alarm system of the vehicle; or any speaker or any audio system of the vehicle.
2. The system of claim 1 , wherein the alarms comprise a visual alarm, an audio alarm or combinations thereof.
3. The system of claim 2 , wherein the proximity sensors comprise passive infrared-based sensors.
4. The system of claim 3 , wherein one or more proximity sensors are housed in a housing external to the vehicle.
5. The system of claim 4 , wherein three proximity sensors are housed in a housing external to the vehicle.
6. The system of claim 4 , wherein the housing is attached to the roof of the vehicle.
7. The system of claim 4 , wherein two housings are attached to the roof of the vehicle.
8. The system of claim 4 , wherein the monitoring areas of adjacent proximity sensors overlap in coverage.
9. The system of claim 1 , wherein the vehicle comprises a car, a boat or a motorcycle.
10. The system of claim 9 , wherein the vehicle comprises a law enforcement car.
