Grand auto theft is the largest area of organized crime growth outside of the drug trade. This crime has been with us since 1896 when the first incident was recorded. Stolen cars are extremely difficult to recover because of the time limit and the scale of the criminal processing industry. In the average time, that it takes for the local police to alert their patrols after a car theft, a car is stripped for parts or repainted and sold. It is a hard fact that the best way to stop this growing trend is through modern car alarm systems.
THE WAY A MODERN CAR ALARM WORKS
One of the best is the viper car alarm in America and the Clifford alarm system in Great Britain . These systems employ extremely sophisticated devices and concepts. A generalized description of them will give you an idea of their efficiency. The sensors used in the automotive car alarm system involve sonic, air pressure, closed electrical circuits and mercury motion/shock sensors. The sonic and the air pressure sensors are used under two circumstances. They detect and alarm when the windshield is shattered after the car is armed and when the door circuits are bypassed. The sonic and air pressure sensors detect personal presence within the automobile after the car is alarmed. The armed and unarmed status is initiated through the radio receiver, which responds to the wireless signal of the keycode transmitter. The message is passed from the receiver to the car alarm computer control unit, which logically processes the armed or unarmed message. The computer control unit determines the events, which constitute a break-in or attempted vandalism. These sensors can detect the opening of a door, the engine compartment and the trunk or boot. They can sense the presence of a person within eighteen inches of the car. This can be processed and a car alarm siren with a verbal warning can be announced. If a highjacking of an automobile is attempted by a forklift or a cargo net then the mercury motion sensors will set off a car alarm siren and flashing lights. Additional sensors are fire detection in the engine compartment and the LOJACK, a geographical orbital positioning system detector and tracker device. This sensor has shown promise in tracking the position of a stolen automobile within two-six hours, which is the estimated time taken to discover and remove this sensor. It is highly recommended that a hidden auxiliary battery be installed for the car alarm system. Another feature that I find extremely important is the remote ignition and light system. The newest car alarms have a two-way pager, which alerts you to alarms, attempted entry and engine fires. Maybe they will provide a robotic drive system as shown in "Batman" in the future, whereby you can remotely drive your car to your location, a person can hope!
Before you purchase your car alarm system, you should read the available car alarm reviews in the automobile magazines and on the internet. This is essential to know what car alarms are available and to take advantage of the best prices.
