Car alarms have integrated the latest technology into the car alarm system. So, how does it work?

Car alarm is an everyday occurrence; you just get to see it everyday. When an approximate of one car gets carnapped every 20 seconds, it is common occurrence indeed. Car alarms, in an effort to get ahead of car burglars, have integrated the latest affordable technology into the car alarm system. So, how does it work?

The first documented case of car theft was as early as 1896, only a decade after the Otto gasoline powered automobile was patented by Karl Benz of Germany. To combat this situation, car alarm systems are installed on automobile doors. So the first ever car alarm system was typically a car door alarm. But with todays cars, its much more sophisticated. Car alarm systems have sensors that go off every time a panel is opened; the panels can be the doors, the hood or the trunk. These sensors are actually voltage that travels around the vehicle including doors, trunk and hood. If this circuit is broken by forced opening of a panel or a voltage dropped due to interference with the electrical system, the alarm goes off.

Car windows are also one focal entry point for thieves. Most occasions they just bust the windows and hot rod the car; quite effective, too. New glass technology made it possible for glasses to withstand an amount of bashing. Glass reinforced with plastic is commonly use. One common window sensor is a breaking sound detector. The sound of breaking glass has its unique sound frequency that the system detects, and if triggered releases a full alarm siren.

Another car alarm feature is the shock sensor. The early models are two horizontal charged rods of metal which if the car is disturbed, will sway and touch each other completing the circuit and setting the car to alarm. There are difficulties with this though. Every time the car is disturbed, the alarm goes off no matter the cause. Slight disturbances like a slight weight shift from an individual leaning on the hood can cause full car alarm. Recent models are released, like Randall Woods shock sensor which, by its construction, is more falsealarm proof.

So concisely most modern car alarm systems include a range of pressure sensors that are electrical conduits all around the chassis that goes off when the circuit is severed. By opening a door or a trunk, the electricity is severed and full alarm goes off.  Car glasses are made more resistant to bashing. Also, the system includes a glassbreaking detector that goes off to the frequency of breaking glass.

Since 1896, car thievery was second to none most rampant thievery cases every year. Getaway vehicle, easy to break in, always in demand, and with a little bit of repainting can attract any interested buyer. But with the present state of the art technology, car alarm systems can stay up ahead with thievery.

Most victims of car theft never considered that it would happen to them. There is about one automobile stolen every twenty seconds in the United States alone. Even in today’s technology, car theft is very rampant. That is why car alarm system manufacturers are always improving their technology and innovating in order to avoid car theft.

Car alarm systems are gadgets that are installed on cars to thwart or discourage theft of cars. Car alarm systems of the early years work by making a loud sound and only. As the years go by, car alarm systems work by disabling the ignition system of the car. Some car alarm systems send a radio signal to the owner thru a beeper. Some car alarms are set off by vibrations, touch, tilting of the car opening or closing of door contacts, small and rapid changes in the voltage of the battery or through infrared sensors and ultrasound sensors.

In some cities in the United States, car alarm sounds are ignored because most of these alarms are accidental. They are either caused by vibration, thunder, passing of a large truck or of individuals innocently touching the car. And most people in some cities in the United States ignore or do nothing when they hear the sound of a car alarm. Because of large portion of car alarms are false alarms or accidental, car alarm system manufacturers are no longer producing simple noise making car alarm systems. As a replacement for these noise making car alarm systems, car alarm manufacturers are now producing silent “immobilizers”. Immobilizers are electronic devices that are installed on a vehicle that prevents the engine from running if the vehicle is inserted with the wrong key.  After the innovation of the immobilizers, sophisticated car alarm systems now feature “vehicle tracking system” that enables law enforcers to track stolen vehicles which is very much more effective than immobilizers. On the other hand, these advance features (immobilizers and vehicle tracking system) can not prevent theft of some articles or equipments inside the vehicle or vandalism of the automobile.

An ideal car alarm system must have the two above mentioned features and sensor that could detect vibrations and pressures of the car. Sensors like a shock sensors triggers the alarm when something or someone moves or hits the car. Some car alarm systems have loud alarms, concierge system, locking steering wheel system, cellular phone alarms that call the police, engine lock system and fuel lock system which prevents fuel from the engine.

Aside from car alarm systems, having a large and heavy gauged steering wheel lock is a good idea in preventing car theft because it will give the car thieves a hard and tiring fight just by removing it alone.
