Executive Summary By Kalin Staikov

Car alarms are usually the only thing that can keep your car safe.
We will go over the most frequently used car alarm systems and how in fact they work. To begin let’s see one basic system. It needs only three components – siren, wiring and a door sensor. This sensor is made to put the siren on if the door is open. When the door opens – the switch sets the wiring and the siren goes on.

The shock sensor is used to supervise motions and vibrations. If someone tries to break the window the sensor will signal the computer and a full-scaled alarm will go on.

The pressure sensor is another good part of the advanced car alarm systems. It can detect both breaking or opened window and open door. For example he can easily lift up your car. To prevent this some alarms uses scanning devices that can tell if someone gets close to the car. This is usually done by radar system that checks the signal reflection immediately close to the car.
