Car Alarm Systems
Car Alarms are usually the only thing that can keep your car safe. They are made to alarm you and everyone in range for possible stealing attempt.
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. It is made by a simple switch that is pushed by the door. When the door opens – the switch sets the wiring and the siren goes on. This is not a good way of making an alarm because when you get into the car the siren will go on and you will have to disable it manually. This is usually done via another switch. It has to be hidden and like that only you will be able to shut it off when you get into the car.
When we want to make a system that is more advanced we use the same components but we add some new. These components are in fact sensors and now I will tell you about some of the sensors that are used.
The shock sensor is used to supervise motions and vibrations. It sends different signals to the operational computer depending on the intensity of the motion or vibration. For example if someone knocks on the window of your car a signal for low intensive vibration will be sent to the computer and it will make the siren beep once. This will warn the thief that the car alarm is armed and will respond to possible assault. 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. This is done by measuring the air stressing intensity.
Another good way for protection is tilt/motion sensor. This is important because the thief can get parts from your car even without opening window or door. For example he can easily lift up your car. This will give him a way to steal parts without setting The Alarm. 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.
And in the end I want to tell you about one very interesting solution. This is a message that is recorded and played instead of a beep. It’s a simple warning that tells the intruder that the alarm is armed. The funny part is that in some level the thief will react like if the system is in fact intelligent. This happens because of the human brain that reacts to the voice. Even when the thief knows that it’s only a system an unconscious warning will still be there to tell him that something could go wrong.
