Alarms and its spare parts 4x4

The first documented case of car theft was in 1896, just ten years after the combustion engine was introduced in cars. Since the beginning of this era till today, cars are a natural target for thieves. In light of the dire statistical data that car is stolen every 20 seconds in the world, it is not surprising that millions of owners of cars and SUVs invest in Security Alarms.

Today, almost every car is equipped with an alarm, which consists of sophisticated electronic sensors, siren systems and remote activation and deactivation. Modern car alarms are a wonderful development, but thieves have found ways to get around this. New alarm systems for cars and vans consist of pressure sensors, noise and movement sensors. Sirens can have a many different sounds.

Extra battery allows car alarms to work even if the connection to the battery of the car or truck is broken. Ignition is the brain of the computer that controls all of these parts of the alarm. The key element of the car alarm is installed on the doors and hood. When you open the hood, trunk or any door, the computer triggers the alarm system.

Most car alarm systems use a switching mechanism already built into the doors. In modern cars, the system is connected to the interior light. Door sensors are highly effective, but they offer very limited protection. The idea of ​​shock sensor is very simple. If someone moves the car, sensors detect it and send a signal to the computer allowing the alarm to sound.

This sensor consists of three main elements: a central outlet in the body of the cylinder. Several smaller power outlets at the bottom of the hull and a little metal ball that can move freely inside the housing. Upon activation, the metal ball starts moving creating contact between electrical contacts. The most common detectors are glass breakage sensors, which is just a simple microphone connected to the computer of the car alarm.

Broken glass has its own distinctive sound frequency that the microphone detects. Thus, only that particular sound will trigger car alarms and other sounds are ignored. Sensors measure the air pressure in the car and when opening or closing a door or window, the pressure changes. From our site.
