Alarm Systems for Cars

An Overview of the Popular Types of Alarm Systems for Cars

A car is a very important investment in a person's life, and hence, should be protected with the best alarm system. Since it is valuable, and easy to resell, it is a prime targets for thieves. The article enlightens you about alarm systems that will help protect your car.
The first case of car theft was recorded in 1896, a decade after gas-powered cars were introduced. Studies have claimed that nowadays a car gets broken into every 20 seconds in the United States alone. Therefore, to reduce this increasing crime, and to keep our cars protected, today almost every car is equipped with the most sophisticated security systems. Alarm systems for cars are loaded with sensors, sirens, and signals, that generate a warning alarm in case of car theft. The basic version of the alarm consists of a switch on the driver's door which is wired to the siren so that if anyone tries to open the door, the siren goes off.

Today's modern cars are equipped with alarm systems that are more advanced and developed. They comprise:
  • A layout of sensors which include switches, pressure sensors, and motion detectors. Sensors are basically devices that receive and respond to a stimulus.
  • A siren to generate a variety of sounds so that you can choose a distinct sound for your car.
  • A radio receiver that permits a wireless control from a key fob and keeps the owner informed.
  • An auxiliary battery that can be used as a replacement if the original battery doesn't work or is not charged.
  • A computer-controlled system to monitor and control all these operations of the system.
Door Sensors
Door sensors form one of the most basic alarms available. These immediately respond when a thief tries to open the car door. The sensor is attached either to a siren or to the car's interior lights. Most alarm systems employ a switching mechanism built within the car. As soon as the thief opens the door, the car door transfers the electricity to the interior lights and alarms the thief.

Shock Sensors
Shock sensors are advanced alarm systems that help in deterring thieves and vandals. These function on a simple principle, in which when a thief hits or moves the car, the sensor sends a signal as per the intensity of car motion. So, if the car receives a shock and experiences an unidentified change in its velocity, a full scale warning alarm beeps. In some cases, the sensor is also connected to the fuel engine which stops supplying fuel, if a drastic change in the intensity of motion is detected.

Window and Pressure Sensors
These sensors are very effective in detecting broken windows. They are connected to a microphone which is attached to the computer-controlled system. When the thief breaks the windows of a car, the sensor detects the sound and air pressure of the car. The microphone monitors the air pressure and air fluctuations, converts them into electric signals, and sends to the system. This way it triggers the siren and alarms the thief.

Motion and Tilt Sensors
These are extremely helpful when the thief tries to tow or drag the car to some other place. The sensor consists of perimeter scanners that tab any tilt, lifting, and even slight movement of the car. Like this, one can easily monitor all the activities happening within a predetermined perimeter of the parking lot. Therefore, if any motion is scanned, the radio transmitter transmits signals which are reflected by the receiver monitors. Tilt sensor consists of a series of mercury switches formed by two electrical wires and a ball of mercury. These switches generate electricity and in case of any car tilt or lifting, the electrical wires change the flow of circulation and alert the thief.

All these alarm systems for cars are highly efficient in protecting cars from thieves, and will also help in maintaining car safety. While choosing an alarm, make sure it has a loud and effective siren or alarm, else it won't be able to deter thieves. In fact, nowadays many car security systems play recorded messages when somebody steps too close to the car.
