Today millions and billions of people are investing in car alarm system. The reason behind the increasing amount of investment in alarm system is that these days the carazoo.com has become a major issue. Most of the car thieves are mastering the art of stealing and revamping the cars to start off their own business of dealing in stolen cars.

Car alarm system is the best way to reduce the increasing crime and keep our new cars protected. It is a system loaded with sensors, sirens and signals that gives a warning alarm in case of car theft. The basic version of the car alarm system comprises of a switch on the driver’s door that is wired to the siren. If anyone opens the door, siren will start wailing.

As India is coming up with new and high tech cars, the anti theft alarm system is also getting sophisticated and better in all aspects.The latest Indian cars are equipped with modern anti theft systems comprising various kinds of sensors, siren, radio receivers, auxiliary battery and computer control unit with a sophisticated and more secured output. Different sensors loaded at different places detect the motion, touch and pressure on the car. Siren is used to yield sounds in case of car theft. Radio receiver helps in permitting wireless control and keeps the owner informed. Auxiliary battery works as a replacement if the original battery is not charged up or functional. Lastly, all these working and operations of the system is controlled and monitored by the computer control unit.

Sensors are powered controlled devices that receive and respond to a stimulus. In modern car alarm system, there are mainly five different types of sensors that respond to various different stimuli or actions based on which part of the car is targeted.

Following are some of the most common types of sensors loaded in modern car alarm system:

Car-Alarm Door Sensors

This is the basic sensor that responds when a car thief opens any door of the car. Immediately, the car owner gets a signal. The sensor is either connected to a siren or to the interior lights. When the thief opens a car, switching mechanism built in the car door transfer electricity to the interior lights and alerts the thief.

Car-Alarm Shock Sensors

Shock sensors help a great deal in deterring thieves and vandals. If a car thief hits or moves any car, these sensors send a signal based on the kinetic velocity of the car. If the car receives a shock and feels an unidentified change in the intensity of motion, a warning alarm beeps. In some cases these sensors are also linked to the fuel engines wherein after detecting a drastic change in the intensity of motion, fuel engine automatically stops supplying fuel to the engine.

Car-Alarm Window and Pressure Sensors

These sensors are the main detectors for detecting broken windows. If a car thief hits the window of the car and breaks it down, these sensors detect the sound or the air pressure of the car. These sensors are connected to a microphone which in turn monitors the air pressure and in case of any variants, the air pressure fluctuation converts to electric current which is send to main controlling unit. In this way, specific sound will trigger the alarm and keep the thief away.

Car-Alarm Motion and Tilt Sensors

These sensors become functional when a car thief tows and drags the car to a safe place. Such sensors comprise o perimeter scanners that monitor any tilt, lifting and even slight movement of the car. Through these scanners it is also easy to monitor all the activities within a predetermined perimeter of the car park. Once the motion is scanned, the radio transmitter sends signal that are reflected by the receiver monitors. Similarly, tilt detectors are series of mercury switches made up of two electrical wires and a ball of mercury. This series of switches conducts electricity. In case of any car tilt or lifting, these electrical wires change the flow of circulation and warn the thief.
