How Car Alarms Work
Car alarms are an electronic device which is designed to prevent burglary and warn
the owner if a theft attempt is being made. Usually a car alarm will output a high
pitched sound when the system is triggered by vibration, close or open of trigger
switches, sensing of small and fast change in battery voltage. Today's car alarm
also monitors sensors like infrared, microwave, ultrasound or tilting of the vehicle
in case of unauthorized towing. Some cars have alarm systems which send out SOS
signal in case of breakdown or theft. Alarm systems are also incorporated with navigation
system to increase the security of the car. If the car is stolen, it can be traced
by an embedded navigation system. This functionality can also be used to locate
lost cars in large parking lots by giving out a chirping sound.

Many times a car alarm can give out a false alarm when it feels vibrations of thunder
or a passing truck. Sensors need to be adjusted properly otherwise it can trigger
the device even when a person accidentally touches the automobile. There is an increase
in the crimes related to theft of vehicles. For people who want security for their
cars and want to avoid false alarms you can have a police tracking system installed,
many newer cars have this tracking capability built in to the operation of the help/navigation
system, like On Star. This system comes with an additional cost which is to be paid
on a regular basis. Most alarm systems utilize a remote controller (key fob); this
way a user can disable the alarm from a distance. The remote control feature is
very convenient if the system is triggered by a false alarm. Key fob's can integrate
a variety of functions, controllers that have the LCD option which can project the
image of the part of the vehicle that is under threat by a thief is one example.
