How Car Alarms Work
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.
