An audible car security system that sounds when it notices a possible break-in is a car alarm. These car alarms can make a noisy disturbance which can be very annoying and a lot of the time is ignored. There are a lot more technologically sophisticated vehicle security systems that are available.

Manufacturers have designed cutting edge technology to help reduce the billions of dollars of car theft reported annually. Using two-way communication devices, car security systems can alert you when your car's engine has been started. Some newer systems have sensors to detect glass breakage. Others can be activated remotely and can even arm themselves passively, without the owner needing to remember to set the alarm.

You won't hear an audible car alarm if you're not near your vehicle. If your car is stolen while you're on vacation, it may be many days before you know about it. Some car security systems will phone you or send you a text message if a break in occurs. A two-stage automatic car alarm can also tell you if the car's engine is running, if the car is in motion, or if the car is stationary and has just been bumped into by someone.

While the vehicle is moving you can use the automatic car alarm to turn off the fuel pump, this is an effective way of bringing the vehicle to a stop. However, if your car is on a tow truck this won't make any difference in stopping the theft from occurring. Many of today's new vehicles also come with GPS tracking, which allows you to know where the vehicle is at all times.

Preventing Car Jacking: Several models of vehicle security systems are now equipped with car jacking preventative mechanisms. These mechanisms allow you to turn off the supply of gas to the vehicle with the press of a button. Having this safety feature gives you options you would not otherwise have. The feature is generally activated by a switch that is near the seat belt release; when activated it shuts off the fuel supply and applies the brakes to stop the car. This features gives a person a good chance of preventing their car from being hijacked.

Frequently, these systems will alert the authorities in case of a car jacking. The majority of these systems are meant to notify the police in an expedient manner which is immeasurably important in emergency situations. Trying to catch a car thief who is attempting to steal your vehicle is quite dangerous. Your automatic car alarm will inform you via a phone call or a text message when something is amiss. You can then call the authorities and let them handle the situation, rather than putting yourself at risk.
