Auto Security Systems That Don't Annoy Your Neighbors

A typical car alarm operates on the principle that a thief does not red sports carwant to draw attention to his actions. Thus, auto alarm systems usually involve detecting motion or vibration and then emitting loud noises, such as sounding the car's horn. This approach is very old, having been developed around 1920, and though the systems to detect motion and make the alarm have changed over the years, they are basically no more sophisticated in their approach.

Not surprisingly, the effectiveness of these types of auto security systems has diminished over the years. As most alarms are set off inadvertently by the owner of the car, most people tend to ignore them. Several studies have shown that car alarms do not actually deter theft or reduce overall auto theft rates, especially in large urban areas.

Manufacturers have responded with several new types of silent auto security systems that use the latest technology.

One type of these new silent auto security alarm systems employs a special ignition key with an embedded microchip and an electronic device called an immobilizer. This device does exactly what its name implies. If the immobilizer detects that someone is attempting to start the car but does not detect the presence of the key, it simply cuts of the flow of fuel to the injectors, stalling the car. This technology originated in Europe, where it is now standard equipment on many cars. In the United States, after market kits can easily be installed in most cars.

Even more technologically advanced are security systems that use the global positioning system to be able to precisely identify where the vehicle is located. Basically, these systems consist of a GPS receiver and a cell phone. The owner of the car can then call a missing car to disable the system in the event of a theft. Alternatively, the system can simply track the vehicle's movements and relay this information back to the owner. Many car makers include some variations of a GPS based alarm in some models.

Finally, some auto security systems are based on two way pagers. Quite simply, these systems page the owner, who than can send a message back to the car to disable it. These systems usually provide some type of information as to what triggered the alarm. Some systems even provide an option of automatically notifying the authorities, providing this feature is supported by the local police force.

In summary, security systems for cars have come a long way. No longer do you have to use temperamental noisy systems that rely on disinterested bystanders to intervene on your behalf. These new silent systems offer more security for your vehicle, and do not annoy your neighbors if they are inadvertently activated.
