Car Alarms

Modern car alarms consist of pressure sensors and motion detectors. When activated, they set off a siren that is capable of creating a variety of sounds. A radio receiver allows wireless control of your car alarm from your car keys for a remote start. The system is controlled by battery. For this reason, all car alarm systems have an auxiliary battery so that the alarm can operate even if the main battery gets disconnected. A computer control unit, called the "brain" of the alarm system, monitors the car and sounds the alarm when it senses inappropriate motion.

Th door alarm used to be the most popular alarm form. However, car thieves have grown more sophisticated. They don't need to open your car door in order to steal your car. They can break the glass or tow it away. Auto security systems have had to get tougher as the criminals get smarter. Industry standards like Viper car alarms have taken these sorts of problems into consideration.

Modern high-end alarm systems depend on shock sensors to deter thieves. If somebody hits or moves your car, the sensor contacts the brain and reports on the intensity of the motion. The volume of the alarm depends on the intensity of the motion. A slight jostle will signal a warning beep, a more aggressive movement will trigger an all-out alarm.

Unfortunately, this system is not always accurate. As anyone who lives in a large city can attest to, there are many false alarms that result from over-zealous sensors. As a result, new forms of sensors have been created. Window sensors set off the alarm if the glass is broken. Pressure sensors can monitor air pressure levels to detect an intruder. Perimeter scanners monitor what is going on around your car. Tilt detectors protect your car from thieves with tow trucks. In order to determine which of these features you need in a car alarm, you should first consider how you use your car. Are your valuables kept in your trunk? Do you travel alone at night? Is your car parked on a city street? If so, you may want a system with a car remote starter.
