A car alarm system is a modern device installed on a car in an effort to deter theft of its car itself, its parts, or both. These alarms are now being used for other purposes as well, but most commonly as a safety device. Car alarms function by emitting high-pitched sound waves when the right conditions for activating it occur. A car alarm system usually involves two things: the alarm transmitter and a receiver.

The car alarm transmitter is what connects the alarm transmitter to the main system, and it is the unit that will be attached to the car’s dashboard. It has a small transmitter which emits a high frequency sound signal. This sound signals are then picked up by the receiver unit in the car’s dash. The sound is decoded by the receiver and interpreted by the alarm receiver. The signal is then sent to the central control station. From here, a trained technician will activate the alarm. If the sound waves are not received, the alarm will not activate.
In the recent past, a car alarm had to be manually operated. This was because the radio signals were not strong enough to be heard by people inside the vehicle, and most people who were inside the car would be unable to hear the signals. Today, however, car alarms are equipped with digital receivers that have been specially programmed for these needs. The signal is now loud enough to be heard by anyone in the car. It also has a microphone so that when it is being activated, someone inside the car can hear it, as long as they have a headset. Some car alarms also have a special alarm button that can be pressed if the car’s alarm system is not working properly. Most car alarms today, however, do not use this type of button at all.
