Car Security Alarm Sounds

Car security alarm sounds will make your car safer everyday

An early version of a car alarm for use as a theft deterrent was invented by an unknown prisoner from Denver in 1913. This version was manually armed, and triggered when someone tried to crank the engine. A later alarm inspired by an early version of a remote starter was published in 1916. This version had the car owner carry a receiver, which would buzz if the car ignition system was tampered with.

A car alarm is an electronic device installed in a vehicle in an attempt to discourage theft of the vehicle itself, its contents, or both. Car alarms work by emitting high-volume sound (often a vehicle-mounted siren, klaxon, pre-recorded verbal warning, the vehicle's own horn, or a combination of these) when the conditions necessary for triggering it are met. Such alarms may also cause the vehicle's headlights to flash, may notify the car's owner of the incident via a paging system, and may interrupt one or more electrical circuits necessary for the car to start. Although inexpensive to acquire and install, the effectiveness of such devices in deterring vehicle burglary or theft when their only effect is to emit sound appears to be negligible.
