Car alarms are not the same as immobilizers, although they are both designed to put off a car theft, they operate in a slightly different way. An immobilizer doesn't have any audible and visual theft deterrence, and it doesn't require additional input from the driver. They operate by disabling a number of the vehicles circuits which stop the vehicle from being started and driven away.
Car alarms can be broken down into two categories:
* OEM Built into the vehicle at the factory
* Aftermarket Installed into the vehicle after the vehicle has been built and left the factory, by a car dealer, a car accessories store, or the car's new owner.

Remote car alarms mostly come equipped with an number of sensors along with immobilizers and often motion detectors as well.

Because most car alarms are accidentally triggered mostly because the sensore are setup too sensitive, people often ignore alarms when they go off.
