Buying Automated Car Alarms

What should you look for when you’re buying a car alarm with automated features? The answer depends on the type of features that you want and how much you’re willing to spend to have them. Car alarms with automated features have been developed to help reduce the number of car robberies. In the past a simple siren type car alarm was enough to scare off car thieves, but for the most part this type of alarm can be easily disabled by any car thief with experience. Once the siren sound of the alarm is disabled there is no other feature that will prevent the thief from driving away in your car.

The automated features of car alarms are quite diverse; individual sensor activated design models will send the driver of a vehicle an alert when a specific area of the car has been violated, for instance if a window is broken. There are other car alarms with the automated feature of notification and response; where the alarm system dials a predetermined telephone number with a specific code that the driver must enter that will either incapacitate the vehicle or notify the authorities.

Car Security Alarms

Have you ever wondered how your car security alarm works? Contrary to what you might think, car alarms are actually pretty simple devices – they’re just a set of sensors connected to a siren.

A car security alarm typically has six parts – a siren (the device responsible for making the noise) and five sensors (window, door, pressure s, shock, motion and tilt sensors). The simplest car security alarms work mechanically – if someone tries to force the door open, for example, the car door sensor sends a signal to the siren, which in turn makes loud sounds. The technology behind door sensors is actually the same technology used in your refrigerator. Notice how your refrigerator lights turn on when you open the door and turns off when you close it? Both technologies are actually simple circuit systems – when someone forces the car door open, the spring pushes the button open and closes the circuit, sending electricity the alarm and siren. Most car security alarms systems have very useful accessories such as a radio receiver for wireless control from a key, and backup batteries that allow alarms to work even when the main power source gives up. Most car security alarms have sirens that are capable of creating distinct sounds so that the owner can pick out a sound pattern and be able to tell if it is his or her car that’s sounding an alarm.
