Explaining the Car Alarm System

Explaining the Car Alarm System

It is essential to mention that almost all modern-day cars come essentially equipped with car alarms or central locking. Moreover, the top variants don’t need any locking system due to the keyless entry feature. Hence, here’s a breakdown of the significant parts that contribute to the perfect functioning of a car alarm system:


  • A Loud Horn – The loud horns go off to make noise when the car alarm is compromised.

  • Multiple Sensors – The multiple sensors essentially make the core unit of the alarm that detects trouble around the car.

  • Receiver– The receiver controls the status of the alarm system.

  • Control Unit– The control unit is essentially the brain of the central locking system.

Basic Working

The fundamental purpose of a car lock or the car alarm Sydney system is to secure the vehicle when it is empty and locked. This is technically supported by multiple servers that send signals as soon as they detect trouble around the vicinity. To put it simply, the risks could mean anything, ranging from noise, glass shattering, lock picking, and towing. These signals are later triangulated to trigger the noise in the security system. This effectively makes the car theft-free.

Car Alarm System Sensors

There’s no denying that security sensors are an integral part of any car alarm system. The car alarms are the layer of defence that constantly runs in the absence of the driver to detect trouble. They essentially interact with their surroundings. Moreover, they contribute to establishing a link between the alarm and the surrounding vicinity.

Unlike the modern days, the earlier car would come without or with a single sensor which would only guarantee a fraction of what today’s car alarm Sydney system can provide. Here’s a detailed breakdown of the sensors that come equipped with modern cars.

Door Sensor

It could either be an old-tech or a next-gen car, and either car model would be skilfully developed with a door sensor.

The door sensors are one of the most common car sensors. Going by the name, it is installed on the car doors.

Supposedly, if the car door is accessed while the car alarm system is active, it will trigger the computer to turn on the alarm noise.

Microphone Sensor

It is essential to mention that stealing a car is possible by effectively breaking the window. This is where microphone sensors step into the picture. They have two ways of functioning to secure any vehicle.

If the area where the car is parked has no noise, it’ll catch even the slightest of sound occurring in the vicinity. This will effectively send signals to the computer to trigger the alarms ultimately.

When you are driving through a busy road, the alarm will record all the surroundings. Eventually, when there is a sudden spike, the computer is alerted to trigger the alarm

Proximity Sensor

There’s no denying that most premium cars of the modern generation come with pre-installed proximity sensors. Having this sensor will essentially help you to detect activities within a pre-decided perimeter

A proximity sensor typically remains inactive when the car is parked.

However, if there is any activity in the vicinity, it sends the signal to the computer for the eventual alarm trigger.

Shock or Impact Sensor

There’s no denying that every neighbourhood is filled with naughty children worldwide. This is where the shock or impact sensor comes to great help.

The sensor gets into action when somebody breaks the window glass, bangs the car, or gets hit when parked. Any of the three situations send signals to the computer to trigger the alarm.

The sensor triggers the alarm if a cracker is supposedly set to produce a shock wave from miles away.
