DETERRING CAR THIEVES
THE SOUND OF CAR ALARMS GOING OFF AT THE TOUCH ARE COMMON ENOUGH. HOW DO THESE CAR PROTECTION SYSTEMS DETECT INTRUSION?
In a car alarm system, a siren is connected to a few sensors to ensure that as soon as a person opens a door, a signal is transmitted to the wailer from the sensor. Current car alarms are more sophisticated in terms of how they function and the safety features they come with. There are components or devices like radio receivers, motion detectors, pressure sensors, auxiliary batteries, etc, that enable the alarm to function efficiently, even if the main battery of the car fails.
The main part of the alarm system called the brain, a computer control unit, is designed and used to monitor everything that happens regarding the alarm. It triggers the alarm when required. It is connected to all the sensors that are installed in a car.
Most car alarm systems come with some sort of portable keychain transmitter. With this device, we can send instructions to the brain to control the alarm system remotely. This works in basically the same way as radio-controlled toys.
Sophisticated modern-day sensor alarm systems make use of shock sensors to ensure that thieves return empty handed. Shock sensor alarms run on the concept of motion strength. Signals to the brain of the system by the sensors determine the strength of the motion and can detect whether someone is trying to push or move the car. The brain of the system immediately gets the horn honking or activates the audio system to start playing loudly in order to ward off the unwanted person/thief.
