Why Does Your Car Need An Alarm?

Why Does Your Car Need An Alarm

Auto-theft or carnapping is one of the most common crimes in the world. In the United States alone, a vehicle is being stolen every 33 seconds. According to the Federal Bureau of Investigation, out of all stolen vehicles, only 57% were recovered. On the other hand, annual cost of stolen cars surge up to 7 billion US dollars.

Wild kids in the neighborhood seeking excitement and thrill were one of the identified car thieves, and this group is the chief one connected to the recovered vehicles.

The other groups of car thieves, however, are more disturbing: they are composed of sophisticated criminals adept at stealing and stripping car parts and selling those in the black market in various parts of the country.

Other vehicles, conversely, were shipped overseas and sold abroad. This explains the remaining 43% that were never recovered.

How Do Car Alarms Work?

How Do Car Alarms Work

In choosing the right car alarm for your car, basic knowledge about the device is essential. Car alarms are primarily manufactured to prevent theft, and this is achieved by scaring the prospective criminals and making your car inoperable – and this is where car alarms serve their fundamental function.

Okay, first thing first. Car alarms are chiefly composed of three basic components:

  • At least one sensor
  • A siren that creates noise as well as flashes light in times of intrusion
  • A control unit

So you can make them all work. All these components are connected to various parts of your car and their primary function is to create signals to counterfeit the attempt of the prospective thief to gain access to your vehicle.

One of the most common types of car alarms is installed in the door of the vehicle. These alarms make the switch send signals to the control unit each time the door is shut, and counterfeits any unwanted stab to gain access to the vehicle by making a deafening noise.

My car was almost stolen, but it’s a good thing I have installed this door alarm which called out the attention of the passersby as well as the authorities.

    David last December I purchased a 2018 Toyota Tundra pickup pretty plain Jane no trills. My last truck got stolen it had no alarms. I’ve done some research on some car alarms but they all say there are the best in the market. So much out there who can you trust to protect your truck or at least try. What are your thoughts on the Viper 5706V? I spoke with a “Certified installer” and he said not to get the one with the digital face because it would wear out sooner than you think if that makes any sense. This is what I would like to have in a car alarm:
    1. Noise (horn)
    2. Kill switch
    3. Activated by movement, like being jacked up to steal wheels
    4. lock/unlock doors
