What Are Main Types of Anti-Theft Devices for Cars?

Modern thieves use more tricks, so protection now works on several levels. Let’s take a look at whether anti theft device for car passive or active, works for you:

Passive anti-theft devices

Passive means they work without your action each time you park.

• Alarm systems - Turn on automatically when you switch off the ignition or close the doors. Most of the newer vehicles have audible alarms and other features such as ignition-key chips that shut off the engine when an incorrect key is used.

• Smart keys - Have the capability of keyless entry and ignition, can communicate directly with the computer of your car, and only authorized users can unlock it. They are available in most modern cars and can be retrofitted in older cars.

• Dash cams and car security cameras - These devices can ensure 24/7 surveillance and record motion or impact even when the vehicle is parked. Very useful in keeping off burglars and getting valuable clues in case there is an incident.

• Vehicle-tilt sensors & glass-break sensors - Sense tow-aways, or broken windows, and sound your alarm instantly. Adds easily to any existing security systems to provide extra security.

Active anti-theft devices

Active tools need a small step from the driver before leaving.

• Steering wheel locks - This is a basic and visual deterrent design that does not allow the wheel to rotate, even when an intruder succeeds in breaking into the engine. Easy to put on and take off.

• Kill switches - Secret switches that break the power to critical parts, such that the engine will not start even with the key. Most efficient since thieves are not often in a position to locate them within a short time.

• Tire clamps - Clamp on the tire to ensure that it does not turn. The vivid colors in themselves usually frighten thieves, and the car cannot be moved at all.

• Brake locks - This type of lock is attached to the brake pedal to prevent pushing it down. Even when one switches on the engine, he or she is not able to drive away.

• Faraday bags - Disable block radio signals to prevent keyless entry fob attacks. An excellent anti-theft system for cars.

• Remote locks - Have the ability to lock and unlock your automobile remotely. This will keep your car secure and difficult to access by anyone without permission.

• Battery-powered magnetic tracker: This battery-powered tracker sticks under the frame and runs for weeks on one charge.

• OBD-II plug-in tracker: These trackers plug into the diagnostic port and show live engine status.
