Auto Security Systems

If a person, more often a pro, wants to steal your car, they probably think they have the know-how. Of course you want to protect your vehicle from pros, but greater consideration should be given to devises which will help keep your car from being stolen by amateurs. You may have an electronic anti theft devise or even the club but still your auto can be taken. There is no fool proof auto security system but consider this – most cars are broken into below the door line and therefore out of sight. Many vehicles with build in antitheft alarms give no warning that the car is so equipped. It stands to reason that the best way to deter a thief is with a visible indicator.

It is my understanding that a visible indicator is effective in deterring fifty percent of potential thieves. If the perpetrator sees a flashing light, chances are that they will move on to another vehicle. They have no way of knowing if this light is a dummy or the real thing!

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.

Thatcham Car Alarm – Difference between Cat1 and Cat2 to 1

Thatcham car alarms are approved by UK motor insurance companies and by fitting a Thatcham approved security system you will enjoy cheaper car insurance and a high level of car security.

Thatcham car alarms for vehicles without a category2 immobiliser must be be fitted with a full cat1 alarm with integrated 2 or 3 circuit immobiliser all combined in one unit. These Thatcham car alarms tend to be fitted to older cars or unofficial imports where they are not designed to UK specification in terms of Thatcham security systems. Thatcham car alarm systems for cars with cat2 already installed are cheaper and quicker to install because they use the existing immobiliser so they are less complicated to manufacture and install. Cat 2:1 Thatcham car alarms are suitable for newer UK specification cars as most of them come factory fitted with a class 2 immobiliser

The Thatcham organisation is an independent body set up by the insurance industry to improve vehicle safety and security for cars, vans, HGVs, motor bikes, plant and other vehicles. Thatcham do not manufacture car alarms but they do set design standards for car alarm manufacturers to meet and each alarm is given an evaluation code if it passes and makes it onto the Thatcham list of car alarms. Some of the best know Thatcham car alarm manufacturers are; Avital, Clifford, Cobra, Gemini, GT, Toad and Viper. Specifications vary from each manufacturer and model range but they all have the following basics; door, bonnet and boot protection, ultrasonic or microwave interior protection, 2 or 3 circuit immobilisation, a self powered siren, remote control central locking, 2x high security remotes and battery backup siren.
