Types and effectiveness of anti-theft systems for automobiles

If you have an accident, a car not able to go and the evacuation cars in Moscow, St. Petersburg or any other city, you must first disable car alarm that virtually all motorists to set their favorite "iron horses". Some types of these devices are more complex and expensive, others are simple design and low price. Try to understand their types and degrees of effectiveness. All of the existing anti-theft systems for vehicles can be divided into three main types: car alarms, mechanical interlocks, immobilisers and satellite systems. The most common ones - car alarms. They serve the "voice", if your car someone disturbed with illegal intentions or if tow Odintsovo come to pick up the car alarm and alarm system you will not be disabled. And the report of the attack on your property, these four-wheeled alarm can not only sound signal, but also more high-tech means, such as by sending a message to a cell phone or pager. Unfortunately, this method of protection against unauthorized use can be effective only if the owner of a car nearby. If you think a little and remember the classics of Soviet cinema, the prototype of the modern mechanical protective device can be considered a trap, in which the "noble thief" Yuri Detochkin hit while trying to steal another "Volga" in the film "Beware of the Car." Now, however, are not so bloodthirsty: the gear box, steering column and cowl just installed mechanical interlock, which can be removed only with special key. In principle, they are more efficient than car alarms, but the hijackers are not born yesterday, and quite famously picked these devices lock picks. Sufficiently reliable means against theft immobilizers are. If you attempt unauthorized access to the car, they just block some electrical circuits and the car did not give him a start. Recently, there were "tricky" immobilizers, which play with the hijackers, a cat and mouse: first, allow to start the car, and then jammed the engine, simulating a fault. The most reliable and effective anti-satellite systems are. Their work is based on Global Positioning System GPS, which allows you to track all movement of the car and find her anywhere in the world. If the car is stolen, then the central control room receives the appropriate signal, and from that moment for them begin to follow a variety of serious and competent "comrades", including from the Interior Ministry.
