14.1.23. Protect the car


It is possible to complain as much as necessary about the authorities which are not accepting due measures to reduction of number of stolen cars, the laws insufficiently severely punishing modern horse thieves, and in general all and all. But, as they say, "god helps only to those who does not forget to help to itself(himself)". The one who worked to equip the iron horse with a reasonable set anticreeping devices, as a rule, it does not lose.

To hijack the car, it is necessary to get inside. For this purpose there are only two ways: to break glass or to open the lock by means of a key, a master key or other adaptation. It is possible to go deep, of course, into technology of this business that in itself nebezinteresno. But from us it is enough of that criminals it perfectly know. And what it can oppose?

It is possible, certainly. to go by a collector armored car – there glass you will not break even by means of "Kalashnikov". You agree? It is possible to go on simpler way – to increase durability of glass. For example, by means of special "reserving" films. With keys it is more difficult. It is possible to put the additional lock, but as practice shows, it is not too effective protection. However, if there is no possibility to prevent car opening, it is necessary to learn at least about it is any alarm system works when opening door.

The following step which the car thief should make, – to start the engine. Exactly the main boundary of defense of the majority of anti-theft devices available in the market here lies. And for immobilizers is a main task, and for alarm systems – auxiliary. Certainly, all blocking are surmountable. But remembering that absolute protection does not happen, we will try to create to the malefactor probably more difficulties. And in this regard competently put immobilizer the predpochitelny. Besides, for removal of blocking it is necessary to open a cowl. Therefore will not prevent to put on it the additional lock.

Pay attention: both the immobilizer, and alarm systems differ on level of protection and number of the main and additional functions. Thus the price depends both on the first, and from the second circumstance. And high cost of system – at all a sign of high security properties. Possibly, simply in it there are a lot of support functions.

The started engine and the car going in the necessary direction – not same. The last boundary of protection of the car is based on this postulate. It is made by every possible mechanical systems – the lock of a wheel, pedals, the transmission lock... If there are bases to be afraid that the car will be simply dragged off on a tow, it is possible to apply a blocker.

Now we will pass to practice. Having looked at advertizing, it is easy to be convinced that anti-theft devices are very various. It is necessary to estimate features of use of your car: what it brands, what its technical condition, where as well as with whom you usually go where leave the car regularly where occasionally where she spends the night etc. Depending on it it is necessary to estimate risk of stealing. After that you will precisely know, those victims which it is possible to bring for the sake of safety of the car how are great. Such knowledge very much is useful to you at negotiations with a fitter.

Certainly, the competent manager in firm fitter of protivougolnny systems should find out that it is required to you. Besides, nobody knows better it all features of available systems and devices and anybody better it cannot help to pick up to you "for a place" the necessary configuration and a complex of protective equipment. Therefore treat with great attention to everything that he tells you, and adhere to common sense. Do not forget that the manager has also interests.

At times inexperienced people тычут a finger in the most expensive systems, believing their best. Then come with a request to disconnect function, then another... Eventually they have a question: for what плачены money? Do not overestimate the possibilities. If face anticreeping systems for the first time, choose the simplest in management. What is "the enraged signalka" know? Is not present? Means, you were lucky with neighbors. More often the alarm system "goes mad" because of the wrong treatment of her and inability to understand an abundance of the main and additional functions. And business at all in stupidity of certain car owners. After all if the car rebels because of operation of anticreeping system, it is very difficult to inexperienced person to think that to what. And therefore do not forget to take from a fitter the instruction of the user and are not lazy with it in hands a little to practise. In desert, certainly, a place.

However, alarm systems rage not only because of maloperation. And therefore the question of reliability is quite actual. Reliability more depends on a fitter. Here it is necessary to rely on its reputation and guarantee certificates. But serviceability of the car is not less important. So if want to protect a second-hand car, in advance prepare for additional expenses on repair of locks, electric equipments...

Let's call the five most, in our opinion, "reliable alarm systems": Bosch, Clifford, Sirio 777 Mouse, Sicura, Prestige.

Absolute protection is impossible. After all as a last resort always it is possible to ship the automobile car in a body of the truck or to drag off it the wrecker. But today stealings of cars is a business, and any business aspires to reduction of costs. Therefore the preference is given to the cars which are not complicating life. So create to car thieves of difficulty.


In Soviet period "sekretka" – hidden in a jungle of podkapotny space or salon back streets the additional switch of ignition was one of the most popular anticreeping means. During Post-Soviet times it became clear that this device is not alien also to the capital world. However, there over it properly worked, therefore the device, called "immobilizer" turned out.

The main task of an immobilizer – to break off one or the several vital for operation of the car of electric chains and thus to prevent stealing. When using additional devices, for example electromagnetic valves, blocking of work of not electric systems is possible also. The main feature of an immobilizer is that at its destruction or unauthorized shutdown of system of the car remain blocked.

Anticreeping systems

Aspiration as it is possible to protect more reliably the car from stealing conducted to development more and more difficult designs. So there were devices which it is more correct to call anticreeping systems. One of them – "Vekta". In it the main unit is executed not folding, all wires have one color, and some of them – false. "Vekta" allows to break off four chains, and in two to change polarity of wires.

The "cyborg" who is actively advanced on our Alarm-Servisom market, – system of higher level. In it the main unit is connected to regular conducting of the car, and ruptures of the vital chains are carried out by special devices. The small sizes strongly complicate their search. Besides, "Cyborg" has the wide list of additional functions and is connected to a city paging network. It is possible to call by the car to phone and to order to be got. Or, on the contrary, to stop.

Alarm systems

Initially the idea consisted in informing the owner on attempt at his favourite.

Modern alarm systems far left from primitive systems on "two buttons". Practically all of them have remote, from a brelka, inclusion – by means of infra-red beams or radio-waves. In the latter case the code is applied double or floating, constantly changing. The block architecture is widely applied: the main unit can work with a wide set of sensors, the exit can be connected to a regular signal of the car or a siren – usual or with the independent food, reacting to electricity shutdown. It is possible to manage and without noise if instead of a siren to connect a pager (do not confuse to a paging network, is other pager) which will begin to squeak in a pocket of the owner of the car at alarm system operation.

Modern alarm systems and anticreeping functions are not deprived. Even simplest of them blocks work at least one electric chain. Basic difference from immobilizers consists that at shutdown of a food of blocking are, as a rule, disconnected.

Modern people love every possible services. Well, unless it is bad, if the alarm system itself closes locks of doors? Today it is possible to consider this function standard.

Additional locks

About ten years ago in a remote place it was possible to see not only the truck, but also quite respectable "Volga" with huge eyes sticking out of a door under the hinged ambarny lock.

Then the first in our market the devices blocking a steering wheel and pedals "went". Motorists with an experience well remember these massive железяки a horrible look.

It is necessary to mention and "the Israeli miracle" – Mul-t-lok – the lock fixing the lever of gear shifting. It is obvious that with "machine gun" these devices protect the car better as the mechanical box allows to tow the car with the squeezed-out coupling.

The following type of the anti-theft device – a blokirator of wheels, a thunder-storm of breakers of rules of a parking.

And at last the last design - the additional lock of a cowl. However, the in itself lock does not represent a barrier to the car thief. After all for start of the engine of the modern car it is not required to open a cowl, and furthermore – a luggage carrier. Therefore such locks are good only as the additional measure complicating access to the alarm system or an immobilizer.

Jackie against gop-stop

From all variety of functions one deserves the separate story. It is protection of the car at assault. Are most widespread "Jackie" – Hight Jack and Black Jack.

Huy Jack joins with a brelka – that puts the car on protection, or own. In principle the following is provided: here the car at you selected, and you "threw out". You fast press on the button. There is a following further: at once or with a small delay глохнет the engine also turns on the alarm system. After that to bring the car into a working condition by means of brelok it is already impossible. Certainly, to include Huy Jack it is necessary before the car will leave out of action limits a brelka. The shortcoming consists that "throw out", as a rule, from the car with keys and a brelok, and therefore it is necessary to have all the time with itself an additional charm or at least to store the main separately that, you see, it is not so convenient.

Blek Jack it is not necessary to include. It needs to be switched off. Usually after each opening of a door. Otherwise he warns the forgetful driver, and then stops the engine, but during the moment when the car thief will dump "gas" that does a stop of the car of safer as for the owner of the car (robbers already far), and for those who goes nearby.
