The blocking is more passive, the better
From stealing of immunity is not present. If the car can combine the price, it potentially is the goods, so – and object of stealing. That can be stolen, will be stolen. A question only where and when.
The most perfect protection frame there are electronic systems – the security alarm system and antijoy ride devices. The problem of the first – to notify on attempt of stealing and to have on the thief psychological influence. But what from it to sense if the car costs in the street, and the bedroom windows leaves in a court yard?! Even in time worked, it does not cause anything in passers-by, except irritation. The thief too it is not strong "хвылюется", knowing well that has worked only пугач. For now the owner will put on sports trousers and will go down on the lift, it is possible to have time to reach and the Canadian border. Therefore the alarm systems of the American type so popular in the CIS, in Europe are not applied. After all at false operation the owner should pay all departures on a police squad scene. Fortunately (in this sense), our militia on howl car sirens reacts extremely seldom. On its call runs the owner compelled at first to be convinced only that the alarm not false and only then to cause militia. And in expectation of they be to try to beat off the car. Противоугонки is much more effective, more difficult and more expensive simultaneously.
Abroad the best advertising of security system is the recognition its association of the insurance companies. Otherwise to be put on the market with it it is not necessary. Also that is not has gone at "them", has now captivated our market. At us the similar association is not present, therefore the insurance companies are compelled to spend examination independently.
Let's generalise some from put forward requirements – we will allocate the basic components of systems on degree of protection and we will estimate their efficiency.
I. Admission Systems in salon and engine start
Betray the owner if have got into strange hands. The locks which have appeared recently of system Tlris – not an exception. We will remind, there in a key the coded microcircuit without the power supply, in the lock, accordingly, the reader (radio input reader) periodically requesting a key is built in. If the microchip is identified, the system disconnects the alarm system and will unblock the engine. Alas, Tlris protects only from master keys and counterfeit keys.
Radio- or ultrasonic communication are used infra-red. It is convenient, but can betray as. And if the battery creates one problems has sat down: neither to put the car on protection, nor to remove from it, to unblock the engine. And, at the most inappropriate moment. And many already happened car thieves of own car.
The system refuses, if the director of hindrances – the broadband generator of noise or to it the similar device is nearby included. And opening means – сканнеров, грабберов, etc. Already ненамного, than systems.
Card or charm Tlris
Thing even more convenient. While is in an operative range of the reader, automatically confirms the right to start of the engine and driving. If communication is lost (the driver with a card has left the car), the engine is automatically muffled. Does not distract the user and provides the highest comfort. But, as well as other material carriers of the password, unapproved access supposes, having got to the thief.
Attempt to receive a comfort maximum, having applied some carriers Tlris, leads frequently to result opposite – to their conflict at the next reading and protection operation.
The type-setting password
In secret services this kind of the admission is considered the most protected. There are two inconveniences – it is necessary to remember the password and to enter it. But cars with similar systems of the admission keep up much less often. And to enter the password it is not more difficult, than to dial a phone number. For this reason many already start to combine system from the inexpensive alarm system and противоугонки with a set of the password for the admission. And firms-manufacturers had time to adjust their release operatively. In modern prestigious cars this mode include in the program regular onboard кмоптютера.
The systems, demanding to enter the password after engine start.
Otherwise the engine will be muffled at the first braking or decrease in turns. In it their main lack also is covered – do not reduce speed and steal. The second minus – the simplified password as it needs to be entered into movement time.
The combined systems of the admission
For example, a radio charm or card Tlris for external protection and the admission under the password for engine start. The steadiest system on protection degree.
II. The Alarm system (sound, light and a radio pager)
It is applied two levels of the alarm system – warning and disturbing. Disturbing should join, if have not reacted to the warning. Joining without cause, it only irritates and soon the attention ceases to draw. It thieves often use, specially disturbing the chosen car. Sometimes use monotony of voices of sirens – near to the chosen car put the with the same siren and periodically include. When the owner has ceased to react, from "training" pass to actions. Therefore take care, that sounding of your alarm system differed from others. Or buy a radio pager.
He without superfluous noise will operatively inform you that occurs to the car. Some connect the relay including a lantern of illumination a parking lot to a pager and such reception simulate vigilant supervision. But consider that the pager as easily chokes with the director of hindrances and always there is a chance in the morning to rise is sweet slept, but a little grown poor.
III. Systems of blocking of start of the engine or its compulsory deenergizing
The foreign insurance companies demand, that the antijoy ride device provided blocking not less than three knots: a starter, ignition and топливоподачи. And as consequence – passive blocking of the engine if the processor does not work it (is disconnected or destroyed).
The active provides иммобилизацию only at the working processor. Besides to leave possibility to use the car at refusal of security system, in many of them the mode of normally closed contacts of blocking relays is applied. It car thieves also use: to tear off a wire of a food of the main block enough – and all system is neutralised. To find it even among identical on a thickness and colour a wire, the bulb with sharp щупом will suffice. Wire isolation is pierced, is remained energised at the switched off ignition and a direction of the further actions clearly even двоечнику.
If wires from blocked chains converge to one block, the car thief it only facilitates a problem. The decision occupies pair of minutes. Here again advantage behind passive blocking, especially if is microimmobilizers and they are scattered on all car. And the more so, if they are built in in regular blocks of the car as thus to neutralise their crosspiece it is simply impossible.
In the systems providing compulsory muffling of the engine, the alarm system warning should work that to the car there is something wrong and it is necessary to steer clear of it. Otherwise there is a chance to return the car which has suffered not so much from the car thief, how many from involuntary neighbours in a line.
IV. Systems of return of the car
It is a question of suppression разбойного stealing. At it it is more reasonable to allow to drive off to the car thief and on a safe distance for you compulsorily to switch off the engine. The mode usually joins from a special charm. But its car thieves, most likely, will select, and at movement will try not to reduce engine turns. As similar systems too switch off the engine at decrease in turns below certain level. Or apply the director of hindrances then also necessity to take away a charm will disappear.
And it is even more probable – will roll you in the car, yet will not reveal all traps. Then will suggest to disconnect all of them, to train to do it and only after that will turn out. Here then chances of car return practically does not remain.
More precisely so was until recently. There were the systems, allowing a call by phone to block the engine on removal in tens kilometres. About one of them we have learnt recently, at reception of a pager of a network "the LINK a TV set". In the list of applied services appeared and "пейджингвая the security autoalarm system". The more deeply we penetrated into a system essence, the more it interested us. To avoid charges in advertising, we not begin to result its name, we will list only the elements which have seemed to us Ace of Base ("an as in a pack").
It is the specialised onboard computer on the basis of processor "Intel", trained to protect the car. The system is constructed on the microimmobilizers placed near or in object of the control. Them can be to eight independent. It is possible to include any reasonable quantity of signalling devices and sensor controls in it. Management of system and input of passwords of the admission are made manually from the two-push-button keyboard. Indication of conditions, acknowledgement of performance of operations and some helps are made by the multi-colour indicator and musical signals. Probably operative reprogramming for changes of algorithm of work of system. Компьтер it is protected from influence by an electroshock or from statement of a radio noise and remembers attempts of their application. Installation of the receiver of paging signals ("Motorola") for reception of external commands is possible. Elementary of them – a sound pager: the processor on a radio command loses in salon one of a set легкоузнаваемых melodies. So it is possible to transfer to the driver conditional messages, without distracting from driving. The system price in the minimum configuration – about two hundred US dollars, with the receiver – is twice more.
