Sambo is self-defense without weapons. The task of the car, which attracted the hijacker, is to hold out in this battle for as long as possible. But they teach this art in different ways. Some rely on comprehensive protection of the car with products of different brands, others rely on security systems, others believe that nothing has been invented better than non-standard electronic protection. Which is preferable? Having left a saving phrase like “Everyone chooses for himself!”, We will briefly talk about the features of each of the schools. Some basic solutions offered by each master are shown in our figure.
Here the philosophy is this: providing complete comprehensive protection of the car from theft. The approximate cost of the work is from 7 to 14% of the price of the car. Accept, as a rule, only new foreign cars. If you are interested, sign up, come, evaluate the scale of the forthcoming work and after that make a decision whether you need such protection or not.
What is interesting about her? The main thing is that the masters predict the scenarios of a possible attempt on a car and erect a sort of multi-level “mine” field around it: at least something will work. Well, electronic alarms, immobilizers, tags, DVRs, sirens - this, in general, is understandable. But in addition, access to the cabin is blocked by additional door locks with solid crossbars. The thief broke the glass, but this will not help open the door and get to the important wiring. In addition, the glasses offer protection by shockproof film - do not knock out from the first blow. Additional locks block and access under the hood. I liked the fact that here they are fighting against thieves, advanced in terms of electronic hacks: the car’s full-time controller is mechanically protected from replacement, and the diagnostic connector, which many cars almost instantly surrender without a fight, is replaced by another, completely different design.
Diagnostic Connector Adapter The standard connector of the master is replaced with a non-standard one, depriving the hijacker of the ability to connect to it. And for service visits, you just need an adapter with a standard output jack.
The protection of the standard controller is bolted with stall heads. The hijacker will not be able to replace the controller with his own.
Bonnet protection is not only an electromechanical lock, but also such sharp teeth. Their edges will prevent the hijacker from opening the hood with a pneumatic jack.
Electromechanical door lock. A regular larva can always be minimized, but there will be no sense in this.
THE ART OF ONE PUNCH
If other schools profess comprehensive protection, then the masters of this believe that one worked out blow is enough for self-defense. This technique can be considered a competent electronic blocking of a vital chain (or chains), performed individually, not like others. The logic is simple: far from every specialist will be able to calculate and bypass such a lock, and should not protect the anti-theft from various robberies and various kinds of tow trucks. As for the price, it starts at about 12, 000 rubles for a car like Kalina. To protect the Maybach will cost more - forty to fifty thousand …
Each alarm unit installed to the client is opened and individually modified here. For obvious reasons, I will not disclose know-how. It’s enough to know that if a cunning serviceman decides to slowly get to this unit during a scheduled maintenance in order to replace it and the customer’s keychain with shell ones, then there will be no sense.
As for the lock, we note the main thing: instead of the relay, only miniature electronic keys are used here. You can’t calculate them by sound and size, and hiding inside a thick tourniquet is not a problem for them. Which chains to block is decided individually: from crankshaft and camshaft position sensors to automatic gearbox solenoids. It is curious that for some reason the customers are afraid of the last solution: they say, do whatever you want with the engine, but it’s better not to touch the box.
Electronic guards quietly hide in harnesses, blocking vital circuits. Unlike electromechanical relays, they do not give out their presence and are much more reliable.
The main unit with an individual revision of the master. In particular, electromechanical relays are removed as an element of dubious reliability.
IN ONE BOTTLE
You can find a complex fully prepared for installation from one manufacturer. A system designer, unlike an installer, implements his worldview in a finished electronic product, trying already at this level to take into account both possible installer errors and the growing talents of hijackers. Such systems are usually suitable for installation on any car, and their cost, taking into account the work, ranges from 30, 000 to 50, 000 rubles.
At the first moment, the task seems obviously a failure: an uneducated installer will ruin all the ideas of the developer. However, there is nothing to turn to bad - there are authorized points! And a well-thought-out system of specially designed components of one brand is easier to install, and it will cost less than a “hodgepodge”. The main signaling unit with dialogue authorization and a CAN interface, an immobilizer (also with dialogue authorization), a GPS / GSM search and security device, miniature search beacons (battery life - up to two years!), Control of an additional engine compartment lock, free vehicle monitoring services - all this is usually part of the system, the cost of which falls within the indicated limits.
The frequency range of the 2.4 GHz tag. The control code is interactive. It blocks the engine after the start of movement. Can control the hood lock.
An autonomous search beacon will help you find a car through satellites or cell repeaters. A link to the map with the coordinates of the stolen car is sent to a mobile phone. Compactness and full autonomy make the lighthouse almost invulnerable.
The messenger is designed to notify the owner of the operation of security functions, as well as control individual vehicle systems from a mobile phone. You can control the alarm system by making calls to a number and entering a specific command, or via SMS.
