The extremely negative situation, which has developed in the open spaces of the CIS with theft of vehicles, is aggravated every year. Experts explain this state of affairs as a whole set of factors: the lack of liability of state bodies in the field of control over car traffic, the carelessness of transport owners, and a low level of quality of security systems. This article will consider the features of anti -theft systems.
Several types of this equipment are distinguished: auto -signaling; immobilizers; electromechanical anti -theft devices; Security-search systems. Each of the listed types of equipment has its own functions, however, each of these devices cannot separately ensure the proper protection of the vehicle. Therefore, in order to build a reliable and effective security complex, one should consider the creation of several autonomous security borders. Of course, it is impossible to give a 100%guarantee of security, but this does not mean at all that it should be installed if only that.
The first security line – car system. One of the common names of this equipment is an anti -theft device. However, unfortunately, from the entire functionality characteristic of it (signal, security, service and anti -angle), the anti -theft qualities of the least impressive. Of a huge set of devices of this type, only a very small amount can withstand hijackers. A weak place here is coding algorithms that, being radio frequency, are available to everyone. When theft, “Code-grabers” are used, which are special devices that “produce” electronic master. A device that does not have protection against the Code-grabberry is the money that is simply thrown out.
The second security line is immobilizer. The main function of the immobilizer is to prevent unauthorized engine launches. These devices can be contact and contactless. The contact type of device has excellent crypto protection, but not too convenient in use, unlike a contactless type. In devices of a contactless type, a real chance is given to hijackers, through which hijackers can “run” the code. As for the recommendations, the best choice will be devices with a dialogue encoding algorithm. In the case of a limited budget, preference to the anti -theft device should be given to the immobilizer.
The third security line is a block. The security complex from car signaled and immobilizer is not reliable enough. For greater confidence, the presence of a lock is necessary. When choosing it, you should give special attention to the hood type devices: without eliminating access to the motor boxing, all other defense lines are ineffective. Choosing between a mechanical and an electromechanical lock, preference should be given only to electromechanical.
The fourth security line-security-search systems. The security-search systems include equipment that provides the opportunity to determine the location of the vehicle and block the motor.
The market offers many devices of this category. In addition to sufficiently high costs for installation, there is a payment of subscription expenses and payment of mobile traffic. The decision to use the security system requires balanced calculations. In the case of a high value of the vehicle, the use of security systems is justified. You should choose a system that combines two options for determining the location of the car, for example, GPS and security gSM car sign.
Security devices playing a secondary role.
For professional protection of the car, a number of devices (pagers, mechanical locks, GSM alarm alarm on the phone, devices based on original access algorithms) have a secondary role.
