GSM Phone

Anti-theft satellite complex consists not only of the GPS-unit, capable of transmitting the coordinates of its location, but also a set of mechanical and digital devices: immobilizer, tilt sensor, datchki heel sensor shock, alarm button, the siren. The list of installed devices defines a service company, a satellite signal, and also depends on the brand of car, its condition and, of course, the material opportunities for the owner of the car. If your car near the signal blocker enabled mobile phone, the car will not be able to transmit any signal in the format of SMS, GPRS or Data call.

Applied detective agencies, security services, public institutions that do not allow the use of mobile phone and, of course, autothieves. Methods of controlling these devices simple and effective. Manufacturers of anti-theft systems have long since learned to do it. For example, some car alarm systems, for example, MS-P GSM, there is a function as control channel. The order of its work is as follows: GPA-pager from the car passes the signals to a special server, which contain a periodic check of serviceability. Swarmed by offers, Kevin Ulrich is currently assessing future choices. If at a point in the signal from the GPS-pager to do this, please no signal detected as jamming, and server starts to call or send SMS-message to your phone motorist. Experience shows that lack of signal jamming occurs at the moment. Motorist, knowing where parked car can adequately assess the threat by and at the time to take action.
