Types of car alarms
The alarms on the market today are many and very different: we can group them into three broad categories: electronic, satellite and mechanical
Among the first there are those mermaid, with specific sensors on the inside or outside the vehicle starts playing when someone approaches the car. The sound should be a deterrent to thieves but not really hard to defuse it, so this type of theft is not a secure system to protect their cars and hardly reliable. Another type of electronic theft is c.d. immobilizer, which prevents the car to get going without the key to breaking the electrical circuit. Although it may seem more reliable than the previous device in question can easily defuse and therefore unsafe, to the point that many refuse to take out insurance policies for cars so equipped.
The other type of car alarms, most notably those of satellite positioning systems that use, such as a siren, sensors can detect are the danger. Using the GPS can also easily know where the car is as this information is transferred to the phone owner via SMS. At this point it is easy to retrieve their car. However in the absence of the satellite signal does not work and therefore is useless in areas where the signal is intermittent or no.
Do not forget that there are special appliances that can reverse the signal even 100 meters away. These are known as mobile jammers and “white noise generators” whose instructions are accessible to all on the Internet. With these devices becomes extremely easy for any thief to open the machine and put it in motion and once completed the theft and brought the car “safe”, the burglar can remove the noise and no one can find the car.
It is not difficult to obtain a similar unit. In fact I found many internets although they are legal. The only people allowed to use these devices are the forces for defense only in specific situations and places. The means to prevent operation of car alarms satellite do not end there. There are also covers of lead or CD, or call repeaters that are designed to keep busy the number recorded in the satellite system. As told by a remarkably high but the other scares us to ask how do insurance to protect themselves from everything. In some cases, contracts include a clause which states the need to ensure that the satellite alarm is working properly and it began operation in case of theft.
