When purchasing and using vehicle mortgages, it is best to configure GPS jammer within a certain stage. Especially some car dealers who hand over the car and purchase the mortgaged car, in other words, once they receive the car, they can turn on the GPS jammer and put one in the car, and one in the car trunk! When the shield is turned on, you can be assured of peace of mind when you take the car back and forth. However, the jammer cannot be activated 24 hours a day, so after the safety reaches its own chassis, you must find a technical professional to investigate the GPS by yourself, and modify the GPS positioning equipment and mortise locks, key changes and other security guards to prevent mistakes. just in case.
1. Understand the GPS jammer
GPS jammers (jammers) can reasonably prevent being tracked by GPS communication satellites, reasonably affect GPS communication satellite signals, and maintain your track privacy protection and information business secrets.
2. The function of GPS jammer
The GPS signal is the same as the signal on the mobile phone, it is very susceptible to the influence of electronic components. The signal jammer can shield all the signals in a certain range, so that all communication devices in the range lose the signal. The installation of a GPS locator on the car enables buyers to easily find their own car on the GPS monitoring management platform. As everyone knows, such a good product is also found by criminals to find loopholes. If you buy a signal blocker on Taobao, Turn on when the car is stolen, there will be no signal in the car, and the car will go offline on the service platform, as if the whereabouts of the car are unknown, you can’t find it anyway.
3. Disadvantages of GPS locator
I have to admit that the GPS jammer also has disadvantages for the user. The signal jammer is only temporarily turned on, and it is unlikely to be turned on all the time. If he turns off the jammer, the GPS locator will have a signal again. Drivers can quickly find the stolen car based on precise positioning information.
In addition to signal jammer, some people will say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also an objective fact, but this is only valid for some GPS devices. If the GPS tracker is in a dormant state most of the time, the signal detector will not be able to detect it! what happened?
For example, some ultra-long standby GPS locators can only be awakened once a day. After being awakened, the precise positioning information of the vehicle is sent back to the buyer’s network platform and then it enters the dormant state. In the dormant state, it is Without a signal, it is absolutely impossible for car thieves to detect it! In addition, it is also free of wireless network installation. There is no wiring on the surface of the machine and equipment. It can be placed anywhere on the car (if it does not have to be placed in an area blocked by the signal). It is very concealed for engineering safety.
