GPS jammer shields a variety of signals

Many car loan companies and car rental companies install GPS locators on their cars to monitor the rented vehicles to prevent renters from defrauding rentals and loans. However, such good things are targeted by criminals, as long as they are purchased on the market. A GPS signal jammer is installed on the car, the locator has no signal, the car is offline on the platform, and the car is stolen in this way. Is this true? Is there an anti-shielding GPS locator? It has to be said that this is the fact that GPS signals are the same as mobile phone signals and are easily interfered by electronic devices. GPS Jammers can shield all signals within a certain range, causing all communication devices in the range to lose their signals. However, this kind of equipment also has disadvantages for the users. The GPS signal jammer can only be turned on temporarily, and it is impossible to open it forever. As long as he turns off the GPS signal jammer, the GPS locator will have a signal again. , The car loan company will soon be able to find the stolen vehicle based on the location information.

In addition to GPS signal jammers, some people may say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also true, but this is only useful for some GPS devices. If the GPS locator is in a dormant state most of the time, the signal detector will not be able to detect it! why? For example, some GPS locators with wireless installation-free and ultra-long standby only upload information for one day a day, or even upload one information a week, or upload one information a month. After uploading, the positioning information is returned to the monitoring platform, and then it enters the dormant state. , It has no signal in the dormant state. It is impossible for car thieves to detect it! In addition, it is wireless installation-free, there is no wiring on the surface of the device, and it can be placed anywhere on the car (be careful not to place it in a place where the signal is blocked). It is very concealed and safe, and for high-end vehicles, it can prevent N A wireless device, in case you need it from time to time.
