Recently, I heard about some door jammers, so I want to know: what are they? What are they used for? Which doors can they block and how can they block them? The device you call a door jammer is not exactly a door jammer. The door itself has no blocking frequency, but if it can be opened remotely, it has a remote control and a radio frequency band to control the process. In order to block the remote control for doors (usually garage doors), there is a special interference device-remote control jammer. If the frequency with which they are stuck matches the frequency of the opening and closing process of the control door, it will be blocked. If there is no other way to open or close the door, it can be said that the door is stuck. Our door jammer can not only be used for garage doors, but if the frequency of its remote control is within the jammer’s frequency band, it can interfere with other types of doors. In addition, they have many other practical equipment.
We have provided an appropriate solution to your problem, and we are very good at blocking GPS-based trackers. Spireon VP2500 is a fairly simple automatic tracker that can obtain its coordinates from GPS and then simply send it to the server using CDMA or GPRS technology. The upgrade called Vehicle Path is a simple user interface. And the device is small and can be installed transparently. This is the main reason why many employers use such devices to monitor their employees. Basically, it uses GPS frequencies (L1: 1575.42; L2: 1227.60; L5: 1176.45 MHz) for navigation, and a simple gps jammer device will be able to prevent its ability to track you. But such equipment may not be very helpful in some cases. You should know that Spireon VP2500 can be upgraded to a variety of sensors, such as accelerometer, fuel sensor, etc. In this case, if you will use a simple GPS signal blocker-data from those sensors will still be transmitted to the server.
