Anti-theft protection - radio terminals installed on a car will help determine the exact location of a stolen vehicle, cargo or any other valuable asset. A small device does not disclose its location, and systematically, depending on the settings and the specified time interval, sends a signal to the server. In case of an emergency, or as a result of car break-in, the terminal activates the "alarm" mode and connects with the server according to the schedule specified for it. It is up to the user to set and program himself an acceptable length of time during which he will receive the corresponding message. The radio terminal will not only determine the location of the vehicle, but will also be able to block it to prevent further movement from a fixed location. Such car devices provide a certain peace of mind for the owner and provide a quick solution to the problem in case of emergency.
