The app remotely controls the vehicle fortification alarm through the wireless network, accesses the data server through HTTPS to obtain the vehicle GPS positioning information, and displays it on the app map interface. When the vehicle has an abnormal alarm, it will send an alarm message to the app through the socket connection. When the app receives the alarm message, it will pop up the alarm message and play the alarm tone. The vehicle fortification and disarming can be remotely controlled through the app, Launch, vehicle search and other functions. After installing the app for the first time, users need to register and log in, or log in to the existing account, and then add the vehicle equipment number before they can remotely control the specified vehicle and obtain GPS location information
