4GIOT is based on NB-IOT wireless communication network, using NB communication module, mobile Internet, big data, cloud computing, real-time monitoring of fire protection facilities and equipment and surrounding fire safety environment status. When fire protection equipment collects fire alarm information or equipment failure, it will push the alarm information to the user end in real time. Users can use 4GIOT to understand the operation of the equipment, remotely reset and mute it, and share fire alarm and fault information with multiple people, so as to achieve early detection, early alarm, and early processing, and improve the fire safety supervision and management capabilities in many aspects.
