FireWatcher is the first fire-monitoring mobile application system designed to be used in tunnels in Hong Kong. It provides extraordinary convenience for users by redefining the fire monitoring mobile system. It provides various main features for users, such as receiving a detailed notification when a fire is detected and allowing users to see the tunnel floor-plan even if their mobile phones have no network or signal. The system can also graphically locate the fire on the master plan with red dots to indicate exactly where the fire has occurred.

FireWatcher (LoraWAN) is a new-generation of Fire Alarm Management System (FAMS), based on the new-generation of wireless Internet of Things (IoT) and LoraWAN-based sensors, to provide long-range, low-power implementation.
