Incident Management Application

Mercury Dris is a mobile application designed for security patrol units to manage incident reports in real-time. The app features secure login, status tracking, and live location updates to ensure efficient patrol management. Upon login, patrols can activate or deactivate their availability, receive push notifications for new incidents, and accept assignments based on proximity and availability. The app provides detailed incident information, including maps, images, and object details, allowing patrols to take action quickly. Patrols can only accept one active incident at a time, and once an incident is claimed, it is removed from other patrols' lists. The application enhances patrol coordination and efficiency in incident resolution through an intuitive UI and integration with the backend system.
