A weapon monitoring and remote support system monitors firearms and other assets within a deployment location, and includes a graphical user interface providing a top-down geographic view of the deployment location and coverage areas of weapons within the deployment location, the coverage areas representing positions and orientations of the weapons determined based on sensor information received from one or more sensors of each of the weapons. The graphical user interface may automatically update according to received sensor information, where the updated graphical user interface represents a change to at least one of the coverage areas of weapons, and output instructions for displaying or rendering the graphical user interface to one or more computing devices.
