Concepts and technologies are disclosed herein for a system that allows first responders to access information relevant to the first responder, such as localized presence and identification information. According to one aspect, data is collected from a plurality of internet of things devices in a building. The data is converted into information relevant to a first responder. A trigger signal causes a processor to access a data store to retrieve a floorplan of the building and the information relevant to the first responder. The information relevant to the first responder is mapped to the floorplan and displayed in a display device.
