1. A method comprising: monitoring output from at least one sensor configured to sense, in a room of a building, activity associated with a patient falling; based on the monitoring of output from the at least one sensor, determining to capture one or more images of the room; based on the determination to capture one or more images of the room, capturing, with a camera positioned to include the patient within a field of view of the camera, an image of the room; analyzing the captured image of the room to detect a state of the patient at a time of capturing the image; determining, based on the detected state of the patient, a potential fall event for the patient; and based on the determination of the potential fall event for the patient, sending, by a communication device, a message indicating the potential fall event for the patient, wherein the at least one sensor configured to sense activity associated with the patient falling is an on-body sensor configured to detect an impact and determine a change in an orientation of the patient; wherein monitoring output from the at least one sensor comprises: receiving data indicating a detected change in an orientation of the patient and an amount of the orientation change, receiving data indicating a detected impact and a severity of the detected impact, determining, based on the received amount of orientation change and the received data indicating the severity of the impact of the patient, a threshold for inactivity of the patient, and determining, based on output from the on-body sensor, that the patient has been inactive for a period of time greater than the determined threshold; and wherein determining to capture one or more images of the room comprises determining to capture one or more images of the room based on the determination that the patient has been inactive for a period of time greater than the determined threshold.
