1. A system for monitoring of hand hygiene compliance on a local network in a clinical room, the clinical room including a patient zone and a hand hygiene station outside the patient zone, the system comprising:
a first camera configured to capture first image data from a first viewpoint in the clinical room;
a first hardware processor configured to detect a person in an image frame from the first image data and assign a boundary box to the person, the first processor further configured to track movement of the boundary box in subsequent image frames from the first image data;
a second camera configured to capture second image data from a second viewpoint in the clinical room;
a second hardware processor configured to detect whether a hand hygiene activity has been performed from the second image data; and
a plurality of display devices in different locations of the clinical room, the first processor and/or the second processor in communication with the plurality of the display devices,
wherein the first and/or second processors are further configured to receive configuration information of the clinical room from a server upon initiation of the system, wherein the configuration information comprises one or more of display device locations, camera locations, an entrance location, a hand hygiene station location, and/or a patient bed location, and
wherein the first and second processors are in communication with each other, the first or second processor further configured to:
determine that the person to whom the boundary box is assigned has not performed the hand hygiene activity,
locate, based at least in part on the configuration information, a nearest display device of the plurality of display devices to the person, wherein the person is entering the patient zone, and
output an alert to the nearest display device.
