1. A method for tracking a status of a person in a clinical room, wherein more than one person is present at the clinical room, the method comprising:
receiving first image data captured by a first imager from a first viewpoint in the clinical room;
detecting and identifying the person in an image frame from the first image data;
assigning a unique boundary box to the person;
tracking movement of the unique boundary box in subsequent image frames from the first image data by assigning the person to a track nearest to the unique boundary box;
outputting the track to a server to store the track in a database located at server;
receiving second image data captured by a second imager from a second viewpoint in the clinical room, the second imager being oriented with a downward tilt and at a higher location than the first imager;
assigning the unique boundary box to the same person detected in an image frame from the second image data by comparing the first image data and the second image data;
detecting an activity of the same person based on the second image data;
updating a tracker status of the person based on the activity and/or location of the person.
