The '2016 R2' SDK has Person Tracking functionality too, though its functionality is limited and it is hard to get working. Officially it supports both the R200 and SR300 camera models, though in practice the R200 is the better choice of the two for person tracking, because it has a long depth-sensing range of up to 4 meters and excels at human body scanning, whereas the SR300 is better at scanning smaller objects and only has a depth range of around 2 meters (so it can be hard to fit the entire body into the camera's view at close range).
