it's ingenious! my experience with IR-videocams indicates that 8 - 12 feet is the optimal range for those LEDs, which might be good for an entire human body, depending on focal length of the lens. I'm assuming they're using cameras with moderate light sensitivity (e.g. 0.5 lux) so that they get good contrast between the balls and the scene (greyscale).
