The camera can track any number of targets (well, there's probably a limit, but I doubt that'd be realistic), but it all depends on the software that uses the camera. Sure, the camera may appear to track one target, but most likely it is choosing one specific target particle due to its qualities.

If you're going to play with vision, go play in Vision Assistant. You can then export from there a LabView VI, which you can use on the robot.
