First off, motion tracking with video is limited, don't expect
amazing results, because no one in the world is getting them. If you
are serious about motion tracking, then you need to have a high-
quality camera, not a webcam, they are too noisy. Also, you'll have
much better results if you use a black&white camera with an infrared
filter. Color cameras generally filter out infrared, so they won't
work.
These projects use this kind of camera setup:

Usually you need to lock the iris/exposure of the camera, otherwise the thresholds you set for movement in software become largely useless. You may be able to set those things to a manual mode in the device settings... Obviously you also need to have full control of the lights so that it does not change...
Other than that HCS is right here, don't expect much.
