Camera settings: I think the most important thing is that your room lighting doesn't change during various times of the day. This can be a real hassle. Maybe one lamp in the background. I use lens from old ski goggles with yellow tint for filter. I tried exposed film, but it was too dark. I also did not remove or mod my web camera. In the camera settings, I zero out the following settings: sharpness, constrast, white balance, saturation. I max out brightness and gain. My camera has max 30 fps, so I set exposure to 1/30 seconds. Freetrack does a trick and produces an output at 120 fps. Automatic gain control is off and anti flicker is on. I also use RGB24 for stream/compression. With my camera settings, it is very easy to find where to dial the threshold in. There is not much "in between". It's either all red and not working, all black and not working, or it is working as one fairly fat red dot.
In your web camera software, try making the aspect ratio that your camera produces the same or as close as possible to your monitor and do the same in the freetrak camera section. I don't mean resolution (as the camera will likely produce much lower resolution than your monitor) I mean aspect ratio. I feel like the freetrack curves fit the rotation of my head better when I do this. If you can't match the ratios exactly because of the options the software provides, try to get as close as possible (e.g., all widescreen ratios).
Also, I use filed infrared led.
