The camera needs 3 reference points. When you tilt the Pro clip, or move your head, that far, the camera cannot see all 3 points. The camera has 2 LED Status indicators on left and right side.
The left side LED gives you visual confirmation that the camera can see all 3 reference points. This will display with no program running. Just move the Clip, or Pro Clip( while powered on ), into view and the LED lights up green; if all three points are visible to the camera. If you move one of the points out of view, the LED turns off.
The right side LED gives you visual confirmation that the software has detected a compatible program running, and has loaded a profile.
Both LED lights will turn red if you pause the camera tracking.
In the software( camera view ), if the camera sees the Pro Clip, but the light level in your room is too great, they will turn red, and the status indicator will turn off.
You can adjust the camera sensitivity, LED intensity and IR brightness, on the camera tab of the software. Have you recently moved your computer, changed window hangings, change your light bulbs with something stronger or something to that effect?
Hope that helps!
