Is it possible to get greyscale video out of the camera?
Yes, the FLEX:C120, V100, FLEX:V100R2 and V120:SLIM cameras have the capability of transmitting the entire greyscale frame to the PC. The OptiTrack SDK provides the ability to select this video mode and access the data. FLEX:V100R2 and V120:SLIM cameras also support compressing the entire grayscale frame with MJPEG* inside the camera. This significantly reduces the USB bandwidth required to transmit the image (usually 1/10th of non-compressed). * MJPEG mode support not available in the OptiTrack SDK. The FLEX:3 cameras only transmit 1 bit monochrome thresholded video; this means anything below the threshold is off and anything above it is on. The individual bright objects in the video frame get color coded based on their rank among the other tracked objects; the color is then superimposed over the video stream. The color information is not part of the actual video stream.
