This could be an issue with the scanning environment, but is, most likely, due to the router used. If there isn’t a quality signal available, the Skanect Uplink will perform badly.
I would recommend, first, trying to eliminate any environment issues by using lights that project a low amount of IR light. I would, also, recommend covering any windows present in the room while making your scan.
Finally, I would, recommend seeing if your computer running Skanect is the issue, by checking the following page for Skanect’s minimum requirements: http://skanect.occipital.com/download/. We obviously recommend that you use a computer that is more powerful than the recommended requirements.
You can check if your computer is running fast enough by checking the frame rates present (fps) in Skanect while scanning. We recommend trying to keep your FPS at 20-30 FPS while scanning is taking place.
Let us know if this helps!
