I just bought ahere.
In any case, recording directly from this document camera is NOT straightforward, in part because of the lack of documentation, and also a bug in the current version of the VLC player.
Here are the instructions. They were quickly put together, mostly for my own purposes, so they are a bit terse. I may make a video of this at some point, in which case I will edit this message. Note: My VLC player is up-to-date (version 2.2.1) and I did all of this on a Windows 7 notebook computer.
