I am considering getting a desktop document reader/scanner for my linux desktop. I am hoping to do all of the following with the camera. 1) scan documents or book pages for OCR. From what I can determine 8MP is desirable for this. 2) view close ups large enough to inspect the solder (or at least the presence of) on fine pitch devices. (Electronics) 3) Use it as a web cam. I suspect my desktop is powerful enough to read the camera at the 30FPS, does webcam software in linux reduce the image enough quality for skype to work with a SLOW broadband connection? I am asking for opinions/suggestions. Here are the links to the two I am considering. https://www.amazon.com/IPEVO-Definition-Document-Camera-5-880-4-01-00/dp/B079DLTG9F/ref=sr_1_3?ie=UTF8&qid=1546648461&sr=8-3&keywords=document+camera And its more expensive cousin, even if it is too expensive for my budget. I HATE buying things twice. https://www.amazon.com/Ipevo-5-883-4-01-00-VZ-R-Document-Camera/dp/B0784RZNKT/ref=sr_1_6?ie=UTF8&qid=1546648461&sr=8-6&keywords=document+camera
