I bought an Inswan document camera a while ago and have been using it to take pictures of all my paperwork for filing purpose. It worked pretty well. Recently, due to the Corona virus situation, my daughter was forced to do all her school projects at home. As a result, she had to look for a solution to effectively demonstrate how to perform certain tasks to her teammates in real-time over the internet. She was thrilled after realizing she could integrate my document camera with Zoom, Skype, or Google Hangouts to do just that. So she started using it and got even more thrilled when she discovered she could annotate her video footage in real-time and write comments directly over anything on that screen. This feature proved to be extremely useful during their web conference discussion. And since this camera works with both Mac and Windows PC, pretty soon everybody on her team bought the same camera. So as a result, collaborations among all team members became even more effective. In the end, her team got an A for the project. Brovo! I highly recommend this camera.
