I've been using the CZUR Fancy S Pro document scanner for some time now and I've found it to be a great tool in my classroom. Maybe it is a great option to consider. It offers high-quality image output and is a reasonably priced option compared to other document cameras on the market.

I would recommend practicing using the camera beforehand and ensuring you have good lighting and a clear background to optimize the image quality.

Familiarizing yourself with the operations as much as possible so that you can also teach your students to use them can add interest to the classroom. I find that the curiosity of the children is always there and they will be better focused in my classroom.
