How to take pictures of a blackboard or whiteboard and write on it

In this page, we introduce a method to take pictures of a blackboard or whiteboard with a PC camera and stream the pictures via Zoom for writing by hand in class.

Here is some information about this method that was shared with us by our faculty staff.
