Additional meeting and call-related features and issues within Microsoft Teams for business
Hello !
We deployed some of these in my business with no issues. There is no "recommended" length away from the camera : it depends on your wanted setup.
What is the dimensions of your room ? Do you want the camera to see the person at the blackboard ?
I suggest you to do multiple tries, and settling in the better-looking solution for you.
As a matter of fact, in our business, we choose the camera to be 2 meters away from the meeting board.
Feel free to ask any other question!
