How to avoid issues inside a Zoom Room equipped classroom

Audio - Only one audio source maybe present in a classroom, make sure you mute speakers and microphones on ALL other devices used in the room for Zoom.
Lecturer - The person speaking (lecturer) should be behind or near the lectern for best audio and video results as much as possible.
Camera - After walking into the audience, try to pass once behind the lectern so the camera can find you instead of having locked onto a student.
