Where attendees are close to the camera, will need a wide angle HFOV. For instance a camera with a wide angle of 90 degrees will capture anything within a field twice as wide as the distance from the camera.

This is only 41% of the wider camera image and would not capture people seated at the front of the table. See the graphic below for examples:
