The virtual room is an extension of the courtroom. The court has the right to terminate a person's connection if it becomes an interruption to the court proceeding. Note the following virtual room etiquette guidelines (PDF):
Ensure your camera lens is clean and free of obstructions.
Find a private / quiet room and remove any distractions.
Make sure you have adequate lighting and avoid sitting in an area that windows are behind you.
Make sure your device is on a sturdy surface and your camera is at eye level.
Place your device on mute when it is not your turn to speak.
