Since we implemented Zoom via Logitech rally bar, based on Android OS, there are options for camera control in the rally. This options are available only in the conference rooms mentioned in the title of the article. 

First, the user must enter the meeting ID under Start new meeting. After that, additional screen pop up with the following options

When the user select Camera control a second window comes up : 

If the participants in the room are not to many the best option is Speaker focus. The camera will respond in 2-3 seconds based on a voice or movement or both and will zoom the face of the speaker. If the participants are more than  4-5 people at this point, the Auto framing is the best option. The camera will focus and zoom on a selected group of people. If the meeting is Hybrid type - people in the room and remote participants - the 3rd option would be best. If not at this options fit the meeting the last option is the manual remote control to be used.
