Procedure

The Zoom Rooms 3.0 plugin allows you to select 3rd party cameras that are attached to the host PC via USB. When you open the Zoom app with cameras connected, the 3rd party cameras populate in the Camera Lines section of the plugin's Camera Control tab. If you want to auto-select a camera from the Camera Lines list, you can use the Camera Lines box as a control component in a snapshot bank. From here, you can use logic to trigger a specific camera to be selected.

This comes in handy if you want to use signal presence from a microphone to select a specific camera in the room.
