A few weeks before QSC released a plugin to aid with recalling camera presets to follow people around the room, I made my own.

You’re probably better off using their one, but there are still situations where I might choose to use mine.

When a single control pin is activated, the associated output pin will be activated. When either no input pins, or multiple input pins are activated, it will activate the master preset output.

This allows a view of the room to be selected for multiple people speaking, or a closeup for a single person speaking.  The time control allows you to adjust the sensitivity to avoid the camera switching when someone coughs or bangs on the desk.
