Using the Zoom Room Custom AV Controller app

The Zoom Rooms Custom AV Controller app (CAVZRC) is a separate Zoom Room Controller intended to be used by AV integrators, installers, AV managers, IT, and production operators. With the introduction of additional inputs and outputs, this controller provides technical users with advanced AV controls, real-time room management, and remote multi-room pairing capabilities. This controller facilitates Zoom Room configuration when using NDI, Hardware I/O SDI, and Dante, and also provides a technician-focused interface for real-time control of the Custom AV outputs, for example in an auditorium or broadcast setting.
