Two-way audio allows a compatible VMS/NVR or ONVIF client to send audio back to the ITVDesk computer. This is useful for operator communication, announcements and controlled talk-back workflows.

Requirements

• A VMS/NVR or ONVIF client with audio backchannel support.
• A working playback device on the ITVDesk computer.
• Correct operating system audio permissions and drivers.
• Compatible codec/profile settings on both sides.

Setup checklist

• Enable audio backchannel support in ITVDesk.
• Confirm the output device used for playback.
• Refresh or re-add ITVDesk in the VMS/NVR.
• Test talk-back audio from the VMS/NVR user interface.

Compatibility note

• Normal audio streaming and audio backchannel are separate features; a recorder may support one but not the other.
