Frequently Asked Question

ITVDesk can attach audio to supported video streams so the VMS/NVR can record video and sound together. Audio is useful for operator monitoring, training, audit recording and incident review.

Common audio sources

• Microphone input.
• Webcam or capture-device audio.
• System audio or Stereo Mix where supported by the Windows audio driver.
• Audio-only source when no video stream is required.

Setup checklist

• Select the audio device in ITVDesk.
• Confirm OS permissions and audio driver availability.
• Choose a codec and bitrate compatible with the VMS/NVR.
• Test live view and recorded playback, not only preview.

Troubleshooting

• If video works but audio does not, verify codec support in the VMS/NVR.
• Check whether the audio device is already used exclusively by another application.
• Confirm that the recorder has audio enabled for that camera/channel.
