Possible reasons:

  • Main menu “ENCODE” page, audio/video boxes of main and sub stream are not ticked.
  • Audio source is not correctly selected. LOCAL: the audio signal is from the Audio In port. HDCVI : the audio signal is from the coaxial cable of the camera.
  • XVR and HCVR-4M do not support front-end device audio function currently.
  • Camera’s built-in mic breaks down.
  • Loose connection.
