Requirements for listening to incoming audio

To listen to incoming audio from your cameras, you must have:

• A microphone attached to a camera.

  When a camera in your surveillance system has a microphone attached, you can play audio without any additional settings needed. The audio icon on the camera toolbar shows whether the audio feature is available.

• Sufficient user permissions.

  Access to the incoming audio feature may be restricted depending on your user permissions. Ask your system administrator if in doubt.
