To ensure that audio is properly captured in Security Center, video units must use a compatible audio codec.

What you should know

  • Security Center supports the following audio codecs: G.711, G.721, G.723, AAC (8 kHz or 16 kHz).
  • Security Center supports mono and stereo audio signals. These signals must be from a single source and encoded with one of our supported codecs.
  • Security Center does not support two independent mono signals and cannot mix them to create a stereo signal. Mixing two microphone signals to get left and right channel for stereo must be performed by an audio mixer. The mixed audio then becomes a single source that outputs a stereo signal. This signal must be encoded with a support codec before being imported into Security Center.
  • A single soundtrack can be associated to multiple cameras, but multiple soundtracks cannot be associated to one single camera.


  1. From the Config Tool home page, open the Video task.
  2. Select the video unit to configure, then click the Peripherals tab.
  3. Double-click on the video unit's Microphone and select an audio codec from the Data format dropdown list.
    NOTE: The Data format dropdown only displays codecs that are supported by the selected video unit.
  4. Click Apply.
