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.
To configure a video unit's audio codec:
-
From the Config
Tool home page, open the
Video task.
-
Select the video unit to configure, then click the Peripherals
tab.
-
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.
-
Click Apply.
