# Configuring Audio for Non-Verkada Channels

Verkada Command supports audio for compatible third-party cameras on non-Verkada channels. To use audio, the camera must conform to ONVIF Profile S and the audio codec requirements.

{% hint style="warning" %}
Audio configuration is available only for cameras that fully support ONVIF Profile S, including audio profile configuration calls.
{% endhint %}

***

### Before you begin

The camera must meet the requirements below before you configure audio. See [Add a non-Verkada camera to a Command Connector](https://help.verkada.com/command-connector/configuration/add-a-non-verkada-camera-to-a-command-connector) for adding cameras.

#### ONVIF Profile S conformance

The camera must be ONVIF Profile S conformant. Confirm that your third-party camera meets all technical requirements.

* Refer to the camera manufacturer's specification sheet or datasheet.
* Look for "ONVIF Profile S" certification in the camera documentation.
* Verify the camera firmware version supports Profile S features.

#### Audio profile configuration support

The camera must implement the ONVIF Profile S calls for audio profile configuration. This includes support for:

* `GetAudioEncoderConfigurations`
* `GetAudioEncoderConfiguration`
* `SetAudioEncoderConfiguration`
* `GetAudioEncoderConfigurationOptions`

#### G.711 mu-law codec

The camera must support the G.711 mu-law (PCMU) audio codec through the ONVIF Profile S audio configuration calls. This codec provides 8-bit audio encoding at 64 kbps and is the standard for audio in ONVIF Profile S cameras.

{% hint style="warning" %}
Cameras that do not support G.711 mu-law through ONVIF Profile S calls cannot be configured for audio, even if they support other audio codecs.
{% endhint %}

## Configuration

{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Cameras.**
{% endstep %}

{% step %}
**Select the non-Verkada channel you want to configure.**
{% endstep %}

{% step %}
**At the top right, click Settings.**
{% endstep %}

{% step %}
**Under Device > Audio, toggle on Enable Audio.**

Wait for Verkada Command to detect available audio configurations via ONVIF.
{% endstep %}

{% step %}
**Open the camera's live view.**

1. Verify the audio indicator appears in the video player.
2. Play live audio to confirm the configuration.
   {% endstep %}
   {% endstepper %}

## Troubleshooting

#### Audio option not available

**Issue:** The **Enable Audio** toggle is grayed out or not visible in camera settings.

**Solution:**

* Verify the camera is ONVIF Profile S conformant.
* Confirm the camera firmware is up to date and includes Profile S support.
* Check that the camera has implemented audio profile configuration calls.
* Check that the camera supports G.711 mu-law.
* Re-add the camera to Command to refresh ONVIF capabilities detection.

#### G.711 mu-law verification

**Issue:** The camera supports audio, but audio does not initialize after enabling audio.

**Solution:**

* Log in to the camera's web interface by navigating to its IP address in a browser.
* Verify the camera supports G.711 mu-law through the camera's web interface or ONVIF audio settings.
* Check if the camera requires a specific configuration mode or profile to expose G.711 support.
* Contact the camera manufacturer to confirm G.711 mu-law support via ONVIF Profile S.

#### Audio stream fails to connect

**Issue:** Audio configuration saves successfully, but no audio streams in live view.

**Solution:**

* Check that firewall rules allow ONVIF audio streaming ports (typically RTP/RTSP ports).
* Confirm the camera's audio input is not muted or disabled in the camera's native interface.
