Re: DWC-INTCAM02 G711U Audio Codec Fix
Known Issue: DWC-INTCAM02 G711U Audio Codec
-----------------------------------
Affected Model: DWC-INTCAM02
Release Date: January 22, 2025
-----------------------------------
Known Issue
A bug has been identified with the DWC-INTCAM02 camera’s G711U audio codec, which causes abnormal background noise.
- R&D plans to release a beta firmware version with a fix by February 15, 2025.
- The PM team will test and verify the beta firmware before official release is made available.
Audio Codec Workaround
To work around the G711A audio codec issue:
- In the DWC-INTCAM02 camera’s Setup Menu, select the “Audio” tab.
Enable the audio codec and configure the following:
- Audio Encoding: G711A
- Audio Type: MIC
- In DW Spectrum, G711U is the default audio codec and DW Spectrum will attempt to automatically change the camera’s audio/video codec to its default value.
To prevent this, in the DW Spectrum Client, open the Camera Settings menu for the DWC-INTCAM02. Navigate to the “Expert” tab and enable “Keep camera stream and profile settings.”
Apply and save the settings. DW Spectrum will keep the camera’s G711A audio codec settings.
