Live Audio

When setting up audio for a VMAX standalone unit, the use of an external, amplified microphone is required. Typically, the setup process involves connecting the external microphone and enabling the preferred settings in the DVR/NVR. However, in the event that live audio does not play through the recording unit, it becomes a question if it is an issue with the microphone or if it is an issue with the connected recording unit.

This article provides a flowchart to assist with troubleshooting audio input/output issues of for standalone recording units.

 

Adjust Web Client

If you are attempting to listen to audio through your recording unit’s Web Viewer, make sure that the Audio function is enabled for the viewer. Additionally, because the DVR/NVR assigns audio to a specific video channel, full-screen the assigned channel and make sure that your computer’s audio and speaker are turned on.

 

 

Supported/Affected Devices

  • VMAX® Series (960H)
  • VMAX® A1 Series (2.1 MP)
  • VMAX® A1 Plus Series (5 MP)
  • VMAX® IP Plus Series

 

Check Camera Audio Configuration

If you cannot hear audio from an IP Camera after enabling audio on the recording unit, make sure that the Volume setting in the camera’s Web Client Video & Audio > Audio Configuration settings are set. 

For example, the DWC-MV72Wi28ATW (image below) should have its volume setting changed from 0 (default) to 1 (ON).
