Listening on the Client to sound from a camera microphone

If a microphone is a part of an IP server, you must specify the camera to which it is matched in the parameters of this microphone. When you do this, the Microphone object becomes a child of the specified Camera object.

Attention!

When you reassign a microphone from one camera to another, all previously recorded audio archive is also transferred and later played back when you view the archive of the new camera.

This setting is used during synchronized video and audio monitoring of a situation as well as during synchronized video and video recording to the archive (see Audio Monitoring).

In all other cases, the Microphone object is automatically displayed in the object tree as a child object of a camera.

To configure the Microphone object, do the following:

  1. Go to the Devices tab.
  2. Select the Microphone object in the object tree. If necessary, you can change the values of the parameters that are listed in the table:
