Audio (configuration)

Select the microphone you want to listen to audio from.

If the Microphones list displays Missing hardware on local PC, your computer does not have a microphone installed or the microphone is disabled. If the list displays No microphone sources, no microphones attached to cameras are available.

Select to mute either microphones or speakers.

Select the speaker you want to talk through.

If the Talk button is disabled, your computer does not have a speaker installed or the speaker is disabled. If the list displays No speaker sources, no speakers attached to cameras are available.

If your surveillance system has speakers attached to multiple cameras (and you have the necessary user permissions to access them), you can talk through all the speakers simultaneously by selecting All speakers from the Speakers list.

Click and hold down the mouse button for as long as you want to talk.

The meter indicates the level of your voice. If the level is very low, you may need to move closer to your microphone or adjust your audio settings in Windows. If the Level meter shows no level at all, check that the microphone is connected and correctly set up.

When you select a camera or view, the corresponding microphone and/or speaker is also selected by default. However, if you want audio for a specific camera regardless of the ones you are viewing, you can select Lock to selected audio devices.

Example: You need to listen and talk to a crime victim through microphones and speakers attached to camera A, but you also urgently need to view cameras X, Y and Z, some of which are displayed in different positions in the view. By selecting Lock to selected audio devices, you can communicate with the victim on camera A while viewing the other cameras at the same time.

If your surveillance system contains large numbers of microphones and/or speakers, the lists from which you select microphones and speakers in the Audio pane can be very long. To avoid this, you can limit the lists to only contain microphones and speakers relevant to your current view by selecting List only devices from current view.

In this context, current view also includes any views you have open as floating windows and on primary and secondary displays (see Working with detached windows).
