Audio

Using Macula Monitor application, you can listen to audio streams from cameras, play back recorded audio, as well as talk back to the cameras. Recorded audio streams are also available when you export the recordings.

Two-way audio is also supported for the Macula Mobile application; please refer to the mobile application user guide.

In order audio stream to be available in Macula Monitor, there are a few conditions:

• the device, from which your selected channel originates, must be capable of sending/receiving audio and this feature must be enabled and set to G.711 codec via device Web interface.

• the device, from which your selected channel originates, must have audio support implemented in Macula; please contact GSF if you have doubts.

• audio function must be enabled for the target channel via Macula Console, please check the settings via Macula Console according to the Audio section of the Macula administration user guide.

Without these, audio IN/OUT controls will not be available for the selected channel.

Make sure that the speakers and the microphone on your workstation are properly installed and are operable in order to be able to use the audio functionality in Macula Monitor.

Live View

Audio IN/OUT toggle overlay controls are enabled by default for the live view and become available when you select a viewport by clicking on it. You can change this preference via Macula Monitor main menu by going to Edit -> Settings: you will find the related settings in the Display controls section of the Viewport overlays tab. The available display options are: always show the overlay control, show only if the viewport is selected and disable the overlay control.

By default, live audio is OFF; in order to listen to the incoming audio, click the speaker overlay control so that it becomes yellow: if audio functionality has been enabled on the device side and in Macula Console, you should be able to hear the sound coming from the target device.

In order to send some audio back to the camera, press and hold the microphone overlay control (it will also turn yellow, indicating that reverse audio is active) to speak, then release the control when you have finished speaking.

Playback

If a channel has incoming audio recording enabled, it will be displayed in the archive playback mode. On the timeline, recorded audio is denoted by a red line, which slightly wider than the grey line (video stream) and the white line (motion).

By default, audio is muted; in order to enable it, select your desired channel simply by clicking on the picture (viewport) and then use the speaker overlay control to turn audio ON. Note that the overlay control will only be available if there is some recorded audio for the selected channel. Then, start playing back the recordings as usual to play both video and audio streams. Use your Windows volume mixer to adjust the sound volume.
