The Audio Intercom functionality does not work after having installed Bosch VMS.
Potential Audio Intercom problems are:
Audio Intercom functionality consists of two parts:
Part 1: Output of encoder audio on the Operator Client
To get audio output on the Operator Client, follow these steps:
1. Check whether the encoder supports audio and activate it.
1.1 Open the webpage of the encoder.
1.2 In Advanced Mode, navigate to the Encoder/Audio page. Hint: If there is no audio page, then the encoder does not support audio.
1.3 On the Audio page, make sure that audio is switched "On".
1.4 On the Audio page, make sure that the Line In input levels are not zero.
1.5 On the Audio page, make sure that there is an input signal, i.e. the gauge of the Line In input should flicker.
2. Configure audio permissions in Bosch VMS Configuration Client.
2.1 Start Configuration Client
2.2 Click the User Groups tab.
2.3 Click the Camera Permissions tab.
2.4 Click to check the Playback Audio permission for the cameras to be used for Audio Intercom.
2.5 Click the Cameras and Recording tab.
2.6 Select the audio sources for the cameras to be used for Audio Intercom in the Audio column.
2.7 Save and activate the configuration.
3. Configure Windows audio playback settings.
3.1 Start some audio playback. E.g. open the Audio webpage of the encoder as described in step 1 to hear the audio signal of the encoder. Alternatively play an audio file on your Bosch VMS Configuration Client PC.
3.2 In the system tray, richt-click the audio icon and click Playback devices.
The Sound dialog opens.
3.3 Make sure that the desired playback device is set as Default Device. Make sure that there is an input signal, i.e. the gauge of the playback device should flicker.
If there is no input signal yet, proceed with step 3.4.
3.4 In the system tray, right-click the audio icon and click Open Volume Mixer.
The audio mixer opens.
3.5 Ensure that the audio level of the desired playback device is at maximum.
3.6 Make sure that there is an input signal, i.e. the gauge of the output device in the audio mixer should flicker.
4. Check audio playback in Bosch VMS Operator Client
4.1 Start Bosch VMS Operator Client
4.2 In Live Mode, open an Image pane for a camera with audio support.
4.3 In the Image pane toolbar, click the loudspeaker symbol to activate audio playback.
If no audio can be heard, make sure that the loudspeaker icon in the toolbar is activated and that the audio level in the toolbar is set to maximum.
Part 2: Output of microphone input on the encoder
To activate Intercom functionality on the Operator Client, follow these steps:
5. Configure Audio Intercom permissions in Configuration Client.
5.1 Start Configuration Client.
5.2 Click the User Groups tab.
5.3 Click the Permissions tab.
5.4 Click to check the Audio Intercom permission.
6. Configure microphone input for Operator Client.
6.1 In Windows Explorer, navigate to directory C:\Program Files (x86)\Bosch\Vms\bin
6.2 Open the file OperatorClient.exe.config with Notepad.
6.3 Navigate to line "key="MicrophoneInputNr" ADD value="0"". Make sure that the value is set to 0.
7. Configure Windows audio recording settings.
7.1 In the system tray, right-click the audio icon and click Recording devices.
The Sound dialog opens.
7.2 Make sure that the desired microphone device is set as Default Device.
7.3 Make sure that all other recording devices are disabled.
7.4 Speak into the microphone and make sure that the gauge of the microphone device flickers.
If this is the case, proceed with step 8. If there is no microphone signal yet, proceed with step 7.5
7.5 Right-click the microphone device and click Properties. The microphone properties dialog opens.
7.6 Select the Level tab and make sure that the microphone level and amplification are properly set.
7.7 Speak into the microphone and make sure that the gauge of the microphone device flickers.
If there is no microphone signal yet, make sure that you plugged in the microphone to the correct connector.
8. Check Audio Intercom functionality in Operator Client.
8.1 Start Operator Client.
8.2 In Live Mode, open an Image pane of an encoder with audio support.
8.3 Hover the mouse over the Audio Intercom icon. Note that the Audio Intercom icon changes, i.e.
a grey double-arrow is displayed. If hovering on the Audio Intercom icon does not change the icon
appearance, check whether the "MicrophoneInputNr" value is "0" as described in step 6.3.
8.4 Click the Audio Intercom icon and speak into the microphone. Hold the mouse button while speaking.
Note that the Audio Intercom icon changes, i.e. a red double-arrow is displayed while the mouse button is pressed.
8.5 Check whether audio can be heard on encoder audio output.
If the encoder audio output cannot be heard because the encoder is located on a remote site,
then open the encoder webpage as described in step 1.
8.6 Speak into the microphone while watching the Line Out gauge: the gauge should flicker when speaking into the microphone.
