Microphone and Speaker

The Speaker and Microphone dialog contains the basic microphone and speaker settings of the MOBOTIX camera.

Notes:

• Click on the More button at the bottom of the dialog to display all options.
• This feature is not available for Web and Basic models.

Audio Input

• Signal Source
  • Disabled: Disables the audio input.
  • Microphone: The camera uses the microphone as audio input.
  • Line In: The camera uses the Line In pin of the D-Sub HD15 connector as audio input (only M12, D12, and V12 models).
• Select one of the following options:
  • Low sensitivity: Setting for short distances.
  • Medium sensitivity: Setting for medium distances.
  • High sensitivity: Setting for longer distances. If you select this setting, background noise may occur.
• Click on the Test button to check your setting. In order to perform this check, the speaker must be activated.

Audio Output

• Activate the speaker.
• Activate or deactivate the speaker and set the amplification.
  Value range: -30 .. 0 .. 30
• In order to check your settings, select one of the audio files and click on the Test button.

Announce Network Data

Activating this parameter will prompt the camera to announce its network configuration (IP address, network mask, MAC address; see Ethernet Interface) over the camera speaker. If the announcement is enabled, the announcement can be started by e.g. pressing the R button of the camera (to start DHCP or during runtime) or by clicking on a softbutton of the user interface.

Echo Cancellation

This parameter allows suppressing the unwanted echo that may appear during a VoIP call. The echo is created by the microphone, which also records some of the audio from the camera speaker and sends it back to the recipient of the call, thus creating an echo (back coupling). Echo cancellation suppresses this unwanted effect.

In order to optimize the quality of the echo cancellation, you can also adjust the ambient noise level. You should use the High setting if you expect a high level of noise at the camera's installation position, e.g. at a road with a high traffic volume. You should select Low, if you do not expect loud noise at the installation position of the camera.

Deactivating the Microphone

Deactivating a camera's microphone may become necessary in order to protect the privacy or for other reasons. You can permanently and irreversibly deactivate the microphone in the Speaker and Microphone dialog.

1. Click on the More button.
2. Click on the disable link that appears in the first paragraph of the explanation.
3. Follow the instructions in the Permanently Disable the Camera Microphone section.

Warning: This deactivation is permanent and removes all functions that involve the microphone and cannot be reversed even by MOBOTIX engineers.
