/docs/group-user/media/settings/camera/en.png

By activating the Enable automatic framing option, the image from your camera will be automatically cropped to keep you at the center of attention.

The Enable face tracking option highlights all people in the frame with a colored box.

In the Device management section, you can add RTSP and VNC sources from the address book. These sources can then be used as your camera.

# Camera image

This section allows you to configure the image from your camera; you can edit:

  • Brightness – camera image brightness;

  • Contrast – camera image contrast;

  • Auto exposure – this parameter affects the camera image's automatic exposure settings:

    • Aperture Priority Mode – auto exposure control mode;
    • Manual mode – independent configuration of the camera exposure settings.

  • Saturation – the color saturation level in the camera images;

  • Exposure Time, Absolute – this parameter affects the settings for the maximum exposure time in the camera images;

  • Hue – this parameter affects the camera image hue settings. It will be adjusted if Manual mode is selected in the Auto exposure parameter;

  • White Balance, Automatic – automatic white balance;

  • Focus, Automatic – automatic focusing;

  • Gamma – overall image gamma;

  • Gain – this parameter affects the gain (sensitivity) settings of the camera image;

  • Power Line Frequency allows the camera to synchronize its image capture frequency with the power supply frequency. Available options are: 50 Hz, 60 Hz, and off;

  • White Balance Temperature – this parameter affects the white balance temperature settings in the image. The setting is available if the Off mode is selected in the White Balance, Automatic section.

  • Sharpness – adjusts the clarity of the camera image;

  • Backlight Compensation – compensating for backlight in an image;

  • Focus, Absolute – camera focus settings. This parameter can be adjusted if the Off mode is selected in the Focus, Automatic section.

Additionally, the following settings are available for PTZ cameras:

  • Pan, Absolute – PTZ camera pan setting. This parameter can be adjusted if the Off mode is selected in the Focus, Automatic section.

  • Tilt, Absolute – PTZ camera tilt adjustment. This parameter can be configured if the Off mode is selected in the Focus, Automatic section.

  • Zoom, Absolute – this parameter affects the zoom settings of the camera image. It can be adjusted if the Off mode is selected in the Focus, Automatic section.

  • Zoom, Continuous – this parameter affects the continuous zoom speed. You can configure this parameter if Off mode is selected in the Focus, Automatic section;

  • Iris, Absolute – this parameter affects the settings for the maximum amount of light entering the camera sensor. It can be adjusted if the Off mode is selected in the Focus, Automatic section;

  • Pan, Speed – this parameter affects the camera's image rotation speed settings. It can be adjusted if the Off mode is selected in the Focus, Automatic section. The further to the right the slider is and the higher the number, the faster the speed;

  • Tilt, Speed – this parameter affects the tilt speed settings of the camera image. It can be adjusted if the Off mode is selected in the Focus, Automatic section. The further to the right the slider is and the higher the number, the faster the speed.

# Audio Settings

Go to the Devices → Audio section to adjust microphone and speaker settings.

/docs/group-user/media/settings/audio/en.png

For audio input, you can:

  • select Microphone;

  • enable or disable it;

  • adjust microphone gain;

  • set the echo cancellation mode to 50 Hz filter only, Half-duplex, Full-duplex, and Custom;

  • enable Noise suppression mode;

  • Enable Microphone gain control (the system automatically adjusts the microphone gain). This setting is available if one of the echo cancellation modes is selected.

  • perform a microphone test.

And for audio output, you can:

  • select Speakers;

  • enable or disable audio sources;

  • adjust the volume;

  • conduct a sound test.

Complete speakerphones come with built-in echo cancellation, so you need to set the software echo cancellation mode to Disabled in the settings.

When enabling echo cancellation, select the appropriate mode:

  • 50 Hz filter only – eliminates low-frequency sounds, such as stomping and table knocks;

  • Half-duplex is effective when the microphone is positioned very close to the speaker;

  • Full-duplex – the primary operating mode;

  • Custom – contains parameters optimized for a specific device.

Enabling software echo cancellation will be effective when outputting audio to a TV or external speakers.

# Video settings

Go to the Devices → Monitor section; this option allows you to set the parameters for capturing and displaying the image on one or more screens.

# Monitor Management

In this section, you can configure the connected screens.

/docs/group-user/media/monitor-management/en.png

If your setup includes 2 screens, you can choose which one will be used as the primary or secondary display.

In the HDMI Mode section, you can set the resolution and frame rate for the terminal interface display.

The Rendering resolution option is responsible for the layout resolution in calls (Auto, FullHD 1080p, and UltraHD 2160p).

The UltraHD 2160p resolution for video layout in calls is not available in all configurations. When displaying the layout on 2 monitors, the rendering resolution of each layout is limited to FullHD 1080p.

Below, you can Detect video outputs and perform a Monitor test (useful for screen calibration).

# Presentation

In this section, you can add RTSP and VNC sources for presentations. The process of adding presentation sources is described in the relevant section of the documentation.

# Layout

Go to the Video → Layout section, where you can configure the video layout for calls.

/docs/group-user/media/settings/layout/en.png

By default, the Self-view option is set to Hide. Set the option to Show to see the self-view in the video layout.

To display microphone sensitivity in participant windows, enable the Show volume indicators option.

/docs/group-user/media/volume_level/en.png

Scaling mode – the mode for cropping participants' video windows. Available options:

  • Auto – depending on the participants' video, the terminal automatically selects the cropping mode;

  • Scale to fit video – participants' video windows are fully displayed in the video layout;

    /docs/group-user/media/scaling_video/en.png

  • Crop to fit window – participant video windows are cropped to fit the width of your screen.

    /docs/group-user/media/scaling_window/en.png

If you activate the Enable overlay mode option, participant videos will be displayed over the main video window.

/docs/group-user/media/overlap/en.png

Below is the Overlay coefficient setting, which controls the spacing between video windows. Here is how the layout looks with a 25% overlay:

# Diagnostics

This settings section is designed for monitoring the operation of TrueConf Group and its network connection.

# System Monitoring

This subsection allows for real-time monitoring of key system performance parameters: RAM and storage usage, as well as network and CPU load.

/docs/group-user/media/monitoring/en.png

# System log

Here you can export detailed logs of events, processes, and errors occurring in the system to a USB drive. Refer to this section if you encounter any issues while using the terminal. We recommend leaving this procedure to your administrator.

# Ping

This section is designed to test and determine the connection latency to servers, routers, and other devices. Enter the required IP address and click the Test button. Detailed information will then be displayed.

/docs/group-user/media/ping/en.png

# Tracing

If you need to trace the route of packets from your device to the target node, use the built-in Trace tool. Enter the required IP address and click the Test button.

# Network Packet Log

The network packet log allows for recording the network traffic passing through TrueConf Group. Only an administrator can download and view the logs using the control panel. It is also possible to download them to an external USB drive.

You need to provide traffic log files when contacting technical support.

# Power Supply

In the Power → Power management section, you can:

/docs/group-user/media/power_management/en.png

  • Go to sleep mode. Your administrator can configure the sleep mode, for example, to activate it by pressing the power button;

  • Shut down the endpoint ;

  • Press Restart OS. After pressing, the operating system and the terminal's visual interface (video conferencing system) will restart.

  • Restart the endpoint Clicking this will quickly restart the terminal's application software.
