Application installation

To start using the client application, download it from the of your (you can confirm its address with your administrator) or from the official website page:

Before starting to use the client application, ensure that all operating system updates are installed and the video driver for the graphics adapter is updated to the latest version. Drivers should only be downloaded from the official manufacturer’s website: .

The following demonstrates how to use the client applications, using as an example.

Connecting the application to the server

Upon the first launch, the application will automatically detect on the local network and display a window for connecting to it.

Only 4.5 + instances can be automatically detected.

By default, the application connects to the cloud service.

To switch to the corporate , press the button.

Next, in the window that opens, switch to option in the field and enter the IP address or FQDN of your server. Click the button.

If the connection is successful, a message like Connected to server.company.com will be displayed at the top in the line.

Signing in

In the authorization window, enter your (username) and , which you registered with. You can verify these details with your server administrator.

Then click

Application settings

Video and audio

Go to the menu in the application window. Then, under the tab, select the camera, speakers, and microphone.

In section (below the microphone selection), there are two checkboxes related to audio processing:

  • ;
  • .

These checkboxes are marked by default, and it is helpful in most cases. However, if you use a recording device with integrated echo cancellation/AGC mechanisms, we recommend disabling these options in the application to avoid conflicts between algorithms.

For the echo cancellation algorithm to function properly, you can conduct an audio test to measure your device's latency. To do this, click the button at the bottom of the window.

During the testing, you will hear several audio signals from the selected playback device. When the test is successfully completed, the time of delay will be displayed.

You can retake the audio test by clicking the button, which will appear after the first successful test instead of the button.

To select the desired sound notifications from the application and the device for their playback, go to the tab.

Virtual backgrounds

Let's specifically highlight the additional feature of replacing the background in the image captured from the webcam. This feature is available for any computer that meets the general and can be used for both one-on-one video calls and group video conferences. It utilizes chroma key image compositing technology.

Background replacement can be useful in various cases. For instance, during a webinar, you might want to display a corporate logo in the background, or use a related image during a video lecture.

You can achieve a better result if you are using a solid background of classic colors for chromakey: blue, green, purple. Small color gradients and variations are acceptable if they are shades of the main background color, i.e. close to it.

To change the background, take the following steps:

  1. Go to the section.

  2. Use the button to select an image to change your background. It will be scaled to the width of your video window, so if you want to avoid cropping, choose an image that matches the aspect ratio of your webcam.

  3. Check the box . Immediately after, you will see the result in the video preview window.

Network

In section , you can change your server or connect to .

When the checkbox in field is selected (default is unchecked), the connection during a will be routed through the server.

You can check the list of available servers for connection using the link .

Sections and will allow .

Preferences

By navigating to section , you can configure the application to start automatically when the operating system launches (enabled by default).

The checkbox (checked by default) allows you to connect to the server without having to enter your login and password each time. The application will remember the login settings for different servers and automatically authorize you when connecting to one of them.

If you want to change the server, go to the menu , specify the desired server in the section, and click . It is not necessary to disconnect from the current server using the menu item beforehand; otherwise, automatic authorization will not be available the next time you connect to this server.
