Notice - read carefully!
This page is intended to familiarize yourself with setting up and testing the proper operation of Supervisor on your computer.
Supervisor lets you stream two cameras you have connected to your computer at the same time, as well as your desktop.
You do not need to install any additional software on your computer for this broadcast.

However, you must allow your web browser to access the cameras, microphone, and desktop capture.

An updated web browser is required for Supervisor to work properly. Recommended internet browsers are Mozilla Firefox, Google Chrome, Safari or Microsoft Edge.

Click the red Test cameras and broadcast button to start checking and setting up your computer. You will be asked to grant Supervisor access to the camera (s) and microphone. You'll then click the Broadcast buttons in the three windows below. This will test and set up broadcasting from your cameras and desktop sharing. When enabling desktop (screen) sharing, you must enable Entire desktop (screen) sharing, not just the browser window. You will no longer have to click the test button during live operation and you will be prompted to grant access to cameras, microphone and desktop.

You can try testing and setting up your computer again by reloading this page.

Warning: For live operation, the same computer and web browser must be used as for the successful test. We do not recommend using a VPN connection during heavy traffic. Your firewall must allow the entire domain as well as subdomains and TCP ports: 80,443,5080,1935,8554,8081,8083,6262 and UDP: 40000-65535.
This window will display a video of your Supervisor (eg lecturer, examiner, etc.)
This section displays basic information about the Supervision (consultation, exam) such as name, date, time. It is important to check your email.
This window displays the discussion of all participants. The discussion is only active if the Supervisor broadcasts.

Follow all instructions below to set up all cameras.

Cam. 1

Face camera

Camera 2

Computer desktop

Camera 3


In this window you start broadcasting your first (main) camera. It should point to your face.

At the top of this window, select the camera and microphone you want to use for the broadcast. If you have an external camera, you need to connect it to your computer before launching the Internet browser, resp. you open this page.

After selecting the camera and microphone, you can click the "Broadcast" button. The image from your camera should appear in the middle of this window. At the same time, if you're talking, the microphone indicator on the top right of the camera image should flash green. If you see the image from the camera and the microphone indicator flashes, then the settings of this camera are OK and you can continue with the desktop (screen) sharing settings.

Information for Mac OS users (Apple):
It may be necessary to grant access to the camera to a web browser before using the camera. You will either be prompted to grant this permission automatically, or you can do so in System settings -> Security & privacy -> Privacy -> select "Camera" on the left -> there is a list of apps on the right , which have access to the Camera. Your internet browser must also be on this list here.
It may be necessary to make the same settings for the Microphone in addition to the Camera.
In this window, you start sharing your desktop (screen).

You no longer select a camera when sharing your desktop. It's important in this case to set up a FULL desktop (screen) share (especially for Mozilla Firefox). Every internet browser has this setting done a little differently.

Click the "Broadcast" button to start testing the desktop share. Here you need to keep a close eye on what the browser will ask you. As already mentioned, you need to be careful to allow the browser to capture the entire screen, not just the web browser window. If this doesn't work for the first time, you can reload the entire page and try again.

If you see an image of your desktop (screen) in the window, the setup has been successful and you can proceed to set up the secondary camera.

Information for Mac OS users (Apple):
You may need to grant your web browser access to the Screen Recorder before you can share your desktop. You will either be prompted to grant this permission automatically, or you can do so in System settings -> Security & privacy -> Privacy -> select "Screen capture" on the left -> there is a list of apps on the right who have access to screen capture. Your internet browser must also be on this list here.
In this window you start broadcasting your second (secondary) camera. This camera should point to the room you are in so that it is visible as you work behind the computer.

In order to use this secondary camera effectively, you also need to have a second external camera connected to your computer. If you do not have a second camera, then one solution is to place another computer with a camera in the room (preferably a laptop with a camera). In this laptop, you will open a link from the e-mail that is intended for "Camera 3" and then turn on the transmission of the secondary camera via this laptop.

The second option is to use a mobile phone for broadcasting, in which you will open this link (or a separate link for camera 3, which you will receive in the invitation). In order not to turn off your mobile phone screen (which will also interrupt the image transmission), it is necessary that you turn on the camera output to the full screen of the mobile phone (fullscreen).

Run each Camera (1,2,3) on only one device. This means that if you run Camera 1 and Camera 2 (desktop) on your computer and then run Camera 3 on your mobile phone, then don't start Camera 3 on your computer anymore .

Information for Mac OS users (Apple):
Same as Camera 1.
