If you encounter any camera or microphone issues that are not recognized by the interface, please perform the following checks based on the device you are troubleshooting: 


 CameraCamera Troubleshooting 

  •    Antivirus Check: Ensure that your antivirus software is not blocking the camera. Corporate or paid antivirus programs (especially McAfee) often block system access to hardware devices.   
  •    Third-Party Verification & Exclusive Access: Verify that the camera works correctly in other applications such as Zoom or Microsoft Teams. IMPORTANT: You must completely close these applications (including from the System Tray) before starting the exam, as they can "lock" the camera and cause disconnection errors in our system.   
  •    Disconnection Errors & Physical Connection: If you receive a "Video device has been disconnected" error, check your physical connection. Unplug the camera and plug it back in, preferably into a different USB port (directly into the computer's motherboard, avoiding USB hubs or adapters).   
  •    Device Selection: If the camera suddenly disconnects, try re-selecting it from the dropdown menu in the testing interface (labeled "CAMERA DEV..."), or choose an alternative camera if one is available.   
  •    WebRTC Compatibility: Camera connectivity is established via the WebRTC component. You can test compatibility at this link. If your camera is not recognized on that page, the system will likely fail to detect it as well. In this case, try using a different camera or check for driver updates (see below).   
  •    Windows Permissions: Check your Windows settings to ensure that the application (Vix) has permissions to access the camera. For more details, see this Microsoft guide.   
  •    Updates: Ensure that your camera app and hardware drivers are up to date. Follow these instructions for manual updates.   

  •    Network Ports: Ensure that Port 443 is not blocked by your firewall.   

 MicrophoneMicrophone Troubleshooting 

  •    Antivirus Check: Ensure that your antivirus software is not blocking the microphone. Corporate or paid antivirus programs (especially McAfee) often block system access to hardware devices.   
  •    Microphone Volume: During the microphone test, please speak loudly and read the provided example text. It is important to speak clearly and at a high volume for the system to register your voice.   
  •    Third-Party Verification & Exclusive Access: Verify that the microphone works correctly in other applications such as Zoom or Microsoft Teams. IMPORTANT: You must completely close these applications (including from the System Tray) before starting the exam, as they can "lock" the microphone and prevent the testing system from accessing it.   
  •    Physical Connection: If using an external headset or microphone, check the physical connection. Unplug the device and plug it back in, preferably into a different USB or audio port.   
  •    Device Selection: Make sure the correct microphone is selected from the dropdown menu in the testing interface. If it isn't picking up sound, try choosing an alternative microphone option from the list.   
  •    Windows Permissions: Check your Windows settings to ensure that the application (Vix) has permissions to access the microphone.   
  •    Updates: Ensure your audio hardware drivers are up to date. Follow these instructions for manual updates.   

  •    Network Ports: Ensure that Port 443 is not blocked by your firewall.
