Using NDI Webcam Input as Video Source

The NDI webcam input creates a virtual webcam source from available NDI video sources on your network. The virtual webcam can then be used with any software that requires a webcam. This tool enables you to use an NDI source as a webcam source for your video conferencing apps, such as zoom.

When installing NDI tools, you can opt to let the NDI webcam input ‘run at startup.’ The application can be found in the system tray when it’s running and you can click on it to open the settings menu. In this menu, select any NDI source you want to use as a virtual webcam.

Other NDI tools include the studio monitor, which enables your computer to display any NDI video source, like a China PTZ camera that is available on your LAN and the NDI screen capture, which captures the screen of your computer and makes it available as a video source.

How to Use OBS with Zoom for Audio

Using OBS with Zoom for audio is not as straightforward as the virtual camera connection because this process requires two software. But following the steps below you can easily make this audio link.

Step 1: First, download and install the OBS plug-in ‘Audio Monitor’ from the website. Then, you need to download the virtual audio cable software on your computer. After installing the two software, restart your computer. 

Step 2: After restarting, click on the audio option on your computer settings. Choose Cable-A Output (VB-Audio Cable A) as the microphone and set Cable-B Input (VB-Audio Cable B) as your speaker in Zoom. Then, click ‘OK.’
