Have you ever wished your PC webcam was as sharp as the camera on your phone? The good news is that you can easily turn your phone into a high-quality webcam and microphone for your computer – and the best part? It’s completely free.

Why Use Your Phone as a Webcam?

Most phone cameras outperform standard webcams in terms of clarity and resolution. By using your phone, you can drastically improve video quality for meetings, recordings, or live streams.

Step-by-Step Guide:

Here’s how to set it up:

1. Download OBS Studio

  • Head to OBS Studio’s website – obsproject.com – and download the software for your operating system.
  • Follow the installation steps.

2. Use Video Ninja to Connect Your Phone

  • Go to Video Ninja – video.ninja – on your PC.
  • Click Create reusable invite in the top right-hand corner.
  • Customize the settings and enable video effects if you’d like.
  • Generate an invite link and QR code.
