Our verdict: Iriun Webcam connects a phone camera to a Windows PC with almost no setup: start the PC server and the phone app, and it links automatically. The free version is fully usable but adds a watermark; removing it, and getting manual camera controls, requires the Pro upgrade in the phone app.
About Iriun Webcam
Iriun Webcam is made by Iriun Oy. The Windows package installs a webcam driver and a small server; the Iriun Webcam app on the phone connects to it automatically over Wi-Fi or USB, and the phone appears as a webcam and microphone in Teams, Zoom, OBS and other apps.
The desktop software is free. According to the official Android app listing, the Pro version bought in the phone app removes the watermark and ads, adds manual ISO, exposure and white balance, and lets you control the camera from the desktop. Maximum resolution depends on the phone model.
