These days with increasing use of web-meetings, the web-cam becomes a very important accessory for day-to-day use. Most in-built webcams on laptops do not have a very good resolution, necessitating deployment of an external webcam through the USB port. However, you may have observed that the camera on your phone is far superior.
The Iriun app, on the Play Store and App Store, allows you to use your superior mobile phone camera on your PC or Mac, wirelessly. The setup is as simple as it could be. Just install the app on your phone and on your PC or Mac on the same wireless network. Run Iriun on your phone. Then start your web-meeting software (Zoom / Teams / Skype) and select Iriun webcam as your camera. And, magically, your phone camera is enabled and available online! Excellent quality and basic options to use it in portrait or landscape mode and also the choice to use the front or back camera are available. With a powerful, speedy Wi-Fi connection, it can broadcast in 4k mode also!
A very useful accessory for your online toolkit!
