Your phone's camera is usually much better than a laptop webcam. Here is how to use it on a computer, and how to check the result with the webcam test.
iPhone with a Mac: Continuity Camera
On macOS Ventura or later with iOS 16 or later, an iPhone near your Mac can act as a webcam with no extra app. Mount the phone in landscape on top of the screen, with the rear cameras facing you, and choose the iPhone as the camera in Zoom, Teams, FaceTime or your browser. Both devices need to be signed in to the same Apple ID with Wi-Fi and Bluetooth on.
Android with Windows
Recent Windows 11 updates can use a linked Android phone as a webcam through Phone Link (Mobile devices settings). Turn on Manage mobile devices in Settings > Bluetooth & devices > Mobile devices, link the phone, and allow it to be used as a connected camera. It then appears as a camera in apps.
Any phone with any computer: webcam apps
Apps such as Camo, Iriun and DroidCam install a small app on the phone and a driver on the computer. Connect by USB for the best quality and lowest delay, or Wi-Fi for convenience. Free versions often limit resolution or add a watermark.
Just joining from the phone
You can also join the call from the phone itself in the Zoom, Teams or Meet app. Hold the phone sideways: held upright, people on laptops see a wide slice from the middle of your tall picture, which can cut off your head and chin. The webcam test shows this crop when you open it on your phone.
Tips for a good picture
- Use a tripod or a clip mount at eye level. Don't lean the phone against a mug.
- Use the rear camera when you can. It is sharper than the selfie camera.
- Plug the phone in. Video drains the battery fast.
- Turn on Do Not Disturb so notifications don't interrupt.
