Continuity Camera: iPhone as a Mac Webcam

The camera in your iPhone embarrasses the webcam in your Mac — every Mac. Continuity Camera lets macOS use the iPhone's rear camera as a system-level webcam in any app: FaceTime, Zoom, Teams, OBS, all of them. No app to install, no cable required, and it comes with tricks (Desk View, Studio Light) that no actual webcam can match.

What you need

• A Mac on macOS Ventura or later and an iPhone XR or newer on iOS 16 or later.
• Both signed into the same Apple ID, with Bluetooth and Wi-Fi on.
• On the iPhone: Settings → General → AirPlay & Handoff → Continuity Camera turned on (it is by default; the same switch turns the feature off for good if you ever want that).

Wireless is the normal mode; a USB cable also works and doubles as the fix when discovery misbehaves.

Use it

1. Mount or prop the iPhone near your screen — rear cameras facing you, landscape orientation, screen off is fine. Stability matters: macOS deliberately prefers a stationary, locked iPhone over one being waved around.
2. Open your video app and pick the camera: in FaceTime, the Video menu in the menu bar lists your iPhone; in Zoom, Meet, Teams, or OBS it appears in the camera selector like any webcam.
3. The iPhone chimes, shows a camera-in-use screen, and your feed switches to conspicuously better video. Some apps even switch automatically when a mounted iPhone is detected.

The iPhone's microphone is offered the same way — as a system audio input — usable together with the camera or on its own. Pausing is on the iPhone (it shows pause/disconnect controls); undoing the whole thing is just picking a different camera in the app.

The effects: Center Stage, Portrait, Studio Light, Desk View

With the camera live, click Control Center in the Mac menu bar → Video Effects:

• Center Stage — the ultra-wide lens crops dynamically to keep you centred as you move (iPhone 11 or newer).
• Portrait — background blur, flattering in bad rooms.
• Studio Light — brightens your face and dims the background, imitating a key light (iPhone 12 or newer).
• Desk View — the party trick: the ultra-wide camera looks down and shows your desk as a top-down overhead feed, perfect for sketching or showing objects (iPhone 11 or newer). It runs as its own app-window you can screen-share alongside your face.

The microphone gets its own menu in the same Control Center panel — Mic Mode offers Voice Isolation (aggressively strips background noise; superb for calls near traffic or children) and Wide Spectrum (deliberately keeps ambient sound, for music or showing the room). Effects and mic modes persist between calls, so if a later meeting looks oddly blurred, remember Portrait is still on from last week.

Mounting is the unglamorous half of the experience: MagSafe-compatible mounts that clip to the display bezel cost little and end the phone-balanced-on-books era. Landscape, lenses level with your eyes, and the picture beats any webcam sold.

When the iPhone doesn't show up

1. Plug in a USB cable. If wired works, the camera path is fine and the problem is wireless discovery — usually Bluetooth or Wi-Fi off, or different Apple IDs.
2. Check the trio: same Apple ID on both, Bluetooth on, Wi-Fi on. Then confirm the Continuity Camera toggle on the iPhone (path above).
3. Wake and unlock the iPhone once, and take it off Personal Hotspot duty — an iPhone actively sharing internet often won't offer its camera.
4. Quit and reopen the video app — apps enumerate cameras at launch, and a phone that arrived late is invisible until they look again. Restarting both devices remains the closer.
