A successful camera preview at the start of a call is only part of a dependable setup. If the camera is your iPhone, using or unlocking that phone can interrupt the session. Rehearse the arrangement before the meeting depends on it.

Apple’s webcam requirements include an iPhone XR or later with iOS 16 or later, and a Mac using macOS Ventura 13 or later. Both need the same Apple Account with two-factor authentication, enabled Wi-Fi and Bluetooth, and Continuity Camera enabled on the iPhone.

Neither device should be sharing its internet connection. Wireless use also excludes simultaneous AirPlay or Sidecar on the Mac. A USB connection requires the iPhone to trust the Mac. Check these conditions before buying a mount or changing application settings.

Test the intended picture and sound

Secure the phone near the Mac, locked, with its rear cameras unobstructed and facing you. Select the iPhone in the meeting application’s camera controls if it is not chosen automatically. The microphone is a separate selection; choosing the camera does not mean you must also use its microphone.

Use the application’s preview or supported test feature with harmless content. Check framing, lighting and sound using the equipment that will be present during the real meeting. Keep the mount stable without balancing the phone where it could fall onto the display.

Practise a recoverable interruption

Apple states that unlocking the iPhone pauses Continuity Camera. In the rehearsal, unlock it, then lock and mount it again. You may need to restart video or audio in the application. Check the selected camera and microphone after resuming.

Observe what other participants would see during the interruption using an agreed test session if necessary. Do not assume that a paused picture has returned simply because the phone is locked again.

Keep the tested recovery sequence beside your meeting notes. Plan how you will handle phone use during the call and which alternative camera is available. The useful result is a setup you can restore calmly, with the picture and sound verified together.
