How to Use an iPhone as a Camera in OBS

Set up your iPhone as a video source in OBS Studio on a Mac or Windows PC, confirm it works, and fix common problems like a missing device or black preview.

You can use an iPhone as a camera in OBS Studio. How you connect it depends on your computer. On a Mac, Apple's built-in Continuity Camera feature can make the iPhone appear in OBS as an ordinary camera, with no extra software. On Windows, there is no built-in equivalent, so you need a third-party iPhone webcam app or a capture-card setup. This guide covers each route, how to confirm it works, and what each check does not prove.

The short answer

  • Mac: Use Continuity Camera. In OBS, add a Video Capture Device source and choose your iPhone from the device list.
  • Windows: Install an iPhone webcam app that includes both a phone app and a desktop component. Then add its virtual camera in OBS as a Video Capture Device, or use the app's own OBS source if it provides one.
  • Either platform: A capture card and a video adapter can bring the iPhone's display output into OBS. This works the way people connect DSLRs, but it has extra limitations, which are described below.

Seeing the iPhone in OBS's preview confirms only that OBS is receiving video. It does not show how the image will look in a recording or stream. It also does not confirm that a call app will receive the feed. Those checks are covered separately below.

Option 1: Continuity Camera on a Mac

Continuity Camera is an Apple feature that lets a nearby iPhone act as a webcam for a Mac. When it is active, macOS presents the iPhone as a standard camera, so apps like OBS can select it like any other webcam. It requires reasonably recent versions of both macOS and iOS, plus compatible hardware. This guide does not include verified version or model requirements, so check Apple's current Continuity Camera documentation if you are unsure whether your devices qualify.

Before you start

  • Sign in to the iPhone and the Mac with the same Apple Account.
  • Turn on Wi-Fi and Bluetooth on both devices.
  • Make sure Continuity Camera is enabled on the iPhone. It is in the iPhone's settings under General, in the AirPlay and Continuity section, though menu names can change between iOS versions.
  • Mount the iPhone so it stays still, with the rear cameras facing you. Continuity Camera is designed for a stationary, mounted phone.
  • Keep the iPhone close to the Mac. A cable connection for charging is optional but helps on long sessions.

Steps in OBS

  • 1. Open OBS Studio. If macOS asks whether OBS may access the camera, allow it.
  • 2. In the Sources panel, click the plus button and choose Video Capture Device.
  • 3. Name the source, for example "iPhone camera," and confirm.
  • 4. In the Device dropdown, select your iPhone. It is usually listed by the phone's name.
  • 5. Leave the default preset at first, or choose a resolution that matches your OBS canvas.
  • 6. Click OK. Resize the source in the preview so it fills the frame you want.

How to know it worked

  • The OBS preview shows a live image from the iPhone. Wave a hand to confirm the picture is moving and not frozen.
  • The iPhone shows that it is connected as a camera. Its exact on-screen indicator depends on the iOS version.
  • The image comes from the iPhone's rear camera, not the Mac's built-in camera. Covering the iPhone lens should black out the preview.

If the iPhone does not appear or the preview is black

  • Check camera permission: open System Settings, go to Privacy & Security, then Camera, and make sure OBS is allowed. Restart OBS after you change this setting.
  • Confirm that both devices use the same Apple Account and that Wi-Fi and Bluetooth are on.
  • Close other apps that might be using the iPhone camera, then reopen the source's properties and select the device again.
  • Lock the iPhone and make sure it is mounted and still, rather than lying flat or in use.
  • Remove the source and add it again, or restart OBS, so the device list refreshes.
  • If it still fails, restart both devices and confirm they meet Apple's current Continuity Camera requirements.

Option 2: A third-party webcam app (Windows or Mac)

Several third-party apps turn an iPhone into a webcam. They generally pair an iPhone app with a desktop program or driver, and they connect over Wi-Fi, USB, or both. Features, image quality options, watermarks, and pricing vary by app and change over time. This guide has no verified details on any specific app, so compare current listings and confirm that the app supports your operating system and OBS before you rely on it.

General setup

  • 1. Install the app on the iPhone and the matching desktop component on the computer, following the developer's instructions.
  • 2. Connect the phone the way the app recommends. A USB connection is usually more stable than Wi-Fi when the app supports it.
  • 3. Open the iPhone app and the desktop component, and confirm they detect each other.
  • 4. In OBS, add a Video Capture Device source and pick the app's virtual camera from the Device list. Some apps provide their own OBS plugin or source type instead. If so, use that and follow the app's instructions.
  • 5. Check the preview for a live, moving image from the iPhone.

If the device is missing on Windows, check the camera privacy settings in Windows Settings. Make sure desktop apps are allowed to use the camera, then restart OBS. Also make sure the desktop component is running before you open OBS.

Option 3: Capture card and video adapter

This works like using a DSLR's HDMI output as a webcam. An adapter that matches the iPhone's port sends its video output to an HDMI capture card, and OBS reads the card as a Video Capture Device. The catch is that the iPhone sends its screen, not a clean camera feed. If you open the Camera app, its buttons and overlays will usually appear in the video. To get a clean image this way, you would need a camera app that offers a clean display output. Check that capability before buying hardware. For most people, Option 1 or Option 2 is simpler.

Checking the result beyond the preview

Each check below confirms one thing and leaves something else untested.

Check | What it confirms | What it does not confirm
Live image in the OBS preview | OBS has camera access and is receiving video | Recorded or streamed quality, or whether other apps can see the feed
Short test recording, played back | How the video looks after encoding, including smoothness and sharpness | Network performance during a live stream or call
OBS Virtual Camera selected in a call app's preview | The call app receives the OBS output | How the video looks to other participants on a real connection
Short test call with someone else | What others actually see under real conditions | Performance on other days, networks or lighting

To use the iPhone feed in a video call app, click Start Virtual Camera in OBS's Controls panel. Then choose the OBS virtual camera as the camera in the call app's settings. If the call app shows a black or placeholder image, start the virtual camera first, then reopen the call app's camera settings.

Audio: treat the microphone separately

A working iPhone video feed does not mean the iPhone's microphone is being used. With Continuity Camera, the iPhone may also appear as a microphone option. Third-party apps vary in whether they pass audio. In OBS, add the microphone you want under Audio Input Capture, or set it in OBS's Audio settings.

  • Detection: The microphone appears in OBS's device list.
  • Input activity: The mixer meter for that source moves when you speak.
  • Intelligible sound: A test recording, played back, sounds clear, without echo, distortion or dropouts.

This guide has no verified target input levels for this setup. As a general practice, speak at your normal volume and keep the meter's peaks out of the red zone, which indicates clipping. Then confirm by listening to a recording rather than relying on the meter alone. Video and audio from different devices can also drift out of sync. If lips and speech don't match in your test recording, use the Sync Offset option in OBS's Advanced Audio Properties to adjust the audio.

Practical tips for a steady image

  • Use a phone mount or tripod. Small movements are very noticeable on camera.
  • Keep the iPhone charging during long sessions, because continuous camera use drains the battery.
  • Silence notifications on the iPhone, for example with a Focus mode, so alerts don't interrupt the session.
  • Match the camera's resolution to your OBS canvas so the image isn't stretched or cropped unexpectedly.
  • Face a light source rather than sitting with a bright window behind you. Better lighting improves image quality more than most settings changes.
