How to Use an iPhone as a Webcam in OBS

Set up your iPhone as a camera source in OBS Studio on a Mac or Windows PC, confirm the video is live, and send it to video-call apps.

The short answer

You can use an iPhone as a camera in OBS Studio by making the phone appear to the computer as a video device, then adding it to OBS as a Video Capture Device source. How you make the phone appear depends on your computer. On a Mac, Apple's built-in Continuity Camera feature can present the iPhone as a webcam with no extra app, as long as both devices meet Apple's requirements. On Windows, Apple provides no built-in equivalent, so you need a third-party webcam bridge app. A bridge app is software that runs on both the phone and the computer and passes the phone's video to the computer, usually over USB or Wi-Fi.

One distinction changes what you need to do. If you only want the iPhone image inside OBS for recording or streaming, adding the source is enough. If you also want that OBS scene to show up in Zoom, Teams, Google Meet or a browser call, you then need to start OBS's Virtual Camera and pick it as the camera in the call app.

Before you start

  • OBS Studio installed and updated on the computer.
  • On a Mac: an iPhone and macOS version that support Continuity Camera. Check Apple's current compatibility list, because this guide cannot confirm specific models or version numbers.
  • On a Mac: the iPhone and Mac signed in to the same Apple Account, with Wi-Fi and Bluetooth turned on for both. A USB cable is optional and can give a more stable connection.
  • On Windows: a webcam bridge app installed on both the iPhone and the PC, plus any driver the app requires. Follow that app's own instructions for setup and connection.
  • A way to hold the phone steady, such as a mount or stand. On a Mac, the phone should be locked, in landscape orientation and facing you with its rear cameras.

Step 1: Let OBS use the camera

On a Mac, open System Settings, go to Privacy & Security, then Camera, and make sure OBS is switched on. If you plan to use the iPhone microphone in OBS, do the same under Microphone. If you change these settings while OBS is open, quit and reopen OBS. On Windows, open Settings, go to Privacy & security, then Camera, and make sure camera access and desktop app access are allowed.

Success check: OBS is listed and enabled in the camera permission settings. This confirms only that OBS may request the camera. It does not show that the iPhone is connected or sending video.

Step 2: Connect the iPhone

On a Mac, position the phone near the computer, lock it and mount it in landscape. Continuity Camera does not need a separate app on the phone. On Windows, open the bridge app on the iPhone and on the PC, then connect them the way the app describes.

Success check: the bridge app reports a connection, or, on a Mac, the iPhone appears as a camera choice in OBS in the next step. If it doesn't appear, see the troubleshooting section below.

Step 3: Add the iPhone as a source in OBS

  • In OBS, select the scene you want to use in the Scenes panel.
  • In the Sources panel, click the plus button and choose Video Capture Device.
  • Name the source, for example "iPhone camera", and click OK.
  • In the Device menu, choose your iPhone. With Continuity Camera it usually appears under the phone's name. With a bridge app, it appears under the name that app gives its virtual camera.
  • Click OK, then drag and resize the source in the preview so it fills the frame the way you want.

Success check: the OBS preview shows a moving live image from the iPhone. On a Mac, the phone's screen typically shows that it is being used as a camera. This step confirms that OBS is actually receiving video, which is a separate thing from having permission (Step 1). It still says nothing about how the image will look in a call.

Step 4 (optional): Add the iPhone microphone

With Continuity Camera, the iPhone can also show up as a microphone on the Mac. To use it, add an Audio Input Capture source in OBS and pick the iPhone. Some bridge apps offer audio too, and others don't. Check the app's documentation.

Success check: the source's meter in OBS's Audio Mixer moves when you speak. A moving meter proves only that sound is reaching OBS. It does not prove the sound is clear. Record a short clip and play it back to hear whether your voice is intelligible and free of echo, clipping or noise. This guide has no verified input-level target to recommend. Use the meter to avoid peaking at the top of the scale, and judge the rest by listening.

Step 5: Send the OBS picture to a video call

  • In OBS's Controls panel, click Start Virtual Camera.
  • Open your call app or browser call and go to its video or camera settings.
  • Choose OBS Virtual Camera as the camera. In a browser, also allow camera access for that site when prompted.
  • If you added the iPhone microphone in OBS, note that the virtual camera carries video only. Choose your microphone directly in the call app.

Success check: the call app's self-view shows your OBS scene. This proves the call app is receiving the video. Picture quality, lag and stability on the other person's end depend on their connection and the call service too, so a short test call with someone else is the only way to check what they actually see.

If the iPhone doesn't appear or the preview is black

  • Re-check camera permission for OBS, then fully quit and reopen OBS.
  • Close other apps that might be using the camera, such as FaceTime or a call app, because one may hold the device.
  • On a Mac, confirm the iPhone is locked, in landscape, close to the computer and signed in to the same Apple Account, with Wi-Fi and Bluetooth on. Make sure Continuity Camera hasn't been turned off on the iPhone under its AirPlay and Continuity settings. Connecting with a USB cable can also help.
  • In the Video Capture Device properties, reselect the iPhone from the Device menu, or delete the source and add it again.
  • On Windows, restart the bridge app on both devices and confirm its driver or virtual camera is installed as the app describes.
  • If the call app doesn't list OBS Virtual Camera, start the virtual camera before opening the call app, or restart the call app after starting it.

Backgrounds and effects

What appears behind you can come from three different places. A physical background is the real room the iPhone sees. Virtual effects, such as background blur or replacement, can be applied by the Mac's video effects, by OBS filters, or by the call app, and stacking them can cause odd edges or wasted processing. If you use an effect, turn it on in only one place. An edited photo background, made after the fact in a photo editor, is a separate thing and doesn't apply to live video.

What this guide can't confirm

No verified evidence was available for exact iPhone models, macOS or iOS version requirements, specific bridge apps and their features or prices, resolution and frame-rate limits, latency, or recommended audio levels. Check Apple's current Continuity Camera requirements and the documentation for any bridge app you choose before relying on those details.
