To use your phone as a webcam for OBS, you connect your smartphone's camera to OBS Studio on a desktop computer, turning your phone into a high-quality video source for streaming or recording. This works over USB or Wi-Fi, and OBS itself does not run on the phone, the phone acts as a camera source for the desktop OBS install.
What you need to use your phone as a webcam for OBS
You need a smartphone with a functional camera, a computer with OBS Studio installed, and either a USB cable or a Wi-Fi connection depending on the method you choose. Both iPhone and Android phones work with desktop OBS, and a stable network connection helps ensure smooth video transmission.
Method 1: OBS iOS Camera plugin (iPhone, USB)
This official OBS plugin workflow gives you a reliable, low-latency connection using a Lightning cable. The OBS iOS Camera plugin docs say to install the app on the iPhone, add an iOS Camera source in OBS, then connect the device with the Lightning cable that came with it. The OBS iOS Camera plugin page says USB is selected by default in the app’s output settings. If the connection does not happen automatically, the plugin docs say to tap the refresh devices button and choose the device from the list.
Method 2: Third-party apps for iPhone and Android
Apps like EpocCam, iVCam, or DroidCam stream your phone camera feed to OBS over Wi-Fi or USB. General setup steps across these apps include installing the app on your phone and the companion software on your computer, ensuring both devices are on the same network, then selecting the app as a video source in OBS. For Android users, some apps also support a USB tethering option for a more stable connection.
Method 3: IP Webcam for Android (Wi-Fi)
For a wireless Android connection, set up the IP Webcam app on your phone. Open the app, configure the video settings, and note the stream URL displayed on the screen. In OBS, add a new Media Source, enter that URL, and the phone’s camera feed will appear in your scene.
Using Apple Continuity Camera with OBS (Mac only)
Continuity Camera lets you use your iPhone as a webcam on a Mac, and you can select it as a source in OBS. Requirements include an iPhone XR or later, a Mac, the same Apple Account with two-factor authentication, Bluetooth and Wi-Fi enabled, and Continuity Camera enabled on the iPhone (check in Settings > General > AirPlay & Continuity or AirPlay & Handoff). For iPhone on Mac, the normal OBS source path is Sources > + > Video Capture Device, then select the iPhone camera device if Continuity Camera is available. Apple says you can use one iPhone and one Mac at a time with Continuity Camera. Continuity Camera works wirelessly, but not while the Mac is using AirPlay or Sidecar; Apple says Continuity Camera over USB requires the iPhone to trust the Mac.
Connecting your phone and adjusting OBS settings
Once you’ve chosen a method, add the phone as a source in OBS by clicking the + button under Sources and selecting the appropriate source type (iOS Camera, Video Capture Device, or Media Source). Position and resize the feed in your scene so it appears correctly. For basic quality adjustments, ensure good lighting, position the phone at a suitable distance and angle, and check focus and exposure within the app. Higher resolutions and frame rates may improve quality but require a stable connection.
Troubleshooting phone webcam issues in OBS
If the phone does not appear as a source, try refreshing devices in the app or OBS, and confirm USB trust settings on the iPhone. For video lag or audio sync problems, check your Wi-Fi signal strength, close unnecessary background apps, and consider using a USB connection for lower latency. If the app crashes, reinstall or update it. For Continuity Camera, verify that both devices are on the same Apple Account, Bluetooth and Wi-Fi are on, and the iPhone is nearby. If Continuity Camera is not appearing, Apple says to confirm Settings > General > AirPlay & Continuity or AirPlay & Handoff. If you need to screen mirror Android for a different purpose, that’s a separate feature, this workflow is specifically for using the camera as a webcam source.
Frequently Asked Questions
Can I use my phone's microphone as the audio source in OBS?
Yes, most phone webcam apps let OBS capture audio from the phone’s microphone. In OBS, add an Audio Input Capture source and select the app or device name. For better quality, consider using a separate microphone.
Will using my phone as a webcam drain the battery quickly?
Yes, streaming video uses significant power. Keep your phone plugged into a charger via USB while using it as a webcam, especially during long streams or recordings.
Does the phone need to stay unlocked while streaming to OBS?
In most cases, yes, the app must remain open and the screen on for the video feed to continue. Some apps offer a “keep awake” setting to prevent the screen from dimming.
Can I use both the front and rear cameras on my phone?
Most phone webcam apps allow you to switch between the front and rear cameras within the app’s settings before or during streaming. Check the app’s interface for a camera toggle button.
What if my phone is not detected by OBS over USB?
Ensure you have installed the correct drivers or plugin for your method. For iPhone, tap “Trust This Computer” when prompted. For Android, enable USB debugging in Developer Options and select “PTP” or “MTP” mode if required by the app.
