Turn your phone into a working webcam in minutes

Your phone's camera is already better than most built-in laptop cameras. To use it as a webcam, you need an app that bridges your phone to your computer — the phone sends video through that app, and your computer sees it as a camera. The process takes about five minutes: read an app on both devices, connect them to the same network, and select your phone as the camera in whatever program you're using for calls or streaming.

The connection works over WiFi or USB cable, depending on the app. WiFi is simpler if your phone and computer are on the same network. USB is more stable for long calls or streaming, though it ties your phone to your desk. Most apps are free, though some charge for features like higher resolution or removing watermarks.

Key Takeaways

  • read a webcam app on your phone and the matching desktop software on your computer, then connect them over WiFi or USB.
  • Popular free options include Droidcam, EpocCam, and Iriun, each with slightly different features and connection methods.
  • After the app connects, open your video call or streaming software and select your phone camera from the camera list instead of your built-in webcam.
  • USB connections are more stable for long calls; WiFi is simpler to set up but may drop if your network is crowded.
  • Test the connection in a video call app before relying on it for important meetings.

Droidcam: the most straightforward option for Android

Droidcam works on Android phones and Windows or Mac computers. read the Droidcam app on your phone from Google Play, then read the desktop software from the Droidcam website onto your computer. Open both apps, and they will show you a connection code. Enter that code in the desktop app, and your phone camera appears as a selectable camera in Zoom, Teams, OBS, or any other program that uses your computer's camera.

The free version works over WiFi and includes basic video quality. The paid version ($4.99 one-time) adds USB connection, higher resolution, and removes the watermark. If you use your phone as a webcam regularly, the USB option is worth the cost because it won't drop if someone else joins your home WiFi network.

Droidcam also has a built-in microphone option, so you can use your phone's audio instead of your computer's microphone. This is useful if your phone has better sound quality or if you want to move around during a call.

EpocCam: works with iPhone and Android

EpocCam is one of the few apps that works with both iPhone and Android phones. read the app on your phone, then read the desktop software on Windows or Mac. The setup is similar to Droidcam: open both apps, let them find each other on your network, and your phone camera shows up in your video software.

The free version connects over WiFi only. The paid version ($7.99 one-time) adds USB connection and removes the watermark. EpocCam tends to have slightly lower latency than some competitors, meaning less delay between what your phone's camera sees and what appears on your computer screen — this matters if you're moving around or gesturing during a call.

One limitation: EpocCam's desktop software is less intuitive than Droidcam's. The connection sometimes requires you to manually refresh or restart the app if it loses the signal, whereas Droidcam usually reconnects automatically.

Iriun: lightweight and fast for both platforms

Iriun works on iPhone, Android, Windows, and Mac. It's known for being lightweight — it uses less battery and network bandwidth than some alternatives. read the Iriun app on your phone and the desktop software on your computer, open both, and they connect automatically if they're on the same WiFi network.

The free version includes WiFi connection and standard video quality. The paid version ($9.99 per year) adds USB connection, 4K video, and removes ads. Iriun's yearly pricing is cheaper than one-time purchases if you plan to use it for more than a year or two.

Iriun also includes a virtual camera feature on some systems, which means your phone camera can be selected as a default camera across multiple apps at once, rather than having to choose it individually in each program.

Connecting over USB versus WiFi

WiFi connection is the default for most apps and requires no cables. Both your phone and computer must be on the same network. The setup is faster, and you can move your phone around the room. The downside is that WiFi can drop if your network is congested, and video quality may suffer on slower networks. For casual video calls, WiFi is usually fine.

USB connection is more stable because the data travels directly through the cable instead of over your network. It's the better choice for streaming, long meetings, or situations where your WiFi is shared with many other devices. The trade-off is that your phone stays plugged into your computer, and you need a cable that supports data transfer (not just charging). USB also drains your phone's battery faster, though most phones charge while plugged in.

If you're using WiFi and the connection keeps dropping, switch to USB. If USB isn't an option, move your phone and computer closer to your router, or ask others on your network to pause large downloads during your call.

Selecting your phone camera in video call software

After your phone and desktop app are connected, open the video call or streaming software you plan to use — Zoom, Google Meet, Microsoft Teams, OBS, or another program. Look for the camera settings, usually found in a menu labeled Settings, Preferences, or Video. In that menu, you'll see a dropdown list of available cameras. Your phone camera will appear in that list with the app's name, like "Droidcam" or "Iriun Camera".

Click or tap to select it. Your phone's video should appear in the preview window. If it doesn't show up, close the video software completely, make sure the desktop app is still running, and reopen the video software. Some programs cache the camera list and need to be restarted to see a new camera.

Test the connection before an important meeting. Start a test call or record a short video to make sure the image is clear, the audio is working if you're using your phone's microphone, and the connection stays stable for at least a few minutes.

Troubleshooting common connection problems

If your phone and desktop app don't connect, check that both devices are on the same WiFi network. Some networks, especially public WiFi or networks with guest isolation enabled, prevent devices from seeing each other. If you're on a network like that, switch to a personal hotspot from your phone to your computer, or use USB connection instead.

If the video appears but is very laggy or freezes, your WiFi signal is probably weak. Move closer to your router, or switch to USB. If you're using USB and it still lags, try a different USB cable — some cables are data-only and work better than charging cables.

If the camera shows up in the video software but appears black or blank, the desktop app may not have permission to access your phone's camera. Check your phone's app permissions and make sure the webcam app has camera access. On Android, go to Settings > Apps > [app name] > Permissions > Camera. On iPhone, go to Settings > Privacy > Camera and make sure the app is toggled on.

If the connection works but your video is very dark, try adjusting the lighting in your room or moving your phone to face a light source. Phone cameras adjust automatically to light, so a darker room will produce a darker image. You can also check if the app has brightness or exposure settings.

When to use your phone instead of a built-in webcam

Your phone camera is usually sharper and has better color accuracy than a laptop's built-in camera, especially if your laptop is older. Phone cameras also have wider lenses, so you can fit more of your background in the frame without moving the device. If you're streaming, teaching, or doing video work where image quality matters, your phone is the better choice.

Your phone is also useful if your computer's built-in camera is broken or missing. Some desktop monitors and external webcams cost $50 to $150, while using your phone costs nothing extra if you already own it.

The main drawback is that your phone is tied up during the call — you can't use it for messages, notes, or other tasks while it's acting as a camera. If you need your phone free, a dedicated webcam or your computer's built-in camera is more practical.

Frequently Asked Questions

Can I use my phone as a webcam without WiFi?

Yes, if you use a USB cable and the app supports it. Droidcam, EpocCam, and Iriun all offer USB connection in their paid versions. Plug your phone into your computer with a data-capable USB cable, open both apps, and they'll connect directly without needing WiFi or a network.

Will using my phone as a webcam drain the battery?

Yes, especially over WiFi. The camera, screen, and WiFi radio all draw power. Over USB, your phone usually charges while plugged in, so battery drain is less of a concern. If you're using WiFi, expect to lose 10 to 20 percent of your battery per hour of use.

Can I use my phone's microphone while it's acting as a webcam?

Yes. Most apps let you toggle the phone's microphone on or off in their settings. This is useful if your phone has better audio quality than your computer, or if you want to move around during a call. Check the app's audio settings to enable it.

Do I need to pay for an app, or are the free versions enough?

The free versions work for most video calls. You only need to pay if you want USB connection, higher video quality, or no watermark. For casual Zoom or Teams calls, the free version of Droidcam, EpocCam, or Iriun is sufficient.

What if my phone camera is better than my computer's, but I still want to use my computer's microphone?

Use the phone camera but disable the phone's microphone in the app settings. Your computer's microphone will stay active, and you'll get the video quality of your phone with the audio from your computer.
