Turn your phone into a webcam with free or paid apps

You can use your phone as a webcam by installing an app that connects it to your computer over Wi-Fi or USB. The phone becomes a camera input that your computer recognizes, so video call software like Zoom, Google Meet, or Teams can use it instead of your built-in webcam. Most setups take five to ten minutes and work on both Android and iPhone.

The main advantage is that phone cameras are often sharper and have better low-light performance than laptop webcams. You also get more flexibility with positioning — you can mount your phone on a stand, hold it at an angle, or place it farther away than a built-in camera allows.

Key Takeaways

  • Apps like Iriun, DroidCam, and EpocCam let your phone act as a webcam by connecting over Wi-Fi or USB cable.
  • Your computer needs the companion software installed on both the phone and the desktop to recognize the phone as a camera.
  • Wi-Fi connection is simpler to set up but uses more battery; USB is more stable and charges your phone while in use.
  • Once connected, your video call software sees the phone camera as a regular webcam input and works without extra steps.
  • Free versions of most apps include basic webcam function, while paid versions add features like background blur or screen mirroring.

Iriun: the most straightforward option for most users

Iriun works on both iPhone and Android and is free for basic webcam use. read the Iriun app on your phone, then read the Iriun software on your Windows or Mac computer. Open both, and your phone appears as a camera option in any video call software within seconds.

The free version includes the core webcam function. The paid version ($9.99 one-time or $4.99 per year) adds features like background blur, portrait mode, and the ability to use your phone's rear camera instead of the front. Most people do not need the paid version for standard video calls.

Iriun works over Wi-Fi by default, which means your phone and computer must be on the same network. Battery drain is moderate — expect to lose 10 to 15 percent per hour of video call. If your phone gets warm, switch to USB connection in the app settings.

DroidCam: the budget option with USB stability

DroidCam is free on Android and costs $4.99 on iPhone. It offers both Wi-Fi and USB connection modes. The USB option is more stable for long calls and charges your phone while in use, making it the better choice if you do video calls regularly.

read DroidCam on your phone and the DroidCam client on your computer. If you use USB, plug your phone in with a standard charging cable, open both apps, and tap connect. The phone shows up in your video call software within a few seconds. Wi-Fi mode works the same way but requires both devices on the same network.

DroidCam's free version includes the basic webcam function and audio from your phone's microphone. The paid version adds features like custom resolution and the ability to use the rear camera. For most users, the free version is sufficient.

EpocCam: the option for iPhone users who want simplicity

EpocCam is designed for iPhone and iPad and costs $7.99 one-time. It works over Wi-Fi or USB and has a clean interface that requires fewer settings to adjust than other options.

Install EpocCam on your iPhone and the EpocCam software on your Mac or Windows computer. Open both, and your phone appears as a camera input. The app automatically detects your computer on the same Wi-Fi network, so there is no manual IP address entry or pairing code needed.

EpocCam includes background blur and portrait mode in the paid version. If you prefer a one-time purchase over a subscription, this is the most straightforward iPhone option, though it costs more upfront than Iriun.

Wi-Fi versus USB: which connection method to use

Wi-Fi connection is wireless and requires no cable. Both your phone and computer must be on the same network. Setup is faster, and you have more freedom to move around. The downside is battery drain — your phone uses power to maintain the connection and stream video. Wi-Fi also depends on your network strength; if your signal is weak, video may lag or drop.

USB connection is more stable and charges your phone while in use. Your phone stays plugged into your computer with a standard charging cable. Video is smoother because the connection is direct, and there is no network dependency. The trade-off is that you are tethered to your desk and cannot move the phone without unplugging.

For occasional video calls, Wi-Fi is fine. For daily use or long meetings, USB is worth the cable. Most apps let you switch between the two in settings, so you can try both and see which works better for your setup.

How to set up your phone camera in Zoom, Teams, or Google Meet

Once your phone is connected via your chosen app, your video call software needs to know to use it. Open Zoom, Teams, Google Meet, or whichever platform you use. Look for settings or preferences, then find the camera or video input option.

In Zoom, click Settings, then Video, and select your phone from the Camera dropdown. In Google Meet, click your profile picture, then Settings, then Camera, and choose your phone. In Teams, go to Settings, then Devices, then Camera, and select your phone from the list. The exact steps vary slightly by platform, but the principle is the same: your phone appears as a regular camera option once the connection app is running.

Test the video before your call. Open the camera preview in your video call software to confirm the image is clear and the angle is right. Adjust your phone's position or lighting if needed. Once you close the video call software, you can disconnect the phone app — it does not need to stay running in the background.

Troubleshooting common problems

If your phone does not appear in the camera list, make sure both the phone app and the computer software are open and running. Restart both if they have been open for a while. If you are using Wi-Fi, confirm that your phone and computer are on the same network — check your phone's Wi-Fi settings and your computer's network settings to verify.

If the video is laggy or keeps freezing, switch from Wi-Fi to USB if possible. If you are already on USB, try unplugging and plugging back in. Close other apps on your phone that might be using bandwidth, like email or social media. On your computer, close browser tabs and other programs that consume network resources.

If the image is dark or blurry, check your phone's camera lens for dirt or fingerprints and wipe it clean. Move your phone closer to a light source or adjust the angle to avoid backlighting. Some apps have brightness or focus settings in their menu — try adjusting those if the image quality does not improve.

If your phone gets very hot during use, switch to USB connection, which is more efficient. Close other apps running on your phone. If the problem persists, take a break and let the phone cool down before resuming.

Frequently Asked Questions

Can I use my phone as a webcam without installing anything on my computer?

No. All phone-to-webcam apps require software on both your phone and your computer to create the connection. You cannot use a phone camera through a web browser or without downloading a companion program on your desktop.

Will using my phone as a webcam drain the battery quickly?

Wi-Fi connection drains battery noticeably — expect 10 to 15 percent per hour. USB connection charges your phone while in use, so battery is not a concern. If battery life matters for your use case, USB is the better choice.

Can I use the rear camera on my phone instead of the front camera?

Most apps allow this, but it is usually a paid feature. Iriun, DroidCam, and EpocCam all offer rear camera access in their paid versions. The rear camera is sharper on most phones, so it can improve video quality if you have the paid version.

Do I need a fast internet connection for Wi-Fi to work?

No. Phone-to-webcam apps use very little bandwidth — a standard home Wi-Fi network is more than enough. The connection is local between your phone and computer, not routed through the internet, so your internet speed does not matter. Network stability matters more than speed.

What happens if I close the phone app while I am on a video call?

Your video call software will lose the camera input and show a black screen or an error message. You will need to close and restart the call, or quickly reopen the phone app and reconnect. Keep the phone app running in the background for the duration of your call.
