It offers a free edition so that you don’t have to pay for the feature. In addition, this application allows you to control your iPhone camera using its desktop client. In this way, you can easily zoom in/out, mirror, and adjust color and brightness.

Actually, FineCam is beyond this, now download it and go to explore. (compatible with iOS 13 and above, even iOS 16.)

  1. Download and install FineCam on your iPhone from App Store and your PC via the official website.
  2. Remember to allow it all the required permissions to make it operable.
  3. Connect them via a USB cable. If you wish for a wireless connection, make sure both devices are connected to the same Wi-Fi network.
  4. Run FineCam on both devices and send a connection request from any one of them. From the iPhone, you only need to follow the on-screen commands. But if you wish to send through your PC, click on Camera > Connect an iPhone.
  5. After accepting the request on the other device, the last step is turning on the Virtual Camera. It is located in the bottom middle of your PC FineCam. Now you can use your iPhone as a webcam on any streaming platform.

Besides turning iPhone into a webcam, FineCam also makes it simple to remove, blur and change the background, add multiple scenes, use filters and effects, and more.

How to Use Android Phone as Webcam for PC via USB

To connect your phone to your PC, you will require software that can act as a bridge. Fortunately, we have a recommendation for you, namely DroidCam. It is fantastic software that instructs your computer to recognize your phone’s camera as a webcam.

You can have astonishing video quality without any lag by connecting via USB. The software works for phones above Android 5.0 (Lollipop). On PC, it works well with Windows 10 and Linux. However, you won’t get any support for Mac OS. Here’s how to use it via USB without Wi-Fi:

  1. Download and install DroidCam on both your PC and your phone.
  2. Now you need to enable the Developer Options on your phone. For this purpose, go to your mobile’s Settings > About Phone.
  3. Tap on Build Number up to 7 times.
  4. Once enabled, go back and find this new functionality in the settings.
  5. In the Developer Options, scroll to USB Debugging and toggle the switch on. The step is compulsory.
  6. Connect your phone and PC through a USB cable, and launch DroidCam on both.
  7. Click on the USB sign in the middle of your PC and click Start. Your PC will auto-detect your Android and start the video right away.

But what if you want to connect your phone with the Mac? Again, the third-party complications also apply here. But some webcam software has made the task easy. You can use Reincubate Camo, specially designed to work with iOS devices like Mac and iPads.

Is USB Connection Better Than Wi-Fi Connection?

Every method has its perks and downfalls. As connecting through Wi-Fi gives you the flexibility of moving, you are not limited to the length of your cable. However, the USB connection works even better in terms of quality and latency. You can have a crispy clear video with latency almost equal to zero.

Are These Methods Free For Turning A Phone Into a Webcam?

Of course! All the above methods are free, legit, and easy to use. You don’t need to spend any to get them. However, they also offer better resolutions and additional benefits in their premium version. You can always spend a little to get an extra mile of advantages (despite the FineCam, which is completely free with all the beneficial features).

The Bottom Line

Converting your phone into a webcam is not a difficult task. All you need is appropriate software. USB connections are the best option for zero latency and vivid video quality. We’ve told you how to use your Andriod and iPhone as a webcam for your PC without Wi-Fi. Choose the best method for yourself and start recording.
