If you want to stream live video but don't have a webcam, or your webcam is very old, DroidCam OBS is a great app to have on hand. With it, you can transform your smartphone into a webcam in just a few seconds. All you have to do is connect it to your PC via USB or WiFi, after which you can start streaming video with the front and rear cameras on your Android.
To use DroidCam OBS, you'll need to install OBS Studio on Windows, since that's the program your device will link to. Once you have the program installed on your PC and the app installed on your phone, simply select the camera you want to use and start streaming. (You can switch between your front and rear cameras whenever you want by tapping on the option you prefer.)
One of the advantages of using DroidCam OBS is the ability to link various devices to the same account and stream from any one of them, several at once, or switch between them as needed. With this app, you'll have your own recording station to stream and record anything you want.
You can also use this app with your smartphone screen turned off and your device connected to your PC via USB, which avoids draining the battery so you can record longer videos without a problem. Record high-quality audio or video without a webcam. After all, who needs a webcam when you have an Android smartphone?
