+# Webcams
+
+Webcams are video cameras which are designed to be used with a computer for
+streaming, video calls or similar usages.
+This section lists and explains software for the handling of webcams under a
+Linux operating system.
+
+## Editing Video Stream
+
+The editing of a video stream provided by a webcam can be achieved by using
+[OBS](/wiki/obs.md) together with the
+[OBS Virtual Camera plugin](/wiki/obs.md#virtual-camera).
+This works on [Windows](/wiki/windows.md) aswell as [Linux](/wiki/linux.md) and can be used for any
+webcam available.
+
+## Configure the Webcam
+
+On Linux a webcam can be configured with [guvcview](https://guvcview.sourceforge.net/).
+This program provides a simple interface for capturing and viewing video from a
+[v4l2](/wiki/linux/v4l2.md) device and is thus dependent on v4l2.
+Additionally guvcview provides an interface to configure various webcam settins
+and enable a few effects on top of it.
+
+## Using a Smartphone as Webcam
+
+A [smartphone](/wiki/smart_devices.md) and its camera aswell as flashlight can be used as a simple
+replacement for a webcam.
+For [Android](/wiki/android.md) smartphones this can be easily achieved by using
+[DroidCam](/wiki/android/droidcam.md).
+An alternative to DroidCam with a with decidedly better resolution is
+[IP Webcam](/wiki/android/ip_webcam.md).
