+       <p>
+        Camcorder is a non-visible component that records a video using the device's camera.
+                After the video is recorded, the path to the file on the phone containing the
+                video is available as an argument to the AfterRecording event. The path can be
+                used, for example, as the source of an VideoPlayer component.
