+    \section1 Symbian Platform Security Requirements
+
+    On Symbian, processes which use this class must have the
+    \c UserEnvironment platform security capability.  If the client
+    process lacks this capability, calls to either overload of start()
+    will fail.
+    This failure is indicated by the QAudioInput object setting
+    its error() value to \l{QAudio::OpenError} and then emitting a
+    \l{stateChanged()}{stateChanged}(\l{QAudio::StoppedState}) signal.
+
+    Platform security capabilities are added via the
+    \l{qmake-variable-reference.html#target-capability}{TARGET.CAPABILITY}
+    qmake variable.
