+        As a general rule, when the {camid} references the camera_id in the main motion.conf file, the webcontrol
+        actions referenced above are going to be applied to every camera that is connected to Motion.  This camera_id
+        is usually specified as 0 (zero).  So issuing a command of <code>{IP}:{port}/0/detection/pause</code> is
+        going to pause all the cameras.
+        <p></p>
+        A point of clarification with respect to the differences between <code>pause</code>, <code>quit</code>,
+        and <code>end</code>.  When the action of <code>pause</code> is executed, Motion will stop the motion detection
+        processing and of course all events but will continue to process and decode images from the camera.  This allows
+        for a faster transition when the user executes a <code>start</code>  The <code>quit</code> action conversely not
+        only stops the motion detection but also disconnects from the camera and decoding of images.  To start motion
+        detection after a <code>quit</code>, the user must execute a <code>restart</code> which will reinitialize the
+        connection to the camera.  And since the camera was completely disconnect, it can take more than a few seconds
+        for Motion to fully start and have the camera available for processing or viewing.  Finally, there is an
+        option for <code>end</code>.  This option completely terminates the Motion application.  It closes all connections
+        to all the cameras and terminates the application.  This may be required when running Motion in daemon mode.
+        Note that there is no way to restart the Motion application from the webcontrol interface after processing
+        a <code>end</code> request.
