+        <para>The Relative Zoom Translation Space in FOV is introduced to simplify magnification with dome cameras in graphical user interfaces. When the user wants to modify the magnification of the current camera view, they draw an area centered in the middle of the current FOV, which defines the zoom factor.</para>
+        <para>The zoom factor is represented by the ratio between the width of the desired area (Ww) and the width of the display window used for the video stream (Sw) relative to the current field of view.</para>
