<title>Example: Positions of a window on sensor</title>
22962296
<para>A window with VGA resolution (640x480) that is natively mapped to the same number of pixels of a cropped area on a 3MP (2048x1536) sensor, would have the pan and tilt range of:</para>

<para>As long as the aspect ratio of the window and the sensor are identical, the same ranges for pan and tilt are expected. The device will automatically adjust the ranges based on the amount of source pixels represented in the window of interest (its width and height configured in the VideoSourceConfiguration of the requested profile).</para>
