+        The model name must to the extent possible describe the sensor. For most
+        devices this is the model name of the sensor. While for some devices the
+        sensor model is unavailable as the sensor or the entire camera is part
+        of a larger unit and exposed as a black-box to the system. In such cases
+        the model name of the smallest component closest to the sensor must be
+        used.
+
+        The model name is not meant to be a camera name displayed to the
+        end-user, but may be combined with other camera information to create a
+        camera name.
+
+        The model name is not guaranteed to be unique in the system nor is
+        it guaranteed to be stable or have any other properties required to make
+        it a good candidate to be used as a permanent identifier of a camera.
+
+        The model name shall describe the camera in a human readable format and
+        shall be encoded in ASCII.
+
+        Example model names are 'ov5670', 'imx219' or 'Logitech Webcam C930e'.
