Images whose contents are not known [1] 

The "Images whose contents are not known" section of the HTML5 spec contains
the following regarding Webcams. 

In some unfortunate cases, there might be no alternative text available at all,
either because the image is obtained in some automated fashion without any
associated alternative text (e.g. a Webcam), or because the page is being
generated by a script using user-provided images where the user did not provide
suitable or usable alternative text (e.g. photograph sharing sites), or because
the author does not himself know what the images represent (e.g. a blind
photographer sharing an image on his blog).

In such cases, the alt attribute's value may be omitted, but one of the
following conditions must be met as well:

* The title attribute is present and has a non-empty value.
* The img element is in a figure element that contains a figcaption element
that contains content other than inter-element whitespace.
* The img element is part of the only paragraph directly in its section, and is
the only img element without an alt attribute in its section, and its section
has an associated heading."


There would always be something a person could provide for a Webcam text

Please provide an example that is in line with WCAG 2 or defer to "HTML5:
Techniques for providing useful text alternatives":
http://dev.w3.org/html5/alt-techniques/ as it is anticipated that a Webcam
example will be added there. http://www.w3.org/Bugs/Public/show_bug.cgi?id=9174
