<p>The "URL provided" link points at the contact:* page, so
presumably whoever wrote that was assuming that the live image
URLs should be tagged under the contact namespace. I agree that
it's bizarre tagging practice, but I understand how it happened,
since that's where almost all URLs more specific than "url" or
"website" have found a home, and many of those are predominately
used to publish info rather than to receive communication.<br>
</p>
<p>Taginfo doesn't break down the common tag combinations for
surveillance:type=camera, but here's my attempted tally using
overpass:<br>
website 1485<br>
contact:webcam 1146<br>
url 204<br>
contact:website 115<br>
url:webcam 29<br>
webcam 17</p>
<p>Note that there's some overlap as some cameras have more than one
of these tags (sometimes with different values.) And there may be
some variations that I missed. <br>
</p>
<p>Simple website=* is the most popular, but often it points to
things other than a camera feed, most commonly the site of the
person or institution that runs the camera. Often it holds the URL
of a top-level view of many cameras while contact:webcam holds the
direct URL to the camera in question.<br>
</p>
<p>My favorite of these is url:webcam. But contact:webcam is
hundreds of times more popular.<br>
</p>
<p>What's wrong with just url=*? To quote the url=* wiki page, "<i>it
is advised not to use this tag when more specific alternatives
are available.</i>" Like website=*, it doesn't specify that it's
a camera feed, so it might be used for other purposes. And in fact
I happened to see a couple of nodes using url=* for picture *of*
the camera, rather than pictures taken by the camera.</p>
