iirc, there's a certain query that's similar to this one which you could type into Google and control various security cameras around the world which are all on the WAN. Not only can you view the picture being recorded by the cameras, but you could rotate the cameras right from the web interface too.<p>I (un)fortunately can't remember the certain query needed, but it's not too hard to find it — I'm sure it's been mentioned on various news articles or YouTube videos. If I remember, it relied on the cameras all sharing the same filename for the PHP page to access the interface.
