Stumbled upon this, and been having tons of fun with it. If you google the code under this, the results will seem a load of gibberish. They are, in fact, password-free network cams, most of which allow you to control them. Panning, zoom, etc. I have found ones from places like the UK, scattered all the way to Japan. I personally feel like big brother, watching over the world. It's also rather odd to think that because of me clicking, somewhere in the world a little camera is physically moving around.

There are literally hundreds to try out. (some of which are locked, meaning only that they can't be moved, only looked through.) The majority are not locked, that I have tried.

Simply Google this term.

NOTE - Google is the best search engine for this that I have tested. Other search engines seem to give you unrelated results for this particular term.
