There have been some neat Google tricks popping up lately (first seen on boingboing) to find web/security cams on the web. Some web cams that haven’t been secured have a specific syntax in their URL that Google has indexed and are searchable. Here are a few Google searches for cams:
SecurityFocus News has a short article about this recent find.
I got lost yesterday for about a half hour digging through these cams. They are pretty interesting to look through (even a little scary). Several people have put together collections of cameras online. Opentopia has a search that allows you to sort the cameras by country. Jesse from Bug Heaven put together a Python script to pull camera images from the search results. There is also this page from Undertree.us that is just a huge list of links to different cams.
Have fun… don’t get too lost in other places via the cams!
