Proprio nel pomeriggio sentivo parlare di telesorveglianza e sicurezza… poi capito qua e leggo:

These webcams were found automatically through a variety of clever search techniques. Their owners might or might not have intended for them to be public. But they obviously are. Many of them are security cameras in companies or semi-public places. If you hover over the picture you’ll see what location information is available. If you click on it, a window will open and you can see a live video feed, plus comments and ratings and other information.
1398 webcams are available as of last scan.
