More than 6000 sneak preview were recorded during the seven months that the newspaper reporter had a webcam installed in his living room.
On one occasion an unknown person hacked into the camera from an IP address in Italy and secretly looked at the reporter, who at the time was in his living room.

In Sweden, there are at least 31,000 web cameras connected to the internet according to DN's survey.
