Home security cameras use HomePlug™ technology

Devices that use the mains power supply to transfer data / video can cause severe intereference to the reception of broadcast radio stations in nearby houses.

It seems that new Home Security Cameras are now adding to the problem.

Logitech have recently launched their new Home Security Video Cameras in the British Isles and Europe.
These devices send the video from the cameras to the PC by transmitting a broadband High Frequency radio signal into the mains supply.

Page 22 of the December 2007 issue of Personal Computer World (PCW) magazine mentioned the problems of similar devices that transmit data/video over the mains, the article said:

"Mains wiring acts as an aerial when passing radio-frequency data signals and, as we have reported before there are fears about the cummulative effect in cities if the technology gets taken up on the same scale as WiFi."
