Web camera installed at Mull of Galloway lighthouse on 1st April 2005. This camera has been funded by the European Region Development Fund. This is an innovative project involving a web camera, a radio link and satellite broadband access to the world wide web.
Proper streaming too, I hadn't expected to see the camera pan, tilt and zoom as I selected from the presets.
