Welcome to the forum
@gand22 and your first post. I note that no poster has said that they wanted cameras on the Camino. They wanted to know which webcams are working and other posters provided links. Webcams are there fullstop.
What use do they have? Obviously, to control our every step ...
That was a joke of course. Some webcams are PR gimmicks, some webcams serve to report and illustrate current motor traffic flow, some to report and illustrate current weather conditions. Did you look at any of the webcams in the links or do you shun them? I sometimes look at the image provided by the webcams inside the Santiago Cathedral, recently even to follow the Pilgrim Mass as there is now not only image but also sound. Wonderful solo voice sometimes - the Agnus Dei and the rousing Hymn to the Apostle are a joy to listen to. The view over the lake near Logroño and the surrounding landscape or from O Cebreiro bring back pleasant memories. Sometimes there is snow! Simple pleasures.
