Eons ago, Disney used to have web cams in the parks. This was back when the idea of the webcams was pretty new and "cutting edge". They were located on the Main Street train station, above American Adventure and above the Studios turnstiles.
I know there were a few in Animal Kingdom, because the park had recently opened and was the focus on the WDW website. There were feeds from the cameras on the safari/Pangani trail that you can see when you're up at Conservation Station.
All of these cams have been gone for a very long time. (Rumors say it was due to 9/11, but I think they were on their way out before then)
There also was/is a Weather Bug camera on the Dolphin facing Epcot. (It was put to good use back when the Wand was being dismantled and we were keeping a daily watch on its progress)
