This is the current view from the loft of the Ono Wingerei house. It automatically refreshes every minute. The camera is situated indoors behind a window and sometimes the sunscreens are down and the camera image has "black bars" all over. If you have a RTSP aware player (for example VLC) you can open the url rtsp://weathercam.trollaasen.info/high.sdp and watch a 10 fps live stream from the camera.
