Change of Camera

The web cam which had been used since the server has been set up, displayed some visual artefacts in areas of high contrast. I have now replaced this camera with another one which does not seem to have this problem. Unfortunately, the image quality is more blurry than the precious camera, and the lens has a smaller aperture angle, which means that a smaller segment is shown. But it seems to have a backlight compensation, which may be useful in the evenings when the camera points in the direction of the sun.
