Just thought I'd clarify that the colours above are as a result of the camera having not yet switched from Infrared mode, back to True-colour mode. There is a transitional period during dusk/dawn, where the camera still has the IR filter in place, as it's still in IR mode due to low light levels. Once it detects enough light, it will switch to daylight mode and the colours will look normal once again.
3 of my 6 cams are Infrared capable, the above Lochgelly camera being one, but also the Aberdour and St. Andrews SkyCam as well. http://www.fifeweather.co.uk/index.php/weathercam
