The Swiss company called Multanova AG has a camera and radar combi that can be used in a vehicle or tripod. It uses K band radar 24.100 GHz.
Finnish police and ROBOT Visual Systems GmbH has an agreement of delivering a total of 16 mobile MultaRadar C units, installed in the Finish police’s vehicles.
About their units You can find here http://www.multanova.ch/zulassungen_en.php
We found one of the first units, in a Ford Tourneo Connect mini van.
Car was parked beside the main road number 25 in southern Finland
Here´s a video with Finnish explanation (don't care about it ;c) - just listen to STi)
(download) ( as long as our bandwith stays up)
STi gives 12 seconds warning time at 75 kph speed - some 250 metres.
