Gatso is a brand of speed measurement equipment, speed cameras, red-light cameras and road-access control/enforcement equipment of various types manufactured by the Dutch company GATSOmeter BV. The company's history started with a device invented by champion rally driver Maurice Gatsonides. He used the device to record his speeds as he drove through various curves and other road configurations, so that he could review his line and speed so as to optimise his performance in future races. The company was later formed to market the devices as police speed enforcement tools and remains largely a family concern with two Gatsonides among the five directors.
The company's products, particularly the "Gatsometer 24", have achieved such a high level of market penetration in certain European countries that the term "Gatso" has become synonymous with "speed camera" across a significant proportion of Europe. Historically, the company has had less success marketing its products in the USA . . . However, Gatsometer BV now has an American subsidiary, in the form of GATSO-USA, which now markets the company's products direct and competes with the other speed/red-light camera companies active in the North American market. . .
Speed cameras often become victims of vandalism from disapproving motorists who see them as government money making schemes. Vandalism includes ramming with vehicles, or more commonly burning with petrol filled rubber tyres. There have been dozens of documented cases of speed cameras being disabled across the UK. -- Wikipedia
