Brand by Gatsometer BV From Wikipedia, the free encyclopedia
Gatso is the brand that Gatsometer BV (now known as Sensys Gatso Group when Sensys acquired Gatso in 2015[1]) use on their speed cameras and red light cameras. The most commonly encountered Gatso speed cameras emit radar beams to measure the speed of a passing vehicle. If it is travelling above the preset trigger speed, one or two photographs are taken (depending on the device's setting, which generally depends on the requirements of the local jurisdiction). These use a powerful flash, to show the rear of the vehicle, its registration plate, and calibration lines on the road (in many jurisdictions). Newer installations used digital cameras which have limited exposure latitude compared to film, these installations use an auxiliary flash placed close to the position where a speeding vehicle would exit the radar beam and the first photograph would be taken.

Gatso installations in the UK and in Queensland, Australia are characterised by a measurement strip on the road surface, which is a series of white lines painted on the road, which are used with two photographs taken by the camera. These white lines are sometimes known as 'secondary check marks'. The camera is set to take two photographs, with a constant time interval between them, usually 0.5 seconds for faster roads and 0.7 seconds for slower roads. The difference in the vehicle's position in the two photographs can be used to calculate its speed.
In the UK, the evidence is admissible in court using the speed measured by the radar. The speed calculated from the distance travelled between the photographs using the secondary check mark white lines is used by police forces to verify the radar reading, and can be used as a defence in the event of an unreliable reading by the radar.
It can be a common misconception by drivers that the police do not use the distance travelled between the secondary check marks before issuing a notice in the post. The police can make mistakes, but the combination of radar reading and secondary check marks is a robust case for prosecution.
The speed indicated by the radar unit can be prone to error due to multiple reflections etc. With a minority of vehicle types such as lorries towing a curtain sided trailer. Further, it does not distinguish between multiple vehicles in shot, however secondary check marks will identify which vehicles are speeding, providing the police with corroborative evidence.
The first red light cameras were introduced in an initiative in the City of Nottingham in 1988 following a triple fatal road traffic accident at a traffic light controlled road junction.[citation needed]
The Department of Transport took an interest, and sponsored a trial involving the Home Office and the Metropolitan Police. The operational base was at the West London Traffic Unit. Roger Reynolds, a Police Sergeant (later to become President of the Royal Photographic Society) undertook operational trials of the equipment and, by adjusting the camera controls, managed to use colour film for the first time replacing black and white film. Reynolds made the first successful use of the Gatso camera on the A316 road at Twickenham Bridge in 1992.[2]
The first controlled junction was at the Hanger Lane Gyratory, on the A406 North Circular Road southbound at its junction with the A40 Western Avenue. This junction was then followed by the A501 Marylebone Road at its junction with Gloucester Place. A further installation was commissioned on the eastbound A40 at its junction with Long Lane (Hillingdon). After the camera units were deployed there was a significant reduction in accident rates in their vicinity.[citation needed]
The Police Camera team developed paper handling systems using (then) current process and later laid down systems to incorporate conditional offer fixed penalty systems. The processes developed by the team formed the basis of similar systems, used and modified by other police forces. Also a member of the Team travelled to Hong Kong and assisted in the introduction of cameras there.[citation needed]
Speed cameras were also evaluated by the Metropolitan police team for their speed limit enforcement capabilities before the system was rolled out. The linear markings suggested by the team are now an integral part of the camera site marking.[citation needed]
The team that introduced the system and the engineers of the Department of Transport, as road safety specialists, were keen to use the equipment to change driver behaviour and thus improve road safety. However strategic control of cameras later moved to the safety camera partnerships. prosecution thresholds. Many UK police forces apply the enforcement threshold guidelines recommended by the National Police Chiefs' Council.
Gatso cameras in the UK previously had deployment requirements, in common with all fixed speed camera types operated in the UK by safety camera partnerships (SCPs) under the National Safety Camera Programme (NSCP). They had to be marked, made visible, located in places with a history of serious accidents, and where there was evidence of a speeding problem, or where there was a local community concern.[3]
Since April 2007 however, such requirements have been removed. It is still recommended that cameras be made visible and roads with fixed ones, clearly signed, but they can now be placed at any location, regardless of its crash history. Cameras operated solely by the Police, outside the NSCP schemes, do not need to comply with visibility requirements.[4]
The funding arrangements for SCPs also changed in April 2007. SCPs no longer keep the funds from speeding fines. After this, an annual 'road safety grant' was given to local authorities, who can choose whether or not to invest it in these partnerships. The Specific Road Safety Grant was cancelled in 2010 by the Department for Transport following the 2010 UK Government's Comprehensive Spending Review. As of 2020 there is no annual funding for road safety from the UK Government to Local or Combined Authorities.
Concerns have been raised that the powerful flash used when the cameras trigger may dazzle drivers travelling in the opposite direction. The flash on the Truvelo Combi is fitted with a magenta gel to obviate this issue.
The Gatso camera is manufactured by the Dutch company GATSOmeter BV. The company's history started with a device invented by the champion rally driver Maurice Gatsonides.[5] 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 the UK and some European countries that the term "Gatso" became synonymous with "speed camera" across a significant proportion of Europe.[citation needed] Historically, the company has had less success marketing its products in the USA, where it operated initially through agents or by selling its cameras to other companies that would integrate them into larger systems for customers. The most notable installed base of Gatsometer products in the USA is that in and around Washington, D.C. 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.
