D-cam
d-cam is a type of digital speed camera produced by the British subsidiary of the South African company Truvelo Manufacturers (Pty) Ltd. Testing by Transport for London commenced on the A4 Great West Road in London, in April 2007. The camera does not flash and can be used rear or forward-facing. It was the first combined traffic light camera and speed camera to be used in the United Kingdom. The new style of camera housing was designed by Bristol-based firm Crown (UK) Ltd. The equipment gained UK Home Office type approval early in 2014 and newly installed units started appearing shortly afterwards.

Gatso
Gatso is the brand that Gatsometer BV (now known as Sensys Gatso Group when Sensys acquired Gatso in 2015) 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. Operation Gatso installations in the UK and in Queensland, Australia are characterised by a measurement strip on the road surface ...

Truvelo Combi
Truvelo Combi is a speed camera manufactured by the South African company Truvelo Manufacturers (Pty) Ltd. It was approved in 1999. Background The Truvelo camera is usually a front-facing camera (it can also be rear-facing) taking pictures using a flash gun fitted with a magenta filter (the driver is less likely to be dazzled by the flash light). The reflected light provides the film with the correct exposure resulting in a clear picture of the driver committing the offence (considered as incriminating evidence). Piezo-electric road strips, a known distance apart (1.53 cm from 1 - 3, 2 - 4) are set into the road in front of the camera, and the time between compressions is measured using an impededance converter and two clocks in the camera to give the resulting speed of the vehicle. The system takes a single photograph (front-facing only, two for rear photography) and uses the time from the clocks to calculate the resulting speed. The photograph of the offending vehicle wi ...

Speed Camera
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used. The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum ''c'' = metres per second (approx ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

A4 Road (Great Britain)
The A4 is a major road in England from Central London to Avonmouth via Heathrow Airport, Reading, Bath and Bristol. It is historically known as the Bath Road with newer sections including the Great West Road and Portway. The road was once the main route from London to Bath, Bristol and the west of England and formed, after the A40, the second main western artery from London. Although most traffic is carried by the M4 motorway today, the A4 still acts as the main route from Bristol to London for non-motorway traffic. History Turnpikes The A4 has gone through many transformations through the ages from pre-Roman routes, Roman roads (such as the one passing Silbury Hill), and basic wagon tracks. During the Middle Ages, most byways and tracks served to connect villages with their nearest market town. A survey of Savernake Forest near Hungerford in 1228 mentions "The King's Street" running between the town and Marlborough. This street corresponded roughly with the route of ...

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Crown (UK) Ltd
A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (that is, ''The Crown''). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government''.
