Helmet Camera
A helmet camera, otherwise known as a micro video camera, is an action camera, usually a closed circuit television camera, attached to a helmet allowing someone to make a visual record from their point of view ( POV), while keeping their hands and vision free. History Archives containing photos of helmet cameras have surfaced over the last decade. One shows Denver Broncos backup quarterback Jacky Lee wearing a helmet camera at football practice in 1965. A mocked-up helmet camera appears in the opening scenes of '' The Private Afternoons of Pamela Mann,'' released in 1974, used by a character for voyeurism. Another early and more noble helmet video camera was a 1977 head-mounted camera designed to convert images into tactile sensations for the blind. Almost a decade later, a Canon CI-10 camera was mounted to the side of Dick Garcia's helmet by Aerial Video Systems (AVS) of Burbank, CA at the Nissan USGP 500 World Championship at Carlsbad Raceway in Carlsbad, CA on June 28, 198 ...

Body Camera
A body camera, bodycam, body worn video (BWV), body-worn camera, or wearable camera is a wearable audio, video, or photographic recording system. Body cameras have a range of uses and designs, of which the best-known use is as a part of policing equipment. Other uses include action cameras for social and recreational (including cycling), within the world of commerce, in healthcare and medical use, in military use, journalism, citizen sousveillance and covert surveillance. Research on the impact of body-worn cameras in law enforcement shows mixed evidence as to the impact of cameras on the use of force by law enforcement and communities' trust in police. Designs Body-worn cameras are often designed to be worn in one of three locations: on the torso, on or built into a helmet, and on or built into glasses. Some feature live streaming capabilities, such as GPS positioning, automatic offload to cloud storage, while others are based on local storage. Some body-worn cam ...

Ice Hockey Refcam
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Hockey
Field hockey is a team sport structured in standard hockey format, in which each team plays with ten outfield players and a goalkeeper. Teams must drive a round hockey ball by hitting it with a hockey stick towards the rival team's shooting circle and then into the goal. The match is won by the team that scores the most goals. Matches are played on grass, watered turf, artificial turf, synthetic field, or indoor boarded surface. The stick is made of wood, carbon fibre, fibreglass, or a combination of carbon fibre and fibreglass in different quantities. The stick has two sides; one rounded and one flat; only the flat face of the stick is allowed to progress the ball. During play, goalkeepers are the only players allowed to touch the ball with any part of their body. A player's hand is considered part of the stick if holding the stick. If the ball is "played" with the rounded part of the stick (i.e. deliberately stopped or hit), it will result in a penalty (accidental touc ...

Cameras By Type
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outside Broadcasting
Outside broadcasting (OB) is the electronic field production (EFP) of television or radio programmes (typically to cover television news and sports television events) from a mobile remote broadcast television studio. Professional video camera and microphone signals come into the production truck for processing, recording and possibly transmission. Some outside broadcasts use a mobile production control room (PCR) inside a production truck. History Outside radio broadcasts have been taking place since the early 1920s and television ones since the late 1920s. The first large-scale outside broadcast was the televising of the Coronation of George VI and Elizabeth in May 1937, done by the BBC's first Outside Broadcast truck, MCR 1 (short for Mobile Control Room). After the Second World War, the first notable outside broadcast was of the 1948 Summer Olympics. The Coronation of Elizabeth II followed in 1953, with 21 cameras being used to cover the event. In December 1963 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Hockey
Ice hockey (or simply hockey) is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. In ice hockey, two opposing teams use ice hockey sticks to control, advance and shoot a closed, vulcanized, rubber disc called a " puck" into the other team's goal. Each goal is worth one point. The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport. Ice hockey is one of the sports featured in the Winter Olympics while its premiere international amateur competition, the IIHF World Championships, are governed by the International Ice Hockey Federation (IIHF) for both men's and women's competitions. Ice hockey is also played as a professional sport. In North America as well as many European countries, the sport is kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Football
American football (referred to simply as football in the United States and Canada), also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins. American football evolved in the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
