Whether the 14 cameras that monitor the goals of Brazil fifa 14 coins had been the 2014 July 30, 1966 in Wembley, England might not have a world championship title.

The World Cup that begins Thursday will be the first in history without "ghost goal" as that final or most recent English Frank Lampard in South Africa 2010.

"Of the 400 incidents 2000 tested at different stages, all were recognized correctly. We are 100% sure that the system works, "he said Monday in Rio de Janeiro Johannes Holzmüller, FIFA responsible for the implementation of a proven and successful technology in the Confederations Cup and the Club World Cup in Morocco last year.

A total of 14 cameras at the top of the stadium to seven each goal-oriented monitor whether or not the ball crosses the goal line and inform the clock's in less than a second if it was a goal or not.

Cameras and software triangulate the position of the ball and determine if it is within the goal or not.

When the ball between the referee and his three assistants receive a visual and vibrating on his watch. Goal, will read.

The Auto Detector Goals (DAG) will be in the 12 World Cup venues at a cost that FIFA refused today to reveal for confidentiality contract with GoalControl, the contest winner.

For the viewing angle and the limitation of the human eye, FIFA ensures that only a genius like DAG can be 100% sure.

Cameras process more than 500 images per second, the eye 16. "We want protection for referees," he said today Holzmüller.

"We are more interested in the impact of an incident that the number of incidents," he said, knowing that a single action can have far-reaching significance.

FIFA wants to finish at least one of the usual sources of controversy. Therefore, a situation such as the famous goal by Geoff Hurst at Wembley in 1966, which helped England win the world title in the final against Germany, nor as clear therefore not granted Lampard also front will not be repeated German group in South Africa 2010.

"If there is anything positive about what happened in South Africa, would be the introduction of technology," Lampard said last week.

Germany beat England 4-1 in the second round of the South African World Cup, but after 38 minutes and 2-1 in favor of the German team, the referee awarded a goal from Lampard which, as seen in the following repetition, clearly surpassed the goal line.

"This is not a solution, but is the solution," says convinced the president of FIFA, Joseph Blatter, who after years of suspicion was convinced to introduce technology as old as little inclined to change its core game.

"Football keeps its human face. It was clear to us that South Africa could not be repeated, "said Blatter.

What happened in Bloemfontein with the goal of Lampard not four years ago triggered the process. After numerous tests, discard the chip in the ball and in July 2012 received the approval of the International Board, guarantor of the rules of football, now the technology is ready.

"It's really a great help," said Massimo Busacca, director of FIFA referees.

The DAG is infallible, boasts FIFA. And even withstand an attack from hackers: when a system offline , there will be risks that hackers can manipulate the signal, as said Dirk Broichhausen, CEO of GoalControl.
