Goal-line technology is being used at the 2014 World Cup. The first goal confirmed by the system was in the game between France and Honduras.
The GoalControl system uses 14 high-speed cameras (seven for each goal). These cameras film at 500 frames per second. Images from the cameras are processed to a margin of error of five millimetres, and within one second the referee receives a signal as to whether a goal has been scored.
In the France vs Honduras game, the system gave two decisions. The first decision was that Karim Benzema’s shot that bounced off the post was not a goal. The second decision confirmed that all of the ball did cross the line when the goalkeeper Noel Valladares tried to save the rebound from the post.
The goal was recorded as an own goal rather than credited to Benzema.
