The Brazilian government acquired 27 robots from US company IRobot for $7.2m which are able to detect bombs and explosives, as well as other risk activities in and around the venues. The equipment, which has been used to detect explosives in Afghanistan and Iraq, will also be deployed in the Olympic Games in 2016.
All World Cup venues are also equipped with a vast amount of surveillance cameras - for example, the Arena Fonte Nova in Bahia has 227 cameras that capture images in high definition, scattered across all sectors of the venues, including strategic areas inside and outside the stadia. The cameras can recognize and store data of up to 400 faces per second.
2. Goal line technology
Goal line technology will be in place for the first time at a World Cup to support match officials. Some 14 high-speed cameras, seven per goal, will be in place at each of the 12 World Cup stadiums to determine if an attempt on goal has crossed the line or not.
The cameras provided by German firm GoalControl then send data to a central image processing computer system that tracks the ball’s position to determine whether it has crossed the line or not. When the goal is confirmed, a signal is sent to the referee’s watches.
