A total of 23 cameras will capture the performance from multiple angles, including cameras installed on rooftops more than 1.6 kilometers away. Specialized equipment includes the aerial “EagleEye” system, the “Towercam XL” reaching heights of up to 10 meters, remote-controlled moving cameras and Steadicams. The total volume of recorded footage is expected to reach 108 terabytes, supported by 40 terabytes of server capacity.
