Noel O’Donoghue Q&A: ‘I’ll advise them to look upon HawkEye as a friend’

HawkEye’s Point Detection System is a camera based system that assists officials when awarding points scored between the posts, via an audio signal relayed to the referee within seconds of the sliotar crossing the line.
Hawk-Eye provides real-time imagery on the stadium’s big screen of a ball’s trajectory over the posts to remove any ambiguity over whether a point was scored or missed.
