What technology is used to review a decision?

The third umpire may use, during a Player Review:

• replays at any speed from any available broadcast camera;
• stump microphone sound, with replays at normal speed and slow motion;
• approved ball-tracking: HawkEye (HawkEye Innovations) or VirtualEye (ARL);
• approved sound-based edge detection: Real-Time Snickometer (BBG Sports) or UltraEdge (HawkEye Innovations);
• approved heat-based edge detection: Hot Spot cameras (BBG Sports);
• LED wickets: Zing Bails and Stumps.

Other technology may be used if the ICC is satisfied it meets the required standards of accuracy and time efficiency. The ICC Match Referee makes the final decision on the technology used in a match, in consultation with the ICC Technical Official, ICC management and the teams' governing bodies.
