Hawk-Eye Sensors Ltd | Court Coverage/Sensitivity

Court Coverage/Sensitivity

Hawk-Eye places the sensors where needed based on the situation. For those, who expect to use Hawk-Eye with or without umpires, we recommend our Hawk-Eye Comprehensive sensor pattern. For those who expect to always have at least one umpire officiate the match, we recommend our Hawk-Eye Supervised sensor pattern. Finally, for those using Hawk-Eye for charity / serving competitions, we have designed a temporary installation of sensors placed on top of the court, which we call “Serving Competition ”.
Comprehensive	The Comprehensive pattern consists of 7 circuits on each side of the court. The circuits provide definitive “in” and “out” coverage around each of the boundary lines. Maximum coverage is provided at the base lines and at the service lines, traditionally the most difficult lines to call. For example, around the base line, the system definitively knows whether the ball was in or out for a minimum of 12 inches. Shots outside the 12 inch area are called by the players themselves or umpires.
Supervised	The Supervised pattern is a simpler design consisting of a total of 8 circuits for the full court. It places circuits only on the boundary lines, and assumes that Hawk-Eye is strictly an aid for those who officiate the match. For very close shots, it definitively indicates whether the ball was in and hit the edge of the line or was in by a couple of inches and skidded over the line.
Serving Competition	The Serving Competition pattern is a pattern that is expected to be used for charity type events, training facilities, and demonstrations of the Hawk-Eye Sensors capabilities. By placing 8 circuits around a single service box, the accuracy of the server can be determined with respect to how often the serve is catching the edge of the white line, in or out by an inch, all the way to in or out by over 6 inches.
