Mac-Cam is a high-speed video camera used in tennis for instant replays of close-line calls.
It focuses on shots landing near the baseline. The camera was named after tennis legend John McEnroe. Mac-Cam helps officials and viewers see if a ball is in or out.
It captures fast-moving tennis balls clearly, showing their exact landing spot. Mac-Cam was an early form of tennis replay technology. It paved the way for more advanced systems like Hawk-Eye.
While no longer used, Mac-Cam was important in bringing technology to tennis officiating.
