Tennis Blackbox records tennis play at highest available speed up to 240 fps.
When players disagree on the last line call, they can stop video recording for the review.
Last 2 minute full HD video at the slow motion is stored for review.
If players do not agree on even with the slow video, Tennis Blackbox analyzes the video and provides its own line call decision with the decision video.
With Tennis Blackbox, tennis players do not need to shout on the call. Just see the video for correcting the call and focus on the play.
