QG sells an on-court camera, server, and tablet system that calls balls in or out and records detailed match data.

Landing page captured for the 2026-09-14 issue.

Field notes

QG describes a venue-contained setup built from perimeter cameras, an on-site server, and a tablet-based umpire console. Its model reconstructs the bounce and compares the mark with the line edge, while the training view records speed, spin, depth, net clearance, shot maps, and rally video. The page distinguishes a club-and-academy Smart Court from a competition-level ELC system and also advertises tournament rental with an on-site operator.
