Before your first game
Follow the setup guide and try one short replay. FanEye does not make automatic line calls; players and officials review the footage and decide.
Replay is a reference, not an automatic verdict.
FanEye does not automatically detect the shuttle landing or decide IN or OUT. Players or officials review the footage. Device, lighting and network conditions matter.
