Can I get help with setup and operation if needed?
Yes. Baseline is designed for easy self-operation. We do offer a personalized onboarding call along with ongoing support from our team.
Can I Baseline for singles and doubles?
Yes, doubles is fully supported. The ultra-wide camera covers the entire court, while continuous ball-trajectory tracking keeps accurate tabs on play, even when players cross paths.
What happens if a ball hits the camera?
Our cameras are shockproof and made to withstand intense match play. Just in case, we also cover ball damage under our warranty.
How accurate is Baseline’s line calling?
Under good court and lighting conditions, Baseline Vision is over twice as accurate as the human eye (up to 95% accuracy). For tournament level accuracy , we recommend our dual-camera setup.
Does Baseline offer automated electronic line calling?
Baseline adapts to your officiating format so you can choose between Live Electronic Line Calling (ELC) or Review Mode for chair umpire verification.
Does Baseline work on all surfaces?
Yes, Baseline Vision works on all surfaces. However, loose clay can sometimes cover court lines. While reduced line visibility may impact line-calling accuracy, general performance tracking and statistics remain unaffected.
