Camera guide

The perfect setup, in four steps.

Half the battle when filming is where the camera goes. Here you see, with real examples, where your device needs to go so the whole court is in frame and the AI cleanly detects every point.

You'll find this guide in the app too, right before you record.

How to set up the camera.

Centered behind the baseline.

Place the camera centered behind the baseline, a little back from it, aimed straight at the middle of the court.

The app's camera guide for placing the device

2.5 to 4 meters high.

Slightly above net height and tilted down toward the middle of the court, for example on a fence mount. With a regular tripod at 1.5 m the cut works just as well, only the ball marks get less precise.

Set up too low: the top edge of the net hides the far baseline, it can't be seen.
Bad
Still a bit too low: the far half of the court is hard to make out.
Okay
Good height: the far baseline sits above the top edge of the net and is clearly visible. Only the service line on the opposite side is still just below it.
Good
Perfect height: the entire court is clear and free of overlaps.
Perfect

The whole court in frame.

Zoom so the court fits with all lines and a little margin, not too close and not too far.

Zoomed in too close: the near baseline and the near corners of the singles and doubles court are cut off.
Bad
Still too close: the singles lines are fully visible, enough for singles. But the doubles lines are cut off on the near side.
Okay
Zoomed out a little too far: too much unused margin is left to the left and right of the court.
Good
Perfect zoom: the whole court fills the frame with a little margin, all lines are visible.

Frequently asked questions

Yes. The automatic cut into rallies works just as reliably from that height. Only the ball marks get less precise, because the near player hides the ball more often. For full accuracy, hang your device on the fence at 2.5 m with a fence mount.

Easiest with a camera mount that hooks into the fence behind the baseline. Alternatively the stands, a terrace or a tall tripod behind the fence.

Yes, the setup is the same. When zooming, make sure the doubles lines are fully in frame on both sides, and pick Doubles in the app.

No. Detection is built for the view from behind the baseline, because only then are both players and all lines in frame at the same time.

Yes. In portrait the court does not fit in frame. You can still export your rallies in 9:16 for Reels and TikTok afterwards.
