Search Google for "how to film a tennis match" and you'll find every kind of advice — gimbals, drones, multi-camera rigs, $400 4K action cameras. There's a Talk Tennis thread literally titled "What equipment do I need to film my tennis matches?" where the same question gets the same scattered answer.

Here's the answer. You need: your phone, a $15–$25 fence-mount clip, and the ten minutes it takes to read this post. Total spend: under $30 (depending on the clip).

This is everything. The rest is upsell.

TL;DR — the gear list

Item	Cost	Where	Why
Your phone	$0 (you have one)	–	Any phone made in the last 5 years works
Fence-mount phone clip	$15–$25	Amazon, eBay, AliExpress	Holds the phone on a chain-link fence at the right height
Optional: silicone band	$3	Wherever	Belt-and-braces in case the clip slips
Optional: portable battery	$20	Wherever	If you film 90+ minute matches and your phone dies

Total: $15–$48 depending on which optionals you add.

If you do not have a chain-link fence — backboard wall, bubble court, public park with no fence — skip to the tripod section below. If you do, the fence clip is the right answer.

What "analysis-grade" video actually requires

Before we talk gear, here's what an AceSense (or any tennis AI) pipeline actually needs from your video:

Both baselines visible in frame. The full court should be visible from the back of one baseline to the back of the other.
Roughly centred horizontally. The phone shouldn't be off to one side of the court — it confuses court keypoint detection.
30 fps minimum, 60 fps better. Higher frame rates give finer time resolution for speed estimation. Most modern phones default to 30 or 60.
1080p minimum. Higher resolution helps the ball detector. 4K is not necessary; 1080p is the floor.
Stable. Hand-holding is bad. Anything that doesn't sway is fine — a fence clip, a tripod, a railing.

That's the whole spec. Notice what's not on the list: zoom (you don't want it — wide is better), follow-tracking (you don't want it — fixed view is better), 4K (not necessary), an action camera (overkill).

Why a fence clip is the right default

Most outdoor and indoor club courts have a chain-link fence behind the baseline. A fence clip — a moulded plastic or aluminium gripper with a phone holder on it — clips onto the fence at the height you want, holds your phone, and stays put for as long as you need. It's the simplest, cheapest, fastest setup that exists.

The Quora question "Good camera to use that I could just hook to a fence?" gets at the same intuition. The right answer is: don't buy a camera, use the phone you already have, and buy a $15 fence clip.

What to look for in a fence clip:

Adjustable jaw to fit different chain-link gauges (most clubs have similar gauges; AliExpress generic clips fit fine).
Tilt adjustment so you can point the phone slightly down at the court, not straight forward.
Quarter-inch tripod thread or phone-cradle directly built in. The phone-cradle versions are simpler — no tripod adapter needed.
Rubberised contact points on the fence-grip side so it doesn't slide.

We don't endorse a specific brand because the AliExpress generics are roughly equivalent to the branded ones at a third of the price. Search "tennis fence phone mount" or "GoPro fence clamp" — both will surface the right product type.

What to avoid:

Anything magnetic-only. Magnets to your phone case, sure; magnets to the fence, no. The phone needs to be held by the fence, not floating off it.
Cheap suction-cup mounts. They don't grip chain-link fence reliably.
Anything that requires a tool to install. You should be able to clip, position, and unclip in 30 seconds.

Where to put the camera

The single most important decision in your $30 setup. We have a dedicated post on camera angle and height, but here's the short version:

Behind the baseline you're recording from (yours or the opponent's — pick one and stick with it across sessions for consistent comparison).

Centred — on the centreline of the court, not off to one side.

Net-tape height to a foot above — about 3 to 4 feet (1m to 1.2m). Higher than this and you compress the perspective; lower and the court back doesn't show.

8 to 12 feet behind the baseline — far enough that the full court fits in the wide-angle phone view.

Slight downward tilt — maybe 5–10 degrees, just enough to put the back of the opposite baseline in frame. The tilt adjustment on your fence clip is what does this.

If your court has no fence at the right position — say it has a 12-foot fence at 20 feet behind the baseline, instead of a 6-foot fence at 8 feet — clip higher on the further fence rather than closer at the wrong height. Distance is more forgiving than height.

What if no fence?

About 15% of the courts our users film on don't have a usable fence — public-park courts in Mediterranean climates, indoor bubble courts, retractable-court setups. In those cases:

Option 1: Tripod. A 4-to-5-foot extending tripod with a phone clip. Cost: $25–$40 for one that's stable. Place behind the baseline at the same position. The downside is wind — outdoor tripods on light tripods can sway, which adds noise to the video. Sandbag the legs if it's windy.

Option 2: Existing fixture. Net-post mount (some sell), an umpire chair if there's one, a bench at the back of the court. The principle is "anything that doesn't move."

Option 3: A friend. Worst option, only-if-nothing-else option. A handheld phone is the worst case for AceSense — every drift in the holder's stance is a court-keypoint drift in the video. If a friend must hold it, they should sit behind the centreline with the phone on a knee-prop, not handheld at chest height.

We have a separate post coming on the no-fence court mounting alternatives for the edge cases.

Specifically what we do not recommend

The internet will sell you on a lot of things. Most of them aren't worth it for analysis purposes:

Auto-tracking AI cameras (Pivo, OBSBOT, etc.). These follow the player around. Bad for AI analysis. Auto-tracking introduces panning that breaks court keypoint detection — every time the camera moves, the court coordinates have to be re-estimated, and the homography drifts. The Quora "footage that followed the tennis player" question reflects a misunderstanding — for AI analysis, you specifically don't want a moving camera. A fixed camera with the whole court in frame is what the algorithm needs.
Drones. Cool. Useless for analysis. Wind makes them unstable; the angle is wrong; the FAA / EU airspace rules are onerous. Skip.
Multi-camera rigs. Unnecessary. AceSense is monocular; one phone is the input. A second camera doesn't help.
Wide-angle lens attachments. Most modern phones already shoot at a wide-enough angle. The clip-on wide-angle adapters introduce edge distortion that hurts court keypoint detection.
Gimbal stabilisers. For run-and-gun video, fine. For tennis, you want a fixed camera, and a gimbal is overkill for that use case.

A few things are worth more money if you're going to spend any:

A modern phone. If your phone is more than 5 years old and shoots only 30 fps, an upgrade has real impact. But that's a phone upgrade, not a tennis-recording purchase.
A second-hand iPhone for tennis-only use. An iPhone 12 used at €200 with 60 fps recording, dedicated to tennis filming, is a setup we've seen work for serious club players. Belongs in your tennis bag.

Setup checklist for the day

When you arrive at the court:

Clip the phone mount to the fence behind your baseline, centred.
Adjust height to net-tape level or slightly above. Tilt slightly down.
Open the camera app, switch to video, set to 1080p / 60fps if available.
Tap the screen to focus on the court (not on the fence).
Hit record.
Walk to the court. Play.

After the match:

Stop recording.
Upload via AceSense (or whatever app).

The whole pre-match setup takes 90 seconds once you've done it twice.

What this saves you

The default upsell on tennis-recording gear is $300+ of stuff you don't need. Putting an entry-level phone, a $15 clip, and the right placement against a $300 setup with the wrong placement: the cheaper one wins on AI analysis quality. Placement is more important than gear.

So spend the $300 you saved on lessons, hitting partner sessions, or the AceSense subscription. They'll improve your tennis more.

Next: The right camera angle and height for AI shot detection is the deeper dive on placement. How to record your serve for analysis is the same setup adapted for solo serve practice. Or jump to /how-it-works to see what the analysis pipeline does with the video you've just filmed.
