CourtCam

One ceiling camera per gym court: pickleball replays, basketball make/miss, cornhole scoring and coaching clips

Does the jobs of CourtCall, SmartHoop, CornholeCam and CoachVision with one brain: a ceiling head over each court plays the last 30 s on the court TV at the press of a wall button, counts makes and shot spots, scores cornhole rounds and cuts every coaching rep for the player who tapped in.

Who buys it: Facility or recreation manager of a rec centre, YMCA, sportsplex or school gym with 1 to 6 courts booked by the hour.
Why it pays: $1,790 per court + $69/month instead of $8,575 + $257/month for our CourtCall, SmartHoop (2 hoops), CornholeCam (hub + 2 lanes) and CoachVision bought separately; one Pi 5 + Hailo-8 replaces four hubs (est.).
Target price: $1,790 per court (head, CourtKey, 2 RimPods, 20 wristbands) + $69/court/month (target)
First-minute wow: The same court shows a pickleball replay at 6 pm, a shot chart at 7 pm and a live cornhole score at 8 pm, with nothing moved and nobody filming.

What the research found

And how this design answers it

Four hubs (CourtCall, SmartHoop, CornholeCam, CoachVision each had a Pi 5 + Hailo-8) → one Pi 5 + AI HAT+ in each ceiling head
Eight-plus cameras on fences, arms, lane heads and bay posts → two Camera Module 3 Wide in one head: one down at the court, one at the hoop
CourtCall's replay button and CoachVision's bay tap reader → one CourtKey on the wall with REPLAY and TAP
SmartHoop's RimCam arm over the rim → dropped; the RimPod is kept for rim contact
Mode follows the booking (pickleball, basketball, cornhole, coaching), so one court earns from every block in the gym schedule

Use case

Tuesday at a rec centre gym

Front deskPlayersCoachLeague host

01Trigger: the booking system sets court 2 to pickleball at 6 pm, basketball at 7 pm and cornhole league at 8 pm
02Detection: the head films from above; a player presses REPLAY and the rally plays on the court TV
03Count: at 7 pm a member taps a wristband and shoots; the head counts makes, the RimPod catches rim hits
04Action: at 8 pm the same camera scores each cornhole round on the TV; coaching reps reach the coach's tablet

Outcome: One device per court sells replay, shooting, league scoring and coaching clips; $6,785 less hardware than four products (est.)

How it works

Architecture

01
Sense: two Camera Module 3 Wide (court and hoop), RimPod accelerometer, CourtKey button and tap reader
02
Decide: Pi 5 + Hailo-8 runs the detector for the booked mode, ACL scoring, make/miss and rep cutting
03
Send: Ethernet over PoE+ to the venue network; BLE from the RimPods; Wi-Fi from the CourtKey
04
Tell: court TV page, CourtCam app for desk, coaches and players, clip links by QR

Hardware

Real parts, buyable today

Bill of materials: about $560 per court at qty 10, plus one PoE+ switch per gym (est.).

Block	Part	Why this part
Brain	Raspberry Pi 5 8GB + AI HAT+ 26 TOPS (Hailo-8) in the head	Runs player, ball and bag detection on two streams; the brain all four sources already used
Cameras	2 x Raspberry Pi Camera Module 3 Wide (102°)	One looks down at the whole court, one at the hoop
Power	PoE+ splitter to USB-C 5 V 5 A, TP-Link TL-SG1210P switch	One cable per head for power and network
CourtKey	XIAO ESP32-C6, 30 mm LED arcade button, PN532 NFC, 18650	Replay and tap-in on the wall, no cable
RimPod	XIAO ESP32-C3 + LIS3DH, 500 mAh	Rim contact so close shots count right

Open risks we are working on

One head straight down at 7.6 m covers about 19 x 10 m (est.): one pickleball court or two cornhole lanes; a full basketball court needs two heads
Make/miss from 9-12 m at 30 fps is untested; the RimPod backs it up
Fitting at height needs the venue's contractor, a lift and a safety cable
Video of juniors: no face recognition, clips leave only on request, recording only while booked
No line calls or official decisions; scores are shown with a replay to check
