Technical requirements

Suggested device, browser, network, power and venue setups for reliable, low-friction use of Wushu Precision — broken down by role. These are recommendations, not enforced minimums: the platform will run on less, but reliability and operator comfort drop accordingly.

Last reviewed 2026-05-19
Tier 1

Viewer

Spectators, athletes and coaches reading public competition pages, results lookup, leaderboards and profile on their own device. The lightest profile — anything you'd use to read a news site works.

Device
Any modern phone, tablet, laptop or desktop from 2020 or later. Screen size doesn't matter — pages are responsive down to 360 px wide.
Browser
An evergreen build of Chrome, Safari, Firefox or Edge from the last two years. JavaScript and cookies must be enabled.
Network
Around 1 Mbps is plenty for results and leaderboard pages. Cellular, home WiFi or hotel WiFi are all fine.
Power & peripherals
Not applicable — whatever battery your device has is fine.
Venue / environment
Not applicable — viewable from anywhere with a connection.
Account / permissions
No sign-in required for public competition pages, leaderboards and results. A free account is needed only to register as an athlete, manage your profile, or follow specific events.
Tier 2

Live venue display

Wall-mounted TVs, projectors or kiosk monitors running scoreboards, leaderboards, the live schedule or finalised results in fullscreen for the audience and competitors. Unattended, always-on, no interaction. The platform anticipates this use — the scoreboard page keeps a separate colourway from the operator's laptop so a venue TV can run a high-contrast dark theme regardless of what the operator prefers.

Device
A 1080p or higher display driven by one of:
  • A smart TV with an evergreen browser app.
  • A mini-PC, NUC, Chromebox or media-player stick on HDMI.
  • A spare laptop on HDMI — functional, but pricier per screen and the lid must stay open.
Browser
Evergreen Chrome, Edge or Safari with fullscreen / kiosk mode. Use the OS screen wake-lock (or the browser's "presentation" equivalent) so the display doesn't sleep mid-event.
Network
Stable 2 Mbps+ is enough; wired Ethernet to the display device is strongly preferred over venue WiFi for an unattended screen. Pages are reconnect-tolerant — a brief network blip recovers without intervention.
Power & peripherals
Continuous mains power on a circuit you trust — no battery reliance. For long unattended sessions, consider HDMI-CEC for scheduled on/off, a wireless keyboard kept at the head table for the rare manual recover, and good cable strain relief.
Venue / environment
Mount at a viewing angle and height that covers the room, with brightness sized to the ambient light (projectors need a dimmer space than TVs). Avoid direct overhead glare. If multiple displays show different views (scoreboard, leaderboard, schedule), label them clearly.
Account / permissions
No sign-in needed — the public scoreboard, leaderboard and schedule URLs are open. The operator just opens the URL on the display device and enters fullscreen. For high-contrast venue viewing, switch the scoreboard colourway to onyx or ink from the scoreboard's own theme switcher.
Tier 3

Judge

Covers the full modern panel (Head Judge, QoM, OP, DD, Assistant Head Judge) and Traditional, Line, Quick, Guest and Custom judge interfaces. Head and advanced judges may also use the replay review tools — noted below where it raises requirements.

Device
Tablet (10"+) in landscape preferred, or a laptop. Phones work for Line and Quick judging in a pinch but the tap targets are designed for a larger touch surface. For Head Judge / QoM replay review, a tablet or laptop is strongly recommended.
Browser
Chrome 110+, Safari 16+, Firefox 110+ or Edge 110+. Replay playback works in all four — the replay player uses the device's native HLS on Safari / iOS and a bundled fallback everywhere else, so no extra plugin is needed.
Network
2 Mbps sustained per device, low latency. The judging core writes each tap directly to Firestore and corrects for each device's measured round-trip, but consistently flaky WiFi will surface as missed consensus windows. Wired or stable venue WiFi over a hotspot.
Power & peripherals
Charger plugged in for the full session — an 8-hour day drains all but the largest tablets. Optional: a stylus for Head Judge note-taking, a tablet stand to keep the screen upright on the panel desk.
Venue / environment
Stable seat at the judging panel with line-of-sight to the carpet. Avoid backlight glare on the tablet screen. Keep devices off the floor so cables aren't a trip hazard.
Account / permissions
A registered judge account, assigned to the relevant panel by the organiser ahead of the event. Guest and Quick Judge flows allow lighter-weight access; the organiser sets which.
Tier 4

Video capture

Camera-position operators running the capture page on a phone, uploading per-routine clips to the replay backend. The most demanding tier — sustained recording across a long day puts real thermal, battery and network load on the kit. Numbers below mirror the internal operations runbook.

Device
Per camera position (1–4 per carpet): one iPhone 12 or later, or a current-gen Android, with a recent Chrome or Safari. Mounted in landscape orientation — the capture page best-effort locks orientation, but the phone must physically be rotated landscape on the mount.
Browser
Recent Chrome (Android) or Safari (iOS). Camera and microphone permission must be granted on first pair. Firebase Auth sign-in is required before pairing.
Network
2 Mbps sustained uplink per camera is the minimum; per-routine uploads burst to 5–10 Mbps for the 10–30s window after each routine ends. A wired Ethernet hotspot beats venue WiFi every time. Keep an LTE/5G fallback (Peplink, tethered phone, etc.) as insurance.
Power & peripherals
  • Tripod with phone clamp, oriented landscape.
  • USB-C PD charger (≥ 30 W) plugged in before pairing. The capture page warns if the battery is below 80% and not charging.
  • Optional but strongly recommended: a small fan pointed at the phone, or the case removed, so heat dissipates. Continuous recording across an 8-hour session is genuinely demanding thermally.
Venue / environment
Clear sightline from the camera position to the carpet, away from foot traffic. Run a pair + record test for an hour before the comp opens and watch the upload HUD between mock routines.
Account / permissions
An approved organiser account on Firebase Auth. The chief referee / organiser prints the camera QR sheet from the competition setup; operators scan their assigned QR at each carpet to pair.
Tier 5

Organiser, official & admin

Running the event is several different jobs with very different device needs — the same person may do more than one, but the kit that suits each task is different. Four sub-roles below.

Gate & ticket scanning

5a · Smartphone-first
Device
A smartphone with a working rear camera and reliable autofocus. One device per gate / scan position. Phones beat tablets here — lighter, faster to point, easier to hold one-handed across an arrival rush.
Browser
Mobile Chrome (Android) or Safari (iOS), with camera permission granted to the ticket scanner page.
Network
Modest — each scan is a tiny round-trip to validate the ticket. Stable venue WiFi is best; cellular is a fine fallback. If you have multiple gates, give each its own phone rather than time-sharing one device.
Power & peripherals
Charger or pre-charged spare battery / power bank. A phone-on-lanyard or a small belt pouch keeps scanners hands-free between guests.
Venue / environment
A well-lit gate area — QR autofocus struggles in low light. Weather protection if scanning outdoors. Position the scanner so the screen isn't glare-blasted by the sun.
Account / permissions
An organiser account, or an event-official account that the organiser has invited to the competition.

Floor-walking officials

5b · Incidents, medals given, jury floor presence
Device
Tablet or smartphone, whichever is easier to carry around the floor for the day. These flows are light-touch and mostly text-entry — no special screen-size needs.
Browser
Evergreen mobile Chrome or Safari.
Network
Tolerant of intermittent connectivity — filing an incident report or marking a medal given is occasional, not continuous. Venue WiFi or cellular both work.
Power & peripherals
Portable battery pack helpful for an 8-hour day on the floor. A lanyard or wristlet so the device doesn't get put down somewhere awkward.
Venue / environment
Free to move around the floor with line-of-sight to all carpets the official is covering.
Account / permissions
Event-official or jury role assigned by the organiser ahead of the event.

Chief referee & head table

5c · Live competition control · in venue
Device
Laptop or desktop with a full keyboard. A 1440 px-wide display or larger makes multi-window work much easier (schedule, scoreboard, judge panel status side-by-side). A second screen at the head table earns its keep.
Browser
Evergreen Chrome, Firefox, Safari or Edge.
Network
Wired Ethernet strongly preferred, 5 Mbps+. The head table is the worst place to be on flaky WiFi. If only wireless is available, sit close to the access point and have a wired hotspot or tethered phone as backup.
Power & peripherals
A UPS or battery-backup at the head table is well worth it — venue mains glitches happen, and the head table going dark mid-event is more disruptive than anywhere else. Mouse and full-size keyboard if the laptop is small.
Venue / environment
Clear sightline to every carpet the head table is covering, ideally elevated. Position the screen to avoid the audience reading it over the chief referee's shoulder.
Account / permissions
Chief-referee or organiser role on the specific competition.

Event setup, schedule, billing & admin

5d · Desktop workflow · can be remote
Device
Desktop or laptop with a full keyboard. These flows (schedule edits, CSV upload, ticket pricing, billing, admin panels) involve a lot of typing and large tables; a phone is genuinely a bad fit.
Browser
Evergreen Chrome, Firefox, Safari or Edge.
Network
5 Mbps+ wired or stable WiFi is plenty. CSV uploads and asset uploads benefit from a faster connection but aren't time-critical.
Power & peripherals
Mains power for long sessions — building a competition schedule or running billing reconciliation comfortably eats a battery.
Venue / environment
No venue constraint — this work can be done remotely from the office. A quiet desk and a real chair beat doing it on the venue floor.
Account / permissions
Organiser-admin role on the competition. Platform-admin role for the deeper admin panels (database setup, video admin).
