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).
