Stades et arénasChaque foule et chaque orage, vus depuis la salle de contrôle.
La sécurité d’un stade dépend de la façon dont la foule circule entre portes, coursives et tribunes, et d’une météo qui peut devenir dangereuse. Comptages aux entrées, densité de foule par caméras et météo du site avec alerte foudre, réunis en salle de contrôle, permettent aux responsables de la sécurité d’agir avant que l’affluence ou l’orage ne tournent à l’incident.

Crowds and weather
Stadium safety depends on how tens of thousands of people move through gates, concourses and stands, and on weather that can turn dangerous within minutes. Safety guidance sets capacities and flow rates and puts the control room at the centre. It needs to see crowding and storms early.
Ce qui est mesuré
Counts, density and storms
Counters at turnstiles and gates measure entry and exit flow, cameras over concourses, stands and approaches measure crowd density, a thunderstorm warning sensor watches for lightning, and a weather station measures wind and heat stress for spectators. Each reading carries its time and its quality flags.

- Gate counters · Density cameras · Lightning sensor · Weather station
Le nœud de base
Counting without identifying
The edge server counts people in each zone from camera images without identifying anyone, compares density and flow with the safety plan’s limits, warns of approaching lightning and heat, and keeps an event log for review. Nothing is lost when a link drops; the node keeps it.
Radio et liaisons
Into the control room
Venues have fibre, so cameras and counters reach the control room over it through a security gateway. On event days a private 5G network carries temporary cameras and stewards’ devices. Each link is chosen for the place, not from a catalogue.

- Fibre · 5G privée
Comment ça marche
From a crowded concourse to a held gate
At half-time a concourse fills faster than it drains. Density passes the plan’s limit; the control room holds an entry gate, opens a second route and sends stewards. Density falls within minutes, and the log records every decision. Every step is kept on the record.

Scope with the safety officer
The scope reads the venue’s safety certificate, capacities, zones, control room and past incidents. Nexus Observatory Inc. returns the sensing design, control room integration, privacy design and a price per venue and per year. Every assumption in the scope is written down and priced.

Survey zones and flows
Crews survey gates, concourses, stands and approaches with the safety officer: camera positions for density, counter points, weather and lightning sensor sites and network paths. Findings are recorded with drawings. Every finding is kept with the site record for the crews who follow.
De la commande à l’exploitation · Autorisations
Licensing and privacy
The safety certifying authority is told of the system, privacy rules for cameras are agreed and published, and connections to the control room go through change control. Every approval is kept with the venue record. Approvals are tracked site by site, so nothing waits unseen.
De la commande à l’exploitation · Fabrication
Build and test
Cameras, counters, sensors and the server are configured with zones and limits, enrolled with their identities and tested with recorded crowds before shipping. Test results travel with the kit to the site. Nothing ships until the whole kit has passed its tests together.
Ouvrir le configurateur de stationsDe la commande à l’exploitation · Installation
Install between events
Crews install cameras, counters, the weather station and lightning sensor between events, connect the server behind the security gateway, and add the views to the control room. Every point is recorded. The site record is updated before the crew leaves.
De la commande à l’exploitation · Mise en service
Commission at a live event
Chaque nœud prouve son identité. Counts are compared with turnstile data and manual counts at a live event, density with stewards’ reports, and lightning warnings with the regional service. Results are signed and kept with the site record. Acceptance is recorded with the owner before handover.
De la commande à l’exploitation · Exploitation
Manage the crowd
Safety officers see density and flow in every zone and approaching storms. Gates are opened or held, stewards are sent to crowding before it peaks, and spectators are moved from exposed stands when lightning approaches. Reports for owners and funders come from the same record.
De la commande à l’exploitation · Maintenance
Review every event
After each event the log is reviewed with the safety team, limits and zones are adjusted, cameras cleaned and re-aimed, sensors checked and software updated in rings. Every review is kept. Spares and procedures travel with the crews. Maintenance history stays with each site for its whole life.

For safety officers and authorities
Safety officers and stewards receive density and flow by zone; event control receives lightning and heat warnings; safety certifying authorities receive event logs; venue operators receive capacity reviews, each tied to zone and time. Each product carries its site, time and quality flags.

Guidance for safe grounds
Capacities and flows follow the guide to safety at sports grounds and crowd management guidance, lightning warning follows the thunderstorm warning standard, and heat stress the international index. Every event is logged for the safety certificate. Records are open to the people who must check them.

01Le lieu et ses dangers
Où il fonctionne, et ce qui peut mal tourner.
Operating contextSports grounds are licensed and managed under published safety guidance that sets capacities, crowd flow rates and the role of the control room, and managing crowds safely has its own guidance from health and safety regulators. Thunderstorm warning systems are specified by an international lightning standard.
Dangers
- Crowding at gates, concourses and exits
- Surges and crushes in stands
- Lightning and severe weather during events
- Heat stress among spectators
- Control rooms seeing incidents too late
02Ce qu’il faut mesurer
Quoi, où, à quelle fréquence, et selon quelles règles.
Chaque mesure indique où elle est prise, à quelle fréquence, et la norme ou la réglementation publique qui la fonde. Les numéros de la colonne des sources ouvrent la source citée plus bas.
| Mesure | Où | Fréquence | Sources |
|---|---|---|---|
| Entry and exit flow | Turnstiles and gates | Continuous during events | 1 |
| Crowd density | Cameras over concourses, stands and approaches | Every few seconds | 12 |
| Lightning and storm approach | A thunderstorm warning sensor at the venue | En continu | 3 |
| Weather and heat stress | A station at the venue | Every minute | 45 |
