Control

Your own plans, annotated before anyone arrives.

Upload your own plans and mark them up before the gates: assembly points, cordons, gates, service routes. On the day the live layer draws on top: staff locations, incident pings, and what3words references your stewards can read over the radio. It stays legible when the crowd is the size of a town.

  • Upload your own venue plans: stands, concourses, service routes
  • Annotate before the event: assembly points, cordons, access gates
  • Live layer on top: staff locations, incident pings, what3words refs
  • Clustering keeps the picture readable past 2,000 live markers

Gates open

Gates open.

Stewards hear their zone, supervisors monitor several, control hears everything.

Radios only ever covered the people on your payroll, and one shared frequency covered them with crosstalk. Zone-by-zone rooms for stewards, control, medical and traffic: push-to-talk from a phone in a pocket or a tablet on the desk, presence that shows who is listening at every gate before you speak, and every transmission recorded and transcribed as it happens.

  • A room per zone and per team: stewards, control, medical, traffic
  • Push-to-talk from a phone in a pocket or a tablet on the desk
  • Presence shows who is listening at every gate before you speak
  • Every transmission recorded and transcribed as it happens

Gate 3

A poster at the gate turns the crowd into an alertable, answerable list for the day.

QR posters enrol attendees onto the event’s SMS list in seconds. Join late and you are still covered: a mid-alert sign-up gets the live alert. Instructions go out, “I’m safe” and questions come back, and anyone can report a hazard from the same poster, photo attached.

Control

Something happens; the same rooms, lists and plan carry the response.

Whoever is closest declares from a phone. Every steward’s device sirens, the crowd gets a text with the route and the muster point, the zone board fills in, and the live map shows pings, what3words references and the cordon on your own plan. The whole incident, first report to stand-down, is walked through on its own page.

Gates closed; the day’s record is already written.
