Event Guardian Visitor App
The event in your pocket — and help where it's needed in an emergency. The visitor app combines orientation, service and safety and contributes — data-minimised and optionally anonymous — to the event's digital situational picture. No personal user account is required.
> Status: in development
The Event Guardian Visitor App is part of the Event Guardian system and is under active development. The functions described here show the planned feature set. We are admitting organisers, security providers and municipalities to the early-access programme for pilot projects and early access.
Activation without an account
The app can be activated directly for an event — no registration — via:
- a QR code on the ticket
- a link from the organiser
- a QR code at the entrance
- the event website
- public app stores
Practical functions for visitors
The app accompanies the visitor before, during and after the event:
- interactive site map and personal programme
- navigation to stages, halls, areas, toilets and accessible facilities
- food and drink stands, waiting times, free entrances
- free parking areas and public transport information
- weather warnings and safety and conduct notices
- alerts about closed or overcrowded areas, routing via safe paths
- lost & found, loss reports, reporting of defects and soiling
- emergency and help function with precise localisation
Anonymous live monitoring
With the visitor's consent, the app contributes anonymised data about the current situation — not the identity of individuals, but aggregated information such as visitor count per area, directions of movement, dwell time, waiting times, load on routes and entrances, and unusual crowd density.
Event Guardian combines this with further sources — ticket scanners, counting sensors, camera systems, drones, Wi-Fi measurements, parking sensors and staff reports — into a more precise situational picture, without recording individual visitors by name.
The area in front of the main stage is expected to reach its defined capacity limit within the next 15 minutes. Visitors should be guided to alternative areas via the app.
Emergency & AI-assisted initial assessment
In an emergency, the visitor requests help via a clearly visible button — with precise position, type of emergency, number of people affected, description, photo, voice and chat. Depending on the venue, the position is determined from GPS, zone data, Bluetooth beacons, Wi-Fi positioning, fixed QR codes or seat details.
The AI supports the structured assessment of the report, recognises visible cues in a photo and asks the visitor simple follow-up questions. It does not make a medical diagnosis — it supports initial assessment and prioritisation for trained responders. Medical notes come exclusively from pre-approved first-aid content.
Automatic routing to the right team
Through the Event CMDB and the live situational picture, Event Guardian knows the position, qualification, load and availability of the medical and security teams. The system determines not just the nearest, but the fastest available and professionally suitable team — and transmits the assignment directly to mobile devices after confirmation. Final approval remains with the operations management.
Privacy by Design
- use without a personal account, no facial recognition
- no permanent identification — anonymous or pseudonymous device session
- voluntary consent to location and sensor use, transparently explained
- separation of emergency data and general analytics data
- encrypted transmission, limited retention, automatic deletion
- operation on controllable infrastructure
Who it's for
- Visitors — orientation, up-to-date information, shorter waiting times, fast help in an emergency
- Organisers — a more precise situational picture, earlier bottleneck detection, more efficient deployment control, documented processes
- Response teams — a precise location, a structured report, photo, suitable routing, clear prioritisation
