Case study: a 1.2 km family festival without cables

At first glance, a family festival looks straightforward: stalls, stages, fairground rides, plenty of children and a relaxed atmosphere. For safety planning, it is often the opposite. The crowd is mixed, families move slowly and like to stop, and on a large site visitors spread out unevenly. The key question is this: how does event management keep track of a site that stretches for more than a kilometre – and how does it reach every visitor if something goes wrong?

This article uses the Rhein-Kreis Neuss family festival at Schloss Dyck to show how such a task can be approached, and draws out general lessons for organisers.

The starting point

The family festival took place in the grounds of Schloss Dyck. The key facts:

Feature	Value
Visitors	25,000
Site	1.2 km
Cable laid	0 metres
Event duration	1 day
Set-up and dismantling	two days in total

A site of this size brings familiar difficulties. There is no single vantage point from which the whole area can be seen. Distances between zones are long, and event management at one end often hears about events at the other only after a delay, by radio. On top of that, running cables across large areas takes time, and fixed power and network connections are rarely available everywhere on open ground.

The basics: what a large site demands

One situational picture, not many separate feeds

Lots of camera images do not add up to a situational picture. What matters is that decision-makers can spot unusual crowd movements and developing situations, keep access routes for the emergency services in view, and know where they can inform visitors. On an elongated site, that means cameras must be placed where the situation can change – along paths, at pinch points and at meeting places – and their images must come together in one place.

Reaching visitors

A situational picture is of little use if event management cannot act on it. On a large site, loudspeaker announcements are the fastest way to inform or direct visitors. Yet announcements compete with music from stages and rides. For a safety announcement to get through, that music has to be interruptible. More on this in our article on event announcements.

Independent of cables, mains power and mobile networks

Safety infrastructure has to work precisely when things go wrong: during a power cut, when networks are overloaded, or when crowd flows suddenly change. On a site without continuous infrastructure, a wireless system with its own power and its own network is therefore not a convenience but a prerequisite.

The deployment in practice

Live situational picture

Mast-mounted cameras delivered a live situational picture of the festival grounds. According to our reference list, seven cameras were in use, connected to MOVETOS OPS. Rather than a loose collection of separate views, the images came together as a single shared picture. Even when nothing happens, such a picture has value: event management can see in real time how crowds are moving, where pinch points are forming and whether areas have been cleared.

Loudspeaker announcements and interrupt systems

Loudspeaker announcements were available for visitor management – via the masts and a visitor announcement system (BDS), a free-standing loudspeaker column. Interrupt systems were connected in the fairground rides, so an emergency announcement cuts into the music instead of being lost in it.

Remote workstation in the event management office

The situational picture did not stay in a control room on site. A remote workstation brought it directly into the event management office. The people taking decisions therefore saw the same situation as the technical team – without relaying it by radio or phone.

Automated area monitoring and the night watch

A large event does not end with the last visitor. Overnight, stalls, stages and equipment remain on site and need guarding. At the family festival, automated area monitoring supported the night watch, with a robot carrying out automated surveillance of the grounds at night. Security staff need not patrol every corner of a 1.2 km site on foot.

Set-up and dismantling in two days

Set-up and dismantling took two days in total – without a single metre of cable being laid. The masts bring their own power and radio links, so there is no need for trenches, cable ramps or trip hazards on footpaths.

How MOVETOS approaches it

The Neuss example follows one principle: define the safety function you need first, then choose the technology. What is needed is a reliable situational picture, a way to reach visitors in an emergency, and communication that holds up even when networks are overloaded.

The MOVETOS SET consists of masts with camera, lighting and loudspeaker – independent of mains power and external networks, connected wirelessly. Where only announcements are needed, the BDS extends coverage. The MOVETOS OPS platform brings everything together: camera images and crowd density per area on one map, in the control room, on a laptop and on a phone.

More generally, MOVETOS OPS offers:

• Live detection: crowd density, a person in a restricted area and unattended luggage. When a warning is raised, a photo is stored as evidence; there is no video recording. Analysis runs on site, with no cloud required.
• Restricted areas: zones such as a roadway or a fence line can be drawn on the map; anyone entering them is reported.
• Announcements in five languages, even without internet access. When the platform detects a critical situation, it proposes a suitable announcement. The system proposes, a person approves.
• Integrating third-party sound: an interrupt box brings the sound systems of fairground rides, stages and other third parties into emergency communication – the announcement interrupts the music.
• Team coordination even without mobile coverage, over the local network on site.
• Documentation: the event is documented in full.

How masts, cameras and radio links are planned across a site is covered in our article on planning cameras, loudspeakers and radio links.

What organisers can learn from it

Start from the task. A camera here and a loudspeaker there do not make a safety infrastructure. First ask what event management needs to see and whom it needs to reach.

Cover the whole site. On elongated grounds, the critical points are often far apart. The situational picture and announcements must reach the far end too.

Involve the decision-makers. The situational picture belongs where decisions are made – if necessary as a dedicated workstation in the event management office.

Plan for the music. Rides and stages have their own sound systems. Without an interrupt, an emergency announcement can be lost.

Don’t forget the night. Between event days, or once the festival is over, the site still needs protecting. Automated monitoring takes pressure off the night watch.

Allow for set-up and dismantling. Wireless, self-sufficient equipment shortens these windows and spares sensitive grounds.

Checklist for your event

• Map the site: how large and how elongated is it? Where are the paths, pinch points, stages and emergency access routes?
• Plan the situational picture: do the cameras cover every area where the situation could change?
• Bring the picture to the decision-makers: does event management see the situational picture itself?
• Cover announcements: do loudspeakers reach every visitor area, including the edges?
• Interrupt the music: can rides and stages be muted for safety announcements?
• Think through failures: does everything still work during a power cut or when mobile networks are overloaded?
• Secure the night: how is the site monitored outside opening hours?
• Check the schedule: do set-up and dismantling fit the time available?
• Settle documentation: are warnings and announcements recorded in a traceable way?

Conclusion

The Rhein-Kreis Neuss family festival shows that even a large, elongated site with 25,000 visitors can be secured without a single metre of cable. What made the difference was not any single camera or loudspeaker but how the parts worked together: a live situational picture that reached all the way into the event management office, announcements that could cut through the music of the rides, and automated monitoring that carried on through the night. Set-up and dismantling in two days make it clear that such infrastructure can be temporary – there for exactly as long as it is needed.
