Artwork Protection at Kunstmuseum Stuttgart with Isarsoft

Challenge: Displaying art while protecting it

Making art open, transparent, and accessible to everyone is central to Kunstmuseum Stuttgart's mission. But barriers, cordons, and display cases work against that goal. They interrupt sightlines, alter the spatial experience of a room, and turn the museum from a living space for cultural exchange into something more clinical and closed off.

Yet without some form of protection, day-to-day museum operation regularly produces risky situations:

• Unintentional over-approach: Visitors lean in closer to paintings to study brushwork or fine detail, often without realizing how close they've gotten.
• Direct interaction: Children, or simply inattentive visitors, try to touch a canvas or sculpture to feel its texture.
• Reaction latency: Human security staff cannot watch every corner of every gallery at all times. By the time an incident is noticed, the reaction window has often already closed.

This is a challenge every museum, gallery, and cultural institution faces to some degree. The task at Kunstmuseum was to build a precise, contactless, and effectively invisible layer of monitoring.

Why exhibit protection matters more than ever

Artwork protection isn't a cosmetic concern. A single unauthorized touch to an unvarnished canvas, a fragile pastel, or a textured surface can trigger months of conservation work and in the worst cases, cause damage that is never fully reversible. As visitor numbers at major museums continue to grow, and as collections increasingly include contemporary, tactile, or unconventional media that don't fit neatly behind glass, the operational pressure on traditional exhibit protection methods keeps increasing.

Conventional approaches to exhibit protection

In many museums and galleries, manual surveillance by security staff - positioned directly in the gallery or watching camera feeds from a control room - remains the default. In practice, this creates several structural problems for operators:

• High staffing requirements:
  Securing critical zones means posting staff rigidly at fixed positions. Covering an entire exhibition floor this way requires a large security workforce, driving up operating costs significantly.
• False alarms: Traditional light barriers, laser-based systems, or fixed sensors are inflexible, expensive to install, and prone to triggering on ordinary foot traffic. Frequent false alarms desensitize security staff over time, leading to "alarm fatigue," where real threats risk being missed because staff have learned to discount the system.
• Risk to the artwork itself: Any physical contact with an exhibit can trigger extensive, costly conservation work and, in the worst case, cause permanent damage to irreplaceable pieces.

None of these approaches solve the underlying tension: protection at the cost of either the visitor experience, the budget, or both.

The solution: Exhibit protection with Isarsoft Perception

To protect valuable exhibits efficiently and invisibly, Kunstmuseum Stuttgart's technical department set out to find a reliable, automated alternative to manual and sensor-based surveillance. In a successful pilot project, Isarsoft demonstrated both the performance of its software and how seamlessly it integrated into the museum's existing infrastructure.

Across multiple test series, the software reliably detected approach and touch attempts on paintings and exhibits. This gives the museum an effective, visitor-invisible form of exhibit protection. As Isarsoft works with the museum's existing camera infrastructure, it does so without a major hardware investment or added strain on facility planning.

Implementation

Exhibit protection via video analytics becomes effective through three core mechanisms:

Virtual protection zones

Using Isarsoft Perception's interface, the team defined digital, invisible restricted zones directly over plus just a few centimeters in front of each painting.

Real-time precision with AI

Isarsoft's deep-learning algorithms distinguish precisely between a visitor moving normally through the room and a hand reaching deliberately toward a painting. This distinction is the difference between a system that's actually usable day-to-day and one that cries wolf so often that staff learn to ignore it.

Two-stage alarm logic

• Stage 1 — Warning: If a person crosses the invisible boundary, a subtle audio cue prompts them to step back.
• Stage 2 — Alarm: If someone reaches directly toward the artwork, an alarm — including a live image of the situation — is sent immediately to security staff.

Continuous project optimization and fine-tuning

Throughout the project, the Isarsoft team worked closely with Kunstmuseum Stuttgart's stakeholders to continuously refine the system. The goal was to maximize the detection rate for touch attempts specifically.

To get there, the system evolved from an initial, classic bounding-box model to a pose-based model that recognizes a person's skeletal structure. With this refinement, a touch attempt is now only flagged once a hand specifically approaches the artwork cutting down on triggers caused by a visitor simply standing or walking nearby.

Results

With the successful rollout of Isarsoft Perception, Kunstmuseum Stuttgart has established a precise, reliable safeguard for the preventive protection of its exhibits. For museum management, this translates into concrete operational relief and cost savings:

• Security staff relieved from monotonous static watch duty, allowing more flexible and effective deployment.
• Art stays the focus, protected by technology that works quietly in the background rather than visible barriers that compete with the exhibition itself.

Rudi Schweizer, responsible for the technical project coordination at Kunstmuseum Stuttgart, was primarily in charge of the strategic procurement and successful operational rollout of Isarsoft Perception.

He draws an entirely positive conclusion about the project:

With Isarsoft, we can preserve the inviting, open atmosphere for our visitors while increasing preventive security for our masterpieces. Thanks to the accuracy of the detection and the resulting reduction in false alarms, we're able to relieve the burden on our security staff.

Rudi Schweizer, along with Sandro Nerz (Technical Lead) and Michael Brandt (Technician at partner company Jans Group), particularly value the professional, collaborative partnership with the Isarsoft team.

How museums worldwide protect exhibits with video analytics

The successful implementation at Kunstmuseum Stuttgart is a clear example of how video analytics software turns the operational challenges of exhibit protection into measurable advantages. The core benefits of Isarsoft Perception can be summarized as follows:

1. Maximum cost efficiency through existing infrastructure:
   The software runs directly on the museum's already-installed camera infrastructure. This drastically reduces investment costs and guarantees an extremely fast time-to-market.
2. Automation instead of manual effort:
   Error-prone, staff-intensive manual observation is replaced by seamless, fully automated, continuous exhibition monitoring.
3. Reaction time:
   Approach attempts and unusual behavior are detected by the software in real time. Visitors are alerted via a discreet acoustic signal, or security staff are notified immediately.
4. Invisible protection:
   Virtual rather than physical barriers guarantee an unrestricted experience for museum visitors.
5. Data privacy:
   100% GDPR-compliant, since the system processes metadata only, without any personal identification. Privacy is fully preserved at every stage.

Technology comparison: video analytics vs. sensor-based solutions

A direct technology comparison based on the Kunstmuseum Stuttgart project illustrates the significant advantages of AI-based video analytics over classic hardware sensors.

While video analytics flexibly taps into a museum's existing security camera infrastructure, sensor-based approaches typically require costly acquisition of new hardware, more elaborate installation processes, and additional cabling.

The direct comparison at Kunstmuseum Stuttgart — based on an assumption of 4 sensors required per exhibition room — breaks down as follows:

Future developments at Kunstmuseum Stuttgart

Looking ahead, Kunstmuseum Stuttgart is undergoing the largest modernization in its history. After more than two decades of continuous operation, the museum closed its doors in April 2026 for a comprehensive renovation, bringing its entire building technology and hazard detection systems up to current standards by early 2027.

The overhaul was unavoidable: the museum's aging infrastructure could no longer keep pace with modern security and technical standards for exhibition operations. That the museum was already prepared for this next step was demonstrated by its earlier, successful exhibit protection project with Isarsoft Perception. For the modernized museum, AI-powered video analytics is set to remain a key digital cornerstone helping the institution stay securely positioned for rising visitor numbers over the long term.
