Security Robot Museum: Patrol for Archive and Depot

Security Robot Museum: Why Archives and Depots Require a New Patrol Logic

An average public museum is unsupervised for 14 to 16 hours on weekdays. On weekends the figure is 48 hours straight. In houses closed on Mondays, it reaches 60. During that time the collection depends on fixed sensors, an intruder detection system, and guards who pass through the magazines once or twice per shift.

A 24/7 post costs €15,000 to €25,000 per month in Germany. The spread reflects tariff region, qualification level, and night and weekend supplements under the BDSW wage data. For a mid-sized house that is €180,000 to €300,000 per year for a single staffed position.

Fixed cameras only partially close the gap. Between display case, open storage depot, and climate corridor, dead zones form where no image is captured or where images are not evaluated. Anyone who has tried to monitor a 90-camera stream overnight with one person knows the operational reality.

The second gap lies in damage statistics. Insurers report that roughly 70 percent of notified collection losses stem from fire, water, and climate, not from theft. A patrol optimised only for burglary covers the smaller risk.

A QR-1 patrols silently on programmed routes through galleries and magazines. Noise emission is below the level of the ventilation system. Vibration is not measurable. This makes the robot deployable for the first time in rooms containing parchment, photography, or lacquer painting, where conventional guard rounds with torch and key ring are problematic.

Next step: Full-cost comparison guard service.

Specific Risks: Collection, Depot, Open Storage, Archive Shelf

Showcase theft is a daytime risk, not a night-time risk. Perpetrator groups reconnoitre service routes, emergency exits, and handover points during opening hours. The act itself often takes place shortly before closing, with escape through a prepared emergency exit. Staff presence and access control in service corridors are the most effective countermeasures.

Water damage typically originates from heating pipe bursts in basement depots. Discovery in practice occurs only after 8 to 12 hours, when the shift changes or the climate control triggers an alarm. By then cardboard boxes are saturated, leather bindings have swelled, paper has distorted.

Smouldering fires in archive shelves containing acid paper are particularly insidious. The thermal signature is visible 20 to 40 minutes before smoke develops. Standard smoke detectors activate only once the fire has reached an open phase. By the time the fire brigade arrives, entire shelf rows are involved.

Climate deviations in magazines holding textiles, parchment, or historic photography escalate to conservators within hours. A shift of 5 percentage points in relative humidity overnight can trigger irreversible damage. Building management systems report climate data, but rarely in correlation with an on-site visual check.

Unauthorised access occurs most often via delivery areas, conservation workshops, or roof access points during ongoing construction work. These areas are historically under-represented in camera planning because they are classified as operational space.

Which Sensor Covers Which Risk

The QR-1 for interiors and galleries carries an RGB camera with low-light optimisation and an audio module for detecting broken glass, door impacts, and voices. It covers foyers, galleries, administration wings, and stairwells: areas with controlled lighting. In fully darkened magazines the RGB system reaches its limits.

For magazines, depots, and archive shelves the QR-2 with thermal imaging camera for depots is the correct platform. The thermal sensor detects smouldering fires 20 to 40 minutes before standard smoke detectors. One classification is essential: the QR-2 does not replace the certified fire detection system under DIN 14675. It provides early detection running in parallel to the fire alarm system and creates time for an orderly response.

The QR-2 detects water ingress indirectly. A water pool changes floor temperature significantly relative to the surrounding screed. The robot reports geo-coordinates to the control centre, and the building services team can isolate the affected riser pipe directly. This shortens the typical response time from 8 to 12 hours to under one hour.

Person detection distinguishes cleaning staff carrying a valid day tag from unauthorised presence in magazine areas. Detection operates without biometric identification, using RFID matching and movement patterns exclusively. The system is GDPR-compliant and suitable for works council agreement.

The QR-3 with LiDAR supplements operations in houses with frequent exhibition changes. It maps altered room topologies: shifted display cases, opened archive cabinets, new installations. Deviations from the target state are reported to the control centre. This is particularly relevant for loans whose positions are contractually fixed.

Integration with Conservation and Building Services

The building management interface uses BACnet or Modbus. Climate data and patrol findings then appear in the same evaluation system. A temperature deviation in magazine 3 is displayed together with the most recent thermal image from the QR-2. Conservators make decisions based on both data sources.

Handover to the existing fire alarm system is structured as early detection. When the robot registers a thermal anomaly it sends a signal to the control centre, not directly to the fire brigade. The certified fire alarm line remains unchanged. This separation is non-negotiable: altering it causes both the fire safety officer and the property insurer to reject the configuration.

The patrol log is generated as a tamper-proof PDF. It documents route, timestamps, sensor findings, and events. Insurers, foundation boards, and loan owners receive a verifiable basis. In practice this log replaces the handwritten duty books still maintained in many institutions.

Conservation approval of travel routes takes place before commissioning. The minimum clearance from exhibits is configurable; the standard is 80 cm. In rooms with sensitive floor paintings or historic parquet, specific zones are excluded entirely. Routes are stored as a lock map and are changeable only by two-factor authentication.

Silent mode during concerts, readings, and private views runs via calendar integration. The robot pauses or diverts to secondary routes. Deployment is therefore possible in houses with active event programmes without the audience noticing the robot.

Cost Calculation: Guard Service, Hybrid Model, and Pure Robotics

A 24/7 guard post in a mid-sized museum costs €18,000 per month in full-cost terms. The calculation includes base pay, night, Sunday, and public-holiday supplements, relief cover, training, and dispatch under the BDSW wage structure. In tariff regions with higher pay the figure reaches €22,000.

In the hybrid model a reduced guard post remains staffed during the day, approximately 09:00 to 19:00. At night a QR-2 takes over patrol in magazines and peripheral galleries. Savings amount to €9,000 to €11,000 per month compared to 24/7 full staffing. This configuration is generally accepted by insurers when the patrol log is complete and uninterrupted.

Pure robotics with QR-1 for galleries and QR-2 for depots starts at €6,700 per month on a 24-month contract. The model suits houses whose collections do not contractually require permanent staff presence, such as scientific archives without public access. Details are in the three-tier pricing model.

Under the Robotics-as-a-Service model, CapEx is eliminated entirely. There is no staff recruitment, no sick leave or holiday cover, and no wage increases that must be absorbed mid-budget year. Maintenance, software updates, and replacement units are included in the monthly fee.

Delivery occurs within 48 hours of contract signing. Commissioning, including route mapping and staff training, takes one working week. A comparable owner-operated setup requires six to nine months of lead time from tender. An analogous TCO logic is documented in the hybrid TCO calculation for industrial parks.

Legal Framework: Machinery Regulation, Data Protection, Insurance

The platform complies with the EU Machinery Regulation 2023/1230. The declaration of conformity covers risk analysis, technical documentation, and CE marking. The standard EN ISO 13482 for personal care robots is applied additionally; it defines specific safety requirements for robots operating near persons.

The data protection concept follows the GDPR. No biometric recognition of visitors takes place. Person detection operates without identification, using movement and RFID matching for authorised staff only. This architecture is aligned with the recommendations of the BBK on the protection of culturally relevant infrastructure.

Recording occurs only on an event basis. Routine patrols without anomalies produce no video material. The retention period for event recordings is 72 hours, after which automatic deletion occurs. Longer storage is possible only on a specific order, for example in criminal proceedings.

Insurers accept documented patrol routes as a compensating measure when guard staff are reduced. Prerequisites are tamper-proof logging and integration with the existing intruder detection and fire alarm systems. In negotiations with property insurers, early submission of the configuration is worthwhile: premium adjustments frequently result.

Works council involvement is straightforward when the configuration secures only the perimeter and the collection. Employee monitoring in the sense of performance or behaviour tracking is technically excluded because neither identification nor continuous recording takes place. A works agreement should fix these points in writing.

Pilot Process for a Mid-Sized House

Week 1: Walk-through with security management, conservators, and building services. Definition of risk rooms by collection, depot, open storage, and archive shelf. Determination of excluded zones, such as rooms with floor paintings or open display cases below 80 cm height. Coordination with the fire safety officer on the separation between early detection and the certified fire alarm line.

Week 2: Route mapping with LiDAR. Coordination with conservation on speed, clearance, and time of day. Configuration of alarm thresholds for thermal anomalies, noise levels, and unexpected persons. Connection to the building management system via BACnet.

Week 3: Night trial operation. Cross-checking with the existing intruder detection and fire alarm systems. Test of the escalation chain: robot detects anomaly, transmits to control centre, control centre decides on alerting. False-alarm rate is measured and thresholds are recalibrated.

Week 4: Handover to control centre, training of guard staff on the new patrol logic. Documentation for insurers and foundation board. Initial evaluation of the logs. Transfer of configuration responsibility to the in-house security management.

From month two onward, monthly review of event logs runs continuously. Routes are adjusted after exhibition changes. For larger reconfigurations, such as special exhibitions with altered display-case layouts, the map is re-trained. The effort is two to four hours per adjustment.

For houses with extensive outdoor areas, such as palace museums or sculpture parks, a combination with perimeter protection in detail is appropriate. Inside, QR-1 and QR-2 patrol; outside, weatherproof platforms handle perimeter security.
