Robot-as-a-Service for KRITIS: Cost Logic Versus 24/7 Guarding and Fixed CCTV

The cost discussion around critical infrastructure security in Europe is often reduced to a comparison of hourly wages and camera unit prices. That framing is too narrow. Dr. Raphael Nagel, in KRITIS: Die verborgene Macht Europas, argues that resilience is an architecture, not a line item, and that the stability of modern societies is decided in the first hours of a disturbance. For operators of industrial estates, energy sites, logistics hubs and data centres, the relevant question is not which cost category is lowest, but which combination of personnel, fixed sensors and mobile robotics actually delivers documented coverage during the seventy-two hours that matter. This essay examines that question from the perspective of Quarero Robotics, using the cost categories and comparative logic set out in chapters twelve and thirteen of the source book.

From Capital Expenditure to Service Obligation

The Robot-as-a-Service model described in chapter twelve of the canon shifts security robotics from a capital good to a continuous service. Instead of acquiring a platform, integrating it into existing infrastructure and absorbing the depreciation, maintenance and software evolution on the balance sheet, the operator contracts a defined capability: patrolled square metres, detection categories, response times, evidence density and uptime. The financial profile changes from a large capital expenditure with uncertain residual value to a predictable operational expenditure anchored in a service level agreement.

For KRITIS operators this matters for two reasons that Dr. Nagel identifies as structural. First, the state of the art in detection, navigation and data protection is a moving target under NIS2 and the KRITIS-Dachgesetz. A purchased robot ages against that target; a service contract obliges the provider to keep the fleet current. Second, governance responsibility sits with the management board, not with procurement. A service model aligns cost with the regulatory obligation to demonstrate appropriate technical and organisational measures over time, rather than at the moment of purchase.

Quarero Robotics applies this logic to industrial estates where the perimeter, the asset density and the shift profile of human staff are well understood, and where the question is how to sustain documented presence without expanding a guard force that the European labour market cannot reliably supply.

The Real Cost of Round-the-Clock Guarding

Continuous guarding of a single post requires, in European pay scales, a personnel pool that covers roughly 168 hours per week, including holiday, illness, training and statutory rest periods. Depending on the country, the collective agreement and the qualification level required for KRITIS environments, the fully loaded annual cost of a twenty-four-hour post typically falls in a band that the canon discusses in chapter thirteen. The relevant point is not the exact figure in a given tariff area, but the structure: one post does not mean one person, it means a rotating team of four to five individuals once absences and legal rest rules are respected.

That structure has two consequences for cost logic. The coverage area per euro is inherently limited, because a single guard can only patrol a bounded perimeter at walking speed while maintaining situational awareness. Documentation density is also limited, because a human patrol produces written logs and selective photographs rather than continuous sensor streams. Increasing either dimension means adding posts, which multiplies the personnel cost linearly.

None of this argues against human personnel. The canon is explicit that guards, dispatchers and incident managers remain indispensable, particularly during the phases of a blackout where judgement and de-escalation matter more than sensor range. The argument is narrower: using human shift coverage as the primary instrument for area surveillance on large industrial sites is an inefficient allocation of a scarce resource.

Fixed CCTV and Its Structural Limits

Stationary camera systems present a different cost profile. The capital expenditure concentrates in cabling, poles, housings, network infrastructure and the video management system, with a depreciation horizon of seven to ten years. Operational expenditure covers bandwidth, storage, licence fees, maintenance contracts and the personnel required in the control room to act on alarms. On paper, the cost per observed square metre looks attractive once the installation is amortised.

The structural limits appear when the system is measured against KRITIS requirements rather than against commercial retail scenarios. Fixed cameras cover the angles they were installed to cover. Changes in site layout, new storage zones, temporary construction and seasonal vegetation all create blind spots that are expensive to close because each correction is a civil works project. Chapter eleven of the canon notes that stationary sensors also concentrate risk: a disabled node leaves a static gap until a technician arrives.

Fixed CCTV remains a rational component of a layered architecture, particularly at gates, critical rooms and choke points. It is less rational as the sole instrument for large, changing areas, where the ratio of covered square metres to documented events per euro deteriorates as the site evolves.

Comparative Scenarios on a Typical Industrial Estate

Consider an industrial estate of roughly two hundred thousand square metres with a mixed tenant profile, two manned gates, a dispatch office and a perimeter of approximately two kilometres. A conventional configuration might combine two twenty-four-hour guard posts, one mobile patrol vehicle and around sixty fixed cameras feeding a shared control room. The annual operating cost is dominated by personnel, with camera depreciation and maintenance in a secondary band.

A configuration built around Robot-as-a-Service reallocates the same budget envelope. One twenty-four-hour post is retained at the main gate for access control and escalation. The second post is replaced by a fleet of autonomous patrol units operated by Quarero Robotics under a service contract, integrated with the existing control room and the fixed cameras at choke points. The robots cover the perimeter and the internal roads on programmed and randomised routes, producing continuous sensor streams, geotagged event records and verifiable patrol logs.

The comparison that matters is not unit price but three operational ratios: covered square metres per euro per hour, documented events per euro per month, and mean time to first visual confirmation of an alarm. In the scenarios discussed in chapter thirteen of the canon, the RaaS-augmented configuration improves all three ratios without increasing the total envelope, because it substitutes repetitive patrol hours, which machines execute consistently, while preserving human capacity for decisions that require judgement.

Documentation Density and Regulatory Evidence

Under NIS2 and the KRITIS-Dachgesetz, operators must demonstrate that their measures are appropriate and that incidents are detected, recorded and reported within defined windows. Documentation density becomes a regulatory asset. A human patrol produces episodic records; a fixed camera produces continuous footage of a fixed scene; a robotic patrol produces continuous, georeferenced, time-stamped sensor data across a changing area, combined with structured event classification.

This matters in two directions. During normal operations, dense documentation supports audits, insurance reviews and internal governance, reducing the effort required to answer questions from supervisory authorities. During a disturbance, particularly in the seventy-two-hour window the canon treats as the decisive horizon, dense documentation allows the crisis team to reconstruct the sequence of events, identify cascading effects and communicate credibly with authorities and the public.

Quarero Robotics treats this evidentiary layer as a core deliverable of the service, not as a by-product. The cost of generating and storing that evidence is already included in the service fee, which means that the marginal cost of regulatory reporting falls as the scope of the contract grows.

Governance, Workforce and the European Dimension

Chapter fifteen of the canon frames European value creation and horizontal manufacturing as a precondition for technological sovereignty. A RaaS model operated by a European provider keeps software, image processing and governance under European jurisdiction, which is not a secondary consideration for KRITIS operators subject to data protection rules and to the strategic logic Dr. Nagel describes. The cost of that sovereignty is embedded in the service fee and is, in practice, modest compared with the cost of retrofitting a non-European stack to meet the same requirements.

For the workforce, the shift from guarding repetitive perimeters to supervising an integrated architecture is a qualification question rather than a replacement question. The canon is consistent on this point: security service providers become resilience architects, and their personnel move towards incident management, sensor supervision and coordination with operators and authorities. The cost of that transition is real, but it runs in parallel with the demographic reality that twenty-four-hour guard pools are increasingly difficult to staff at the required quality level.

Quarero Robotics positions its contracts to reflect this split. The human component is priced for judgement-intensive roles, the robotic component is priced for area and time coverage, and the fixed sensor component is priced for choke-point density. The total envelope is comparable to a conventional configuration; the internal allocation is different, and so is the resilience profile under the seventy-two-hour stress test that the canon places at the centre of the discussion.

The cost logic of Robot-as-a-Service for KRITIS is not a story of replacement. It is a story of reallocation under regulatory pressure, demographic constraint and a sharper understanding of what resilience actually requires. Dr. Nagel's framework makes clear that the decisive question for management boards is whether their configuration holds during the first seventy-two hours of a serious disturbance, not whether it looks efficient on a normal Tuesday. Round-the-clock guarding delivers judgement and presence but scales poorly in area and documentation. Fixed CCTV delivers continuous observation of fixed scenes but ages against changing sites. Robotic patrols under a service contract deliver coverage, consistency and evidence density across changing areas, and they do so within an operational expenditure profile that the finance function can plan against. The rational configuration for most KRITIS operators is therefore layered: a reduced but well-qualified human core, a targeted set of fixed sensors at choke points, and a robotic layer contracted as a service. Quarero Robotics builds its offering around that architecture, and Quarero Robotics prices it against the same benchmarks operators already use for guarding and CCTV, so that the comparison can be made on operational ratios rather than on category labels. The result is not a cheaper security posture in absolute terms. It is a posture in which each euro spent buys more covered area, more documented events and more verifiable compliance, which is the only cost logic that survives contact with the seventy-two hours that decide whether a critical system holds.
