The round that actually happens at three in the morning

Night rounds on industrial sites, substations, landfills and data centres. The platform drives the route by itself, reports deviations to the control room and returns to its charging station.

The situation

Even the failed attempt is expensive

Metal theft from infrastructure has a particular damage pattern: even a failed attempt causes the full consequential damage. If a cable is cut and left behind, the installation is still down until it has been repaired. At Deutsche Bahn, Germany’s national railway, repair costs in a single year added up to around 15 million euros, with just under 11,000 delayed trains as a result.

From this follows something uncomfortable: identifying the offender afterwards is of little use. The only thing that works is noticing the attempt early enough — or not making it attractive in the first place.

The second reason is more prosaic. A night round across an extensive site is not difficult, just long and always the same. That makes it exactly the kind of task that gets thinned out first when staff are short — and whose absence nobody notices until something happens.

Procedure

Teach it once, then every night

  1. Teach the route. The platform is driven across the site manually once. Checkpoints, viewing directions and stopping positions are defined.
  2. Run it unaided. From then on it drives the round at the set interval — several times a night if need be, at weekends, in the rain.
  3. Report deviations. What goes to the control room is not the normal case but whatever departs from it: a person in the area, an open gate, a heat source where there should be none.
  4. Back to the station. After the round the platform returns to the docking station and is ready for the next one.

The difference from a fixed camera lies not in image quality but in coverage: a moving machine sees behind the building, into the alley between the transformers and along the back of the fence — places that would otherwise each need a mast of their own.

Detection

What the platform watches for

People and movement

Camera with zoom and lighting that switches on as needed, plus thermal imaging — at night the more reliable signal, because a person stands out against the cold background even when not moving.

Conditions on site

Open gates and doors, damaged fences, toppled containers, leaks, fill levels. Much of this is an operational rather than a security matter — and comes as a by-product of the same round.

Change since yesterday

Because every round captures the same points from the same position, a comparison emerges. A deviation stands out even if nobody knew what to look for.

Legal framework

What has to be settled before procurement

Legally, a patrolling camera is a video surveillance system — with everything that entails. This is not small print; it is the point where projects of this kind fail if it comes up too late.

What follows is the position in Germany. Other countries have their own rules on video surveillance and employee monitoring; the principle is the same everywhere — settle it before the first machine drives.

  • The works council has a say. Under section 87(1) no. 6 of the German Works Constitution Act (BetrVG), employee representatives have a right of co-determination over the introduction and design of any system capable of monitoring the conduct or performance of employees. Without their agreement, no camera goes into operation.
  • Necessity and proportionality. The deeper the intrusion into personal rights, the more weight those rights carry. Areas mainly used for private life are excluded in any case.
  • Retention period. German data protection supervisory authorities generally regard a maximum of 72 hours as justifiable. Anyone wanting to keep footage longer needs a sound reason.
  • Mistakes are expensive. Under Article 82 GDPR, data subjects can claim compensation, including for non-material damage.

In practice this means: route, viewing directions, evaluation logic and retention belong in a works agreement before the first machine drives. We supply the technical details you need for it — the agreement itself is concluded in-house.

Limits

What the platform is not

  • Not a security guard. It confronts nobody, stops nobody and does not intervene. It reports — and someone has to be able to respond to that report. Without that chain it is an expensive recorder.
  • No substitute for fence and lock. Mechanical security remains the first layer; the patrol adds time and area to it, it does not replace it.
  • Weather and ground limit the route. Snow, deep puddles and loose fill are manageable for a tracked vehicle, but not without consequence — the route has to suit them.
  • False alarms cost trust. A system that raises an alarm three times a night because of a fox will be ignored after two weeks. The evaluation logic matters more than the camera.
Configuration

A typical patrol platform

In this application the docking station is not an accessory: without it, every round needs someone to fetch the machine and plug it in — which means exactly the staff time that was supposed to be saved.
