In brief
Warehouse security is almost always justified by fear, almost never by calculation. That is a pity, because the calculation is feasible and often favourable. This article gives a five-step method to quantify the annual cost of a poorly protected warehouse, compare it with the cost of an installation, and weigh up on-site guarding against remote monitoring.
Ask a site director what insecurity costs their warehouse. In the vast majority of cases, the answer will come as an anecdote — last year’s theft, the truck that was forced open — and not as an annual figure.
That absence of a number has a direct consequence: the security budget is arbitrated as a comfort expense, competing with investments that do know how to present a return. It almost always loses, until the day an incident pushes it through as an emergency — at the worst possible moment to negotiate.
The method below requires no data you do not already have. It simply requires collecting it from four different departments.
The four cost items nobody counts
Loss of goods is only the first, and rarely the heaviest.
- Loss of goods — what disappears between reception, storage and dispatch.
- Operational disruption — hours lost after an incident: stoppages, re-counts, unplanned stocktakes.
- Insurance costs — premium, the excess you actually bear, and increases applied after a claim.
- Administrative time — internal investigations, police reports, carrier disputes and the search for evidence.
The fourth item often comes as a surprise. On a site handling several delivery disputes a month, the time spent establishing what actually happened on a dock — and the frequent inability to prove it — represents a continuous burden that nobody attaches to security.
The five-step method
- Add up the four items over the last twelve months. Use real figures, even approximate ones. A range is better than an empty box.
- Isolate the avoidable share. Not everything can be prevented by a technical system. Keep the share of events for which upstream detection or video evidence would have changed the outcome. This is the step that calls for honesty; it is also the one that makes the calculation credible in committee.
- Quantify the system as a full annual cost: investment amortised over its useful life, or rental if the installation is leased, plus maintenance and any remote monitoring.
- Compare the two annual amounts. Not the upfront investment against annual losses — that is the classic mistake, and it always skews the comparison against the project.
- Add the non-monetary effects to the decision, without trying to price them: personal safety, workplace climate, meeting customer commitments.
Worth remembering: compare an annual amount with an annual amount. Setting an upfront investment against annual losses is the most common mistake, and it mechanically condemns any security project.
A worked layout
| Item | Last 12 months | Avoidable share |
|---|---|---|
| Loss of goods | — | — |
| Operational disruption | — | — |
| Insurance (premium, excess, increases) | — | — |
| Administrative time | — | — |
| Annual total | — | — |
| Full annual cost of the system | — |
This table is deliberately left blank: it is a layout, not a result. Fill it in with your own figures — that is its only valid use.
A six-line table, presented to an investment committee, shifts a discussion that until then revolved around an anecdote. What matters at that stage is not the precision of the figures, but the fact that they exist and can be compared.
On-site guarding or remote monitoring: framing the comparison
Many logistics sites fund night-time guarding. The question is not whether a human presence is useful — it is — but whether it is deployed in the right place.
A remote video patrol consists of scheduled sweeps carried out by a remote operator across a site’s cameras, at times when it is unoccupied, with alarm verification and a defined alert procedure.
It does not replace a guard where a physical presence is required — reception, opening up, immediate intervention. It does, however, efficiently replace passive patrol hours.
To compare honestly, bring both options back to the same annual hourly scope and include, on the human side, the full cost of a position covered continuously — which implies several full-time equivalents for a single night position. It is that calculation, and not the advertised hourly rate, that gives the right order of magnitude.
We do not publish a generic profitability ratio: it depends too much on the number of sites, the hours covered and the video installation already in place. A significant gap in favour of remote monitoring is common on sites that are unoccupied at night, but it has to be verified site by site, not stated as a general rule.
What the calculation leaves out, and what it weighs
The ability to retrieve a sequence. In a delivery dispute, the value of a system lies not in the number of cameras but in how long it takes to find the right load, at the right time, on the right dock. Going from two hours of searching to two minutes changes the nature of the tool: it becomes usable day to day by operations, and not only after a loss.
Insurance negotiation. A documented system, with written procedures and usable evidence, is an element of discussion with your insurer. Rarely decisive on its own, never useless.
The effect on internal discrepancies. This is the least comfortable subject, and one of the most decisive in the results observed on warehouses.
Frequently asked questions
How do you calculate the cost of a poorly protected warehouse?
In five steps: add up, over twelve months, loss of goods, operational disruption, insurance costs and administrative time; isolate the share genuinely avoidable through a system; quantify the system as a full annual cost; compare the two annual amounts; then add non-monetary effects such as personal safety to the decision.
What is the most common mistake in this calculation?
Comparing the upfront investment in the system with the losses of a single year. Both terms must be brought back to an annual amount: investment amortised over its useful life, or rental if the installation is leased, including maintenance and remote monitoring.
What is a remote video patrol?
It is a scheduled sweep, carried out remotely by an operator across a site’s cameras at times when it is unoccupied, with alarm verification and a defined alert procedure. It efficiently replaces passive patrol hours, but not duties that require a physical presence on site.
Which cost items are most often forgotten?
Insurance — premium, the excess actually borne and increases after a claim — and the administrative time spent on internal investigations, police reports, carrier disputes and the search for evidence. That last item is a continuous burden rarely attached to security.
Does a security system reduce insurance premiums?
Not automatically. A documented system, with written procedures and usable evidence, is an element of discussion with the insurer. It is rarely decisive on its own, but it carries weight in the negotiation, particularly after a claim.
