Government buildings, utilities, data centres and transport infrastructure are not protected by more cameras. They are protected by zones, each with a defined job, a defined standard, and a record proving it was met.
A camera specified for a perimeter is the wrong camera for a doorway. Designing by zone means each position has a stated purpose and a measurable standard, rather than a model number chosen from a catalogue.
Detect presence at the boundary and classify it - person, vehicle, or neither. The standard here is reliable detection at range in poor conditions, not facial detail. Thermal and long-range cameras earn their cost in this zone and nowhere else.
Identify vehicles and track movement across open ground. Plate capture at controlled entry, wide overview across car parks and service yards, and enough overlap that a person crossing the site is never handed off between blind spots.
Every door, loading bay and ground-floor opening, tied to access control so that each entry has both a credential record and a matching image. This is the zone auditors ask about first.
Server halls, switchgear, evidence stores, cash handling, controlled substances. Identification-grade coverage, longer retention, and tighter access to the footage itself than anywhere else on the site.
The failure we find most often on existing high-security sites is uniform specification: the same camera at the fence, the door and the server room. It over-specifies the perimeter, under-specifies the critical area, and produces a system that costs more than it needed to while still failing the audit.
Different sectors, one common requirement: the system has to keep working, and it has to be able to prove what it saw.
Municipal and federal buildings, courts and civic sites, with public-access areas that need coverage without over-collection.
Substations, water treatment and pumping stations - often unmanned, remote, and dependent on perimeter detection.
Layered access from fence to cage, with per-rack identification coverage and retention that satisfies client audits.
Long perimeters, vehicle recognition at every gate, and footage that can be matched to a container and a timestamp.
Controlled substance stores, emergency departments and car parks, designed around patient privacy requirements.
Campus perimeters and entrances, with coverage planned so that teaching spaces stay uncovered by design.
On a high-security site the recording is only half the requirement. The other half is being able to show that the system was specified correctly, worked at the relevant moment, and that the footage has not been altered since.
| Record | What it contains | Why it matters |
|---|---|---|
| Coverage plan | Every camera position with its field of view and zone assignment | Proves an area was covered at a given date |
| Commissioning record | Lens, resolution, mounting height, tilt and measured night range per camera | Shows the system met its specification on the day it was signed off |
| DORI classification | Detect / observe / recognise / identify distance for each position | Sets what the footage can reasonably be asked to show |
| Retention policy | Days held per zone, overwrite behaviour, and export procedure | Satisfies audit and data-protection review |
| Access register | Who can view or export footage, and what that action logs | Establishes chain of custody for evidence |
Insurers and investigators increasingly ask for evidence that a camera covered a specific area at a specific time - not simply that cameras existed. A coverage plan and commissioning record turn a contested claim into a settled one. Ask any provider for both before signing, including us.
XEON Security publishes the seven calculations our engineers run before specifying a system. Procurement teams and consultants use them to test whether a tender response is credible before it reaches evaluation.
Why we publish them: a specification that cannot survive these calculations will not survive an incident either. We would rather be evaluated against the physics than against a datasheet.
XEON Security operates from offices in the United States and the Philippines, and serves clients across Lithuania. Briefings, documentation and handover in the language your team works in.
Tell us about the facility and we will arrange a technical briefing - zone model, indicative specification per zone, and what the handover documentation would contain.
