Critical Infrastructure

Plan substation camera coverage with nominal DORI / PPM zones.

SighThor gives security designers a terrain-aware camera planning workflow for substations and critical infrastructure, with IEC 62676-4 reference thresholds and draft, watermarked design evidence.

Start FreeCamera Coverage Overview

Pain Points

Why critical infrastructure camera plans need more rigour

Small sites with high-value assets leave no room for coverage assumptions that have not been tested against real geometry.

Substations are compact, high-value sites where a single blind spot can be the difference between detecting an intruder and missing a critical breach.
Clients and insurers may require documented design assumptions rather than camera symbols alone on a site plan.
PTZ cameras mounted at elevation interact with terrain and structures in ways that flat-plan drawings cannot reliably predict.

Capabilities

What the substation workflow delivers

Designed for the specific challenge of proving camera coverage on compact, high-consequence sites.

Terrain-aware site coverage

Coverage analysis accounts for ground elevation changes, embankments, and equipment plinths that affect camera sight lines within the compound.

Nominal DORI / PPM review

Compare calculated PPM thresholds at perimeter and asset positions. Nominal zones do not guarantee detection or identification in field conditions.

PTZ at elevation modelling

Model PTZ cameras at pole and gantry heights to compare tilt and zoom presets with the configured nominal DORI band.

Draft design evidence

Prepare watermarked reports, camera schedules, and geospatial overlays for client, auditor, and competent-person review.

Security standard alignment

Camera analysis references IEC 62676-4 DORI thresholds and configured sensor and lens inputs; field performance still requires validation.

Workflow

From site plan to configured-threshold findings in four steps

A focused workflow for sites where every camera position must be justified.

  1. 01

    Create a project and navigate to the substation or infrastructure site on the satellite map.

  2. 02

    Place cameras at mounting positions — perimeter poles, equipment gantries, building corners — and configure height, bearing, and tilt.

  3. 03

    Run nominal DORI analysis to compare recognition and identification thresholds across perimeter fence lines, transformer bays, and access points.

  4. 04

    Prepare the coverage map, camera schedule, and configured-threshold findings for utility operator and security reviewer checks.

Turn a site brief into an inspectable planning draft.

Start with terrain-aware geometry, then review every source, limitation and field check.
