Site
Define the facility boundary and working extent before placing equipment.
Camera Design
Design coverage against the scene, not a flat fan.
Place cameras on a terrain- and obstruction-aware site, inspect the actual optical configuration and keep nominal DORI limits separate from field performance.
01 / Design desk
A map-dominant workflow from site to schedule.
The settled analysis is cancellable and tied to the current camera revision. Editing a camera marks its dependent result stale instead of leaving the previous cone looking current.
Source health
Inspect terrain, surface, structures, vegetation and NoData before trusting a result.
Camera specification
Choose device geometry and make the sensor and lens assumptions visible.
Placement
Position cameras at real mounting heights and orientations around the site.
Optical configuration
Use either sensor-derived optics or manual FOV, never both silently.
Results and schedule
Review current or stale coverage per camera, then prepare a traceable schedule.
02 / What is modelled
Optical geometry and scene obstruction share one frozen context.
The product separates geometric and nominal pixel-density evidence from lighting, focus, motion, compression and other field conditions that software cannot guarantee.
Three-dimensional frustum
Mount height, bearing, tilt, horizontal and vertical FOV and maximum range intersect the sampled scene.
Transparent optical mode
Sensor-and-lens-derived configuration and manual FOV are mutually exclusive and labelled.
Structures and estimated vegetation
Obstruction classes are visible and a DSM does not silently double-count separate clutter.
Inspectable schedule
Position, height, bearing, tilt, FOV, range, source context and result freshness remain reviewable per camera.
03 / Output boundary
Nominal DORI is an input to design review, not guaranteed identification.
A competent CCTV practitioner still needs to confirm mounting, illumination, target behaviour, focus, compression, privacy and measured performance at the real site.
