Perimeter Intrusion Detection
Detects people, vehicles, vessels and drones approaching or crossing a site boundary — fence climbing, fence-line crossing, after-hours movement — and flags each event as it happens.

What it detects
Long, hard-to-staff perimeters are where most sites have the least observation per metre. These are the boundary events Fogsphere identifies on existing fixed and thermal cameras.
Fence-line crossing
Identifies a person crossing the boundary line, with the fence segment, camera and direction of travel logged against the event.
Fence climbing
Flags climbing behaviour at the fence, gate or wall — including attempts that stop short of a full crossing.
Vehicle breach at the boundary
Surfaces vehicles approaching, stopping at or forcing the fence line, with vehicle classification where the view allows it.
After-hours boundary movement
Detects presence and movement along the perimeter during the hours the site is configured as closed, on a per-zone schedule.
Waterside and vessel approach
Identifies small craft, supply boats and unauthorised vessels approaching offshore platforms, jetties, intakes and dam perimeters.
Drone and UAV presence
Flags drone activity over and around the boundary where camera placement and sensor support allow it.
Wildlife and weather filtering
Separates animals, blowing debris, rain and moving vegetation from human and vehicle events, so the alarm stream stays reviewable.
Laydown yards and temporary fence lines
Covers gates, laydown areas and shifting site boundaries, and adapts as temporary barriers are moved during a project.
Barrier and fence condition
Surfaces damaged fencing, gaps, downed sections, open gates and vegetation encroachment that reduce the boundary’s effectiveness.
Thermal and low-light coverage
Runs on thermal streams alongside visible-light cameras so boundary events remain detectable at night and in poor visibility.
Where it applies
Perimeter monitoring appears in every Q3 market paper. Coverage priorities differ — long refinery fence lines, shifting construction boundaries, retail forecourts, substations, hospital grounds — but the detection set is the same.
How it works
Edge inference on the cameras you already have
Boundary detection runs on the site’s existing fixed, PTZ and thermal cameras. Inference happens on-site, so long fence lines can be covered without streaming continuous video off the network.
Zones, thresholds and schedules you configure
Draw the boundary line and buffer zone on each camera view. Sensitivity, minimum dwell before alarm, and active hours are set per zone, per day, so a working yard and a closed-out area behave differently.
Every event carries its own evidence
Each detection is logged with a timestamp, the camera and zone it came from, and a short clip. The record can be reviewed, exported or attached to an investigation without trawling through hours of footage.
Feeds the systems already in place
Events surface in Fogsphere Manager and route outward to the VMS, access-control platform, control-room wallboard, ticketing queue or messaging channel operators already watch.
Risk & control objective
The control objective is boundary awareness, not physical hardening. Fences, gates and barriers define where the site ends; what most operators lack is a reliable, continuous record of who and what has approached or crossed that line, and when.
Perimeter length is the underlying economics problem. A refinery, tank farm, substation, logistics park or construction site can run to kilometres of fence, most of it out of sight of any staffed position. Manned patrols sample it; cameras cover it continuously but produce more video than anyone can watch. Fogsphere sits between the two — the cameras stay where they are, and the operator receives boundary events rather than boundary footage.
Alarm quality is the second half of the objective. A perimeter system that reports every fox, gust and rain squall gets muted within a week. Filtering wildlife, weather and vegetation is therefore not a refinement; it is what makes the boundary record usable as evidence and as a daily operational signal.
