Tank-farm fence, night
PIDS segment 7 plus camera 12 confirms a person crossing within 5 seconds. High: floodlight, siren, patrol, record. PIDS-only: Low.
Integrations
Alerts that do something, and sensor fusion that makes them trustworthy.
Standalone sensors cry wolf. Standalone video does too. A verified alarm is two independent signals that agree, mapped in space and time.
Why video alone, and sensors alone, fail
Fence PIDS and PIR trip on wind, rain, loose panels, animals and vegetation. The UK NPSA notes that PIDS are prone to false alarms, and that over-sensitive systems produce too many alarms to verify. Video analytics alone false-alarms on shadows, rain, insects on IR illuminators, headlight glare and moving foliage.
How fusion fixes it
AND/OR logic. Temporal correlation windows. Spatial mapping of sensor zones to camera fields of view. Confidence from model score, sensor agreement, temporal and spatial match, and environmental context.
The scale of the problem
Securitas Technology reports traditional alarm monitoring produces a 98% false-alarm rate. Pelco/Calipsa and Lumana report that video verification cuts false alarms by up to 90%. Fusing verified video with a corroborating sensor pushes reliability further.
A verified alarm is at least two independent signals that agree. Only verified alarms are dispatched.
Confidence tiers gate actions
Low
Log. A single noisy signal stays in the record.
Medium
Notify. A supervisor or NOC sees it.
High
Actuate. Barrier, siren, PA, dispatch.
Optional human-review tier for irreversible actions. Customer-configurable. Off by default.

Four worked examples
Unmanned tower site
Fuel-level drop plus a person at the genset, and no service-vehicle telematics. High: siren, NOC, dispatch, signed record. Drop during a booked refuel with matching telematics: Low.
Substation corridor point
SCADA 132 kV fault plus visual at the nearest covered tower base. High: NOC and police liaison, record. Fault with no visual during a weather event: Medium.
Hostel door during curfew
Door contact at 02:00 plus unmatched entry on camera plus a nearby blue-light. High, routed through optional review before any campus-wide notification.
It cannot make a camera see what it is not pointed at, and it cannot identify people or intent. It can tell you, with a confidence you can act on, that something is where it should not be.

Questions
- What is a verified alarm?
- At least two independent signals agree: for example a PIDS segment and a person crossing in the matching camera field of view within a few seconds.
- Do you replace our VMS or SCADA?
- No. Outputs include VMS, SCADA, BMS, PLC, ticketing and webhooks. We sit on the cameras you already run.
- Is human review required before an action?
- No. Review is an optional tier for irreversible actions (evacuation call, weapons response, regulator submission). It is customer-configurable and off by default.
- Does fusion identify people?
- No. Fusion cannot identify people or intent. It can tell you, with a confidence you can act on, that something is where it should not be.
