Use case · Zone intrusion

Draw the line.Alert when it is crossed.

Fenec detects people, forklifts, and vehicles entering restricted zones, forklift lanes, or maintenance areas at the wrong time.

Why it matters

Danger often happens before the collision.

Near-misses are only useful if the site can see and act on them.

Zones
Precise rules per camera
Draw polygons for lanes, doors, and restricted areas.
Classes
People, forklifts, and vehicles
Different objects can have different rules.
Dwell
Alert only when it matters
Ignore transients and reduce noise.
Workflow

Rules that understand space, class, and time.

The same zone can allow forklifts, reject pedestrians, and change behavior during maintenance.

Polygon zones

Define exact areas directly on each camera view.

Class-specific logic

Allow vehicles while alerting on pedestrians, or the reverse.

Low-latency inference

Local processing keeps alert latency practical.

Escalation rules

Route incidents by severity, shift, and destination system.

Rule examples

Write rules operators can reason about.

Zone alerts should be explicit enough to audit and simple enough to maintain.

Final ROI depends on site workflow, escalation path, and actual incident reduction.

Turn near-misses into usable signals.

Scope a high-risk lane or restricted area and measure whether alerts are accurate enough for operators to trust.

Local processing keeps the privacy review narrow.
