Why Choose Metrici

Benefits of Intrusion Detection

From perimeter monitoring to automated response — Metrici AI delivers measurable security improvements across every detection layer.

🛡

Real-Time Threat Detection

AI-powered video analytics detect perimeter breaches, unauthorized access, and suspicious behavior the moment they occur. Instant alerts reach security teams before threats escalate into incidents.

🕐

24/7 Autonomous Monitoring

Every camera feed watched continuously by AI — no operator fatigue, no blind spots during shift changes. Detection performance is consistent around the clock, in any weather or lighting condition.

📊

Reduced False Alarms

Custom-trained DNN models distinguish between humans, animals, vehicles, and environmental noise. Thermal filtering and behavior analysis eliminate the false alerts that plague traditional motion sensors.

🔗

Automated Response

Integrate with barriers, alarms, lighting, and access control systems. When an intrusion is detected, the system can automatically trigger physical responses — closing gates, activating floodlights, or locking down zones.

🏥

Multi-Site Coverage

Deploy across unlimited cameras and zones — from a single industrial site to a distributed network of facilities. Centralized dashboard provides unified visibility across all locations.

Perimeter Breach Detection

Detection · Virtual Tripwire

Virtual Tripwire Technology for Fence-Line Monitoring

Draw a virtual line along any fence, wall, or property boundary. Metrici AI detects the moment that line is crossed — by a person, a vehicle, or an animal — and instantly classifies the threat level.

Deploy virtual tripwires along perimeter fences, walls, and property boundaries — no physical sensors or ground hardware required. The AI boundary is the enforcement mechanism.
Every crossing event is classified in real time — human, vehicle, or animal — so security teams know exactly what they're responding to before they arrive on scene.
Detect not just fence crossings but climbing attempts, digging, and tunneling behavior through AI analysis of movement patterns near the perimeter.
Integrate with physical barriers — when a breach is confirmed, gates can automatically close, floodlights activate, and sirens trigger without human intervention.

After-Hours and Night-Time Perimeter Protection

Perimeter detection operates with the same accuracy at night as during the day — AI compensates for low-light conditions and adverse weather automatically.
Configure different alert thresholds for after-hours periods — loitering near a fence at 3 AM triggers a higher-priority alert than the same behavior during business hours.

🚧

Instant Breach Detection

Virtual tripwires detect perimeter crossings in milliseconds. The alert includes camera snapshot, GPS location, threat classification and elapsed time since detection.

👥

Human vs Animal Filtering

AI distinguishes between humans, animals, and environmental motion. A deer crossing the fence line doesn't trigger a patrol dispatch — only actual threats do.

🔍

Climbing & Tunneling Detection

Not just crossings — the AI detects climbing attempts, digging behavior, and objects placed against fences as potential tunneling tools. Threats are flagged before they succeed.

🔗

Automated Physical Response

Confirmed breaches trigger automated responses — barriers close, floodlights activate, alarms sound, and patrol teams receive GPS-directed dispatch orders.

Unauthorized Access & Entry Control

Detection · People & Vehicle Access

AI-Powered Access Control at Gates and Entry Points

Every gate, entrance, and access point monitored by AI — not just who enters, but whether they should be there, whether they're authorized, and whether their behavior matches expected patterns.

Deploy people detection at all building entrances, service gates, and restricted zone access points — detecting unauthorized individuals before they reach critical infrastructure.
Integrate LPR at vehicle entry points — only whitelisted plates are granted automatic access. Blacklisted or unrecognized vehicles trigger immediate alerts and barrier hold.
Detect after-hours access attempts — the same person entering at 2 PM during work hours is normal; entering at 2 AM without authorization triggers an instant alert.
Monitor for tailgating — when two or more people enter through a single authorized access event, the system flags the unauthorized follower.

Metrici LPR →

Detection · Loitering & Behavior

Loitering Detection and Suspicious Behavior Analysis

Not every intrusion is a fence breach. People lingering near restricted areas, photographing security infrastructure, or testing access points are all threats that require detection and response.

AI monitors for loitering behavior near sensitive areas — individuals remaining stationary or pacing near restricted zones beyond a configurable time threshold are flagged automatically.
Detect reconnaissance patterns — repeated approach-and-retreat behavior near security infrastructure, systematic photography of access points, or testing of door locks and barriers.
Combine people detection with uniform recognition — individuals in restricted zones without the required uniform or safety equipment trigger immediate alerts.
Area Counter monitors occupancy in restricted zones — if people are present when no authorized activity is scheduled, the system alerts security with headcount and location data.

Suspicious Behavior & Object Detection

🧳

Abandoned Object Detection

AI detects bags, packages, or objects left unattended in public areas, lobbies, loading docks, and transit zones. The system tracks how long an object has been stationary and alerts security when it exceeds the configured threshold.

Custom-trained DNN models distinguish between expected stationary objects (furniture, equipment) and newly abandoned items
Alert includes camera snapshot, object location, elapsed time and risk classification — security knows what to expect before arriving
False alarm reduction through environmental awareness — wind-blown debris, shadows, and normal object movement are filtered out

🔍

Suspicious Behavior Pattern Recognition

AI learns normal behavior patterns for each monitored area and flags deviations — people moving in reverse through one-way corridors, gathering in restricted zones, or exhibiting panicked movement.

Behavior models trained on each site's own activity data — the AI knows what "normal" looks like at this specific facility
Phased detection: loitering → pacing → approach to restricted area → breach attempt — each phase triggers escalating alert levels
Multi-camera tracking follows individuals across zones, building a complete movement profile for security review

📍

Unauthorized Equipment & Asset Detection

Detect unauthorized vehicles, equipment, or objects in restricted areas — a delivery truck in a secure zone, construction equipment near a perimeter, or unfamiliar objects placed near critical infrastructure.

Custom object recognition models trained to identify specific vehicle types, equipment classes, and asset categories relevant to your site
Vehicle detection combined with LPR — not just "a vehicle is present" but "this specific unregistered vehicle is in a restricted zone"
Asset movement tracking — if sensitive equipment is moved from its expected location, the system alerts security immediately

Thermal & Night-Time Surveillance

Layer 01

🌡

Thermal Camera

Heat signatures detected through darkness, fog, smoke, and foliage. No visible light required for continuous monitoring.

Layer 02

🧠

AI Classification

DNN model classifies each heat signature — human, vehicle, animal, or environmental — eliminating false alarms from wildlife and weather.

Layer 03

👥

Behavior Analysis

Tracked movement patterns analyzed for threat indicators — approach speed, direction, loitering, or coordinated group movement.

Layer 04

🚨

Alert or Dismiss

Confirmed threats trigger instant alerts with camera feed, classification, and location. False positives logged for model refinement.

🌡

Heat Signature Detection

Thermal cameras detect living beings and warm objects through total darkness, dense fog, smoke, and thick vegetation. No illumination needed — the AI sees heat, not light.

🐾

Animal / Human Filtering

DNN models trained to distinguish human heat signatures from animals, vehicles, and environmental thermal noise. A fox near the fence doesn't trigger a patrol dispatch.

🧠

Concealed Intruder Detection

Thermal imaging detects individuals hiding behind vegetation, inside structures, or attempting to remain visually concealed. Body heat is visible regardless of camouflage or darkness.

💰

Equipment Thermal Monitoring

Beyond intrusion — thermal cameras detect overheating equipment, electrical faults, and fire hazards before they become emergencies. One camera, multiple security layers.

Detection · Thermal Imaging

Thermal AI for Night-Time and Low-Visibility Surveillance

The most vulnerable period for any facility is between sunset and sunrise. Thermal imaging combined with AI classification delivers the same detection accuracy at night that visible-light cameras provide during the day — without any supplemental lighting infrastructure.

Deploy thermal cameras at perimeter fences, blind spots, and areas where visible-light cameras are ineffective — through darkness, fog, smoke, rain, and dense vegetation.
AI classifies every heat signature in real time — distinguishing between humans, vehicles, animals, and environmental thermal events. False alarm rates drop dramatically compared to traditional motion sensors.
Detect concealed intruders hiding behind vegetation, inside abandoned structures, or attempting to use darkness and terrain for cover. Body heat is visible regardless of visual concealment.
Integrate thermal feeds with visible-light cameras — when thermal AI detects a threat, the nearest visible-light camera automatically pans to the location for visual confirmation.
Thermal monitoring extends beyond intrusion — detect overheating electrical equipment, early fire detection, and unauthorized vehicle engine runs in restricted zones.

Multi-Layer Intrusion Detection Integration

🚧

Layered Defense Architecture

No single detection method catches every threat. Metrici combines multiple AI engines into a layered defense system — each layer catching what the others might miss, creating a security net with no gaps.

Outer layer: Perimeter fence monitoring with virtual tripwires and thermal cameras — detect threats at the boundary before they reach the facility.
Middle layer: Gate and entry point control with LPR, people detection, and uniform verification — ensure only authorized personnel and vehicles pass through.
Inner layer: Restricted zone monitoring with Area Counter, loitering detection, and object recognition — detect threats that somehow bypassed outer layers.
Response layer: Automated integration with barriers, alarms, lighting, and access control — physical response triggered by AI detection without human delay.

🔢

LPR + People Detection + Thermal Integration

Combine vehicle recognition, people detection, and thermal imaging into a single coordinated monitoring system. Each technology validates and reinforces the others.

Vehicle approach: LPR reads the plate, classifies the vehicle type, and checks against whitelist/blacklist databases in real time.
Occupant verification: People detection counts occupants in the vehicle — a single-occupancy authorized vehicle with four people triggers an alert.
Thermal validation: At night, thermal imaging confirms the vehicle and occupant count when visible-light cameras are insufficient.
Behavior correlation: If a vehicle circles the perimeter multiple times before approaching a gate, the system flags the pattern as suspicious regardless of plate status.
