Line Crossing Detection

Draw virtual lines on any camera view and count or alert when persons, vehicles, or objects cross in specified directions. Visylix Line Crossing Detection enables accurate entry/exit counting, flow analysis, and perimeter monitoring with per-direction triggering rules.

About Line Crossing Detection

Visylix Line Crossing Detection draws virtual lines on any camera view and counts or alerts when persons, vehicles, or objects cross in specified directions. The model supports multiple lines per camera, each with independent directional rules, object class filters, and counting logic. It combines detection with tracking to ensure accurate crossing attribution even in crowded scenes where multiple objects cross simultaneously. Operators use line crossing data for entry and exit counting, flow analysis, perimeter monitoring, and compliance enforcement. The system outputs real-time crossing events, cumulative counts, and time-series analytics for dashboards and reporting.

Key Features

Engineered for accuracy, speed, and seamless integration into enterprise workflows.

Directional Line Rules

Configure each virtual line with A-to-B, B-to-A, or bidirectional rules for precise directional counting and flow analysis.

Multi-Line Support

Place multiple independent lines per camera, each with its own counters, thresholds, and alert rules for simultaneous monitoring of multiple entry points.

Object Class Filtering

Count or alert only on specific categories per line — persons, vehicles, or other object types — for focused analytics and reduced noise.

Accurate Multi-Object Crossing

Detection plus tracking ensures accurate crossing attribution even when multiple objects cross a line simultaneously in crowded environments.

Real-Time Cumulative Counters

Automatic counter resets at configurable intervals for shift-based, hourly, or daily reporting with real-time streaming to dashboards.

Time-Series Analytics

Crossing counts by hour, day, and week for trend analysis, peak detection, and operational planning with exportable data.

Real-World Use Cases

Deployed across industries to deliver measurable value from day one.

Building Occupancy Tracking

Count entry and exit crossings at building doors for accurate real-time occupancy tracking and fire safety compliance with automatic threshold alerts.

Retail Footfall Counting

Place virtual lines at store doorways for true footfall measurement, enabling conversion rate analytics against point-of-sale transaction data.

Perimeter Monitoring

Detect directional boundary crossings for perimeter security with instant alerts when persons cross lines in unauthorized directions.

Traffic Flow Analysis

Measure pedestrian and vehicle movement patterns at intersections, corridors, and walkways to inform infrastructure planning and optimize flow.
