Crowd Detection

Estimate crowd density and count people accurately in any environment. Visylix Crowd Detection generates real-time density maps, triggers occupancy threshold alerts, and reveals footfall trends that drive smarter venue and public-safety decisions.

About Crowd Detection

Visylix Crowd Detection uses a regression-based density estimation network that outputs a spatial density map for every frame, predicting per-pixel crowd counts without requiring individual person detections. This approach scales gracefully from sparse areas with a handful of people to ultra-dense environments where traditional detectors fail. Zone-based counting aggregates density values within user-defined regions to produce accurate headcounts for each area of interest. Configurable occupancy thresholds trigger instant alerts when counts exceed safe limits, while historical aggregation generates hourly, daily, and weekly trend reports for capacity planning. The model works reliably across indoor venues, outdoor plazas, stadiums, transit stations, and retail floors.

Key Features

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

Density Map Generation

Produce per-pixel density maps that visualize crowd concentration gradients, highlighting hotspots and sparse zones in real time.

Occupancy Threshold Alerts

Define maximum capacity per zone and receive instant notifications when thresholds are approached or breached, enabling proactive crowd control.

Zone-Based Counting

Draw custom polygonal zones on any camera view and receive independent headcounts for each region, from a single doorway to an entire arena section.

Historical Trend Analysis

Aggregate counts over time to reveal peak hours, seasonal patterns, and long-term growth trends for data-driven capacity planning.

High-Density Accuracy

Regression-based architecture maintains counting accuracy in ultra-dense crowds where bounding-box detectors lose reliability due to heavy occlusion.

Multi-Camera Aggregation

Combine counts from multiple overlapping cameras into a unified facility-wide occupancy dashboard with automatic overlap de-duplication.

Real-World Use Cases

Deployed across industries to deliver measurable value from day one.

Event Management

Monitor attendance in real time during concerts, festivals, and conferences. Control entry flow, detect dangerous crush conditions, and verify actual turnout against ticket sales.

Public Safety

Deploy at transit stations, public squares, and protest routes to track crowd size and density. Feed data to command centers for resource allocation and emergency evacuation planning.

Retail Footfall

Measure store-level and department-level foot traffic to evaluate marketing campaigns, optimize staffing schedules, and calculate conversion rates against point-of-sale transactions.

Transport Hubs

Count passengers at platform gates, escalators, and concourses in train stations and airports. Balance load across boarding zones and predict congestion before it impacts schedules.
