Introduction
Know Where Crowds Are Gathering. Respond Before Congestion Escalates.
Managing large groups of people is a critical responsibility for shopping malls, transportation hubs, stadiums, exhibition centers, public venues, and other facilities that accommodate significant pedestrian activity.
Crowd conditions can change rapidly. A transportation terminal may experience a sudden surge of passengers, a shopping mall may become congested during a promotional event, or visitors may gather around a popular attraction within an exhibition hall.
Even when the total number of people inside a facility remains within its operating capacity, certain locations may become uncomfortably or dangerously crowded.
High concentrations of people can restrict pedestrian movement, create bottlenecks, complicate emergency access, and make crowd management more challenging.
Traditional video surveillance allows security and facility personnel to observe these situations, but continuously evaluating crowd concentration across multiple cameras is difficult.
Operators may not recognize developing congestion until a particular location becomes heavily crowded.
ACTi Crowd Density Analysis uses AI-powered video analytics to assess the concentration of people within designated monitoring areas.
By automatically identifying areas with increasing crowd density, the solution helps organizations recognize congestion hotspots, monitor changing crowd conditions, and make informed operational decisions.
Where supported by the deployed analytics and monitoring platform, configured high-density conditions can generate real-time events or alerts, enabling personnel to review the situation and respond promptly.
From busy transportation terminals to large public gatherings, ACTi helps organizations improve crowd awareness, support safer pedestrian environments, and manage visitor activity more effectively.
Challenges
Crowds Can Concentrate in Small Areas
A facility may have sufficient overall capacity while certain entrances, corridors, escalator approaches, or gathering points become heavily congested.
These localized crowd concentrations can restrict movement and create operational difficulties.
Facility managers need to understand where people are accumulating, not simply how many people are inside the building.
Crowd Conditions Change Rapidly
Passenger arrivals, event schedules, promotional activities, and unexpected disruptions can cause people to gather quickly.
An area that appears comfortable at one moment may become crowded shortly afterward.
Without timely monitoring, operators may struggle to recognize these changes early.
Congestion Can Affect Pedestrian Safety
High crowd concentration can reduce freedom of movement and complicate access through important pedestrian routes.
In busy environments, crowding near entrances, stairways, escalators, and narrow passages can create additional safety concerns.
Organizations need better visibility into these conditions to support appropriate crowd management procedures.
Manual Crowd Observation Is Difficult
Security teams may be responsible for monitoring numerous cameras covering different parts of a large facility.
Assessing crowd concentration consistently across these locations requires continuous attention.
Important changes may be overlooked when operators are managing multiple responsibilities.
Uneven Visitor Distribution Reduces Comfort
Some areas may attract large crowds while nearby spaces remain relatively empty.
Without information about crowd concentration, operators may find it difficult to improve visitor distribution or reduce congestion.
Limited Information for Crowd Management Planning
Recurring crowding may occur during predictable periods, such as commuting hours, event intermissions, or seasonal shopping peaks.
Without historical crowd density information, organizations may struggle to identify congestion hotspots and plan operational improvements.

Solution Architecture
From Crowd Concentration to Actionable Safety Awareness
ACTi Crowd Density Analysis integrates AI-powered video analytics into existing surveillance and facility management workflows.
IP Cameras → AI Crowd Density Analysis → Crowd Density Information and High-Density Events → Monitoring / Management Platform
Cameras capture video from designated pedestrian areas, entrances, corridors, waiting spaces, and gathering locations.
AI analytics evaluates the concentration of people within configured monitoring regions.
The resulting information helps operators understand crowding conditions and identify areas experiencing higher concentrations of people.
Where supported by the selected ACTi products and software, density information and configured events can be presented through monitoring interfaces, notifications, or historical records.
Security and facility personnel can use these insights to review crowd conditions, identify congestion hotspots, and take appropriate operational action.
Crowd Density Analysis complements other people analytics applications, including People Counting, Occupancy Monitoring, People Flow Analysis, and Queue Analysis.
However, its primary purpose is evaluating crowd concentration within monitored areas, rather than measuring total building occupancy or counting people crossing an entrance.
The system is intended to support operational awareness and existing crowd safety procedures. Density estimates depend on camera coverage and viewing conditions and should not be treated as a substitute for professional crowd safety assessment.
