Detection

Crowd Density Monitoring

Monitor occupancy levels, flow patterns, and dangerous overcrowding across your venue in real time. Archangel provides evacuation readiness scoring and capacity alerts.

How It Works

Under the hood

Archangel's crowd monitoring system counts and tracks people across your camera network without identifying anyone. It builds a real-time density heatmap of your entire space, showing exactly where people are concentrated, where flow bottlenecks are forming, and which areas are approaching capacity limits.

The system calculates density at a granular level, measuring people per square metre across defined zones. You set capacity thresholds for each zone, and the system alerts when those limits are approached or breached. It also tracks flow rates through entrances, exits, and corridors, identifying when throughput drops below safe levels.

Evacuation readiness is calculated continuously. The system models how long it would take to clear each zone based on current density, exit capacity, and flow patterns. If an emergency occurs, operators have an instant picture of where the highest-risk concentrations are and which exits have available capacity.

Why It Matters

The real-world impact

Crowd crushes and overcrowding incidents are preventable with the right information. The problem is that by the time staff notice dangerous density levels, movement is already restricted and the situation is hard to control.

Archangel provides the early warning that manual observation cannot. Venue operators can manage capacity proactively, opening additional areas or slowing entry before dangerous thresholds are reached. For events that fall under Martyn's Law, this provides documented, continuous compliance with capacity management requirements.

Capabilities

What it detects

Purpose-built detection models tuned for real-world conditions and operational environments.

Real-Time Density Mapping

Generates live heatmaps showing people concentration across every zone. Operators see exactly where crowds are building before they become dangerous.

Capacity Threshold Alerts

Custom thresholds for each zone trigger tiered alerts. Amber warnings at 80% capacity give staff time to act before red alerts at 95%.

Flow Rate Analysis

Tracks the speed and direction of crowd movement through entrances, exits, and corridors, identifying bottlenecks and restricted flow patterns.

Evacuation Readiness Scoring

Continuously calculates estimated clearance times for every zone based on current occupancy and exit capacity, giving operators an instant emergency picture.
