SafeHaus pairs Ouster Gemini with a decade of crowd intelligence to proactively keep events safer
SafeHaus uses Ouster Gemini to turn entire festival sites into a single, continuous 3D map — delivering square-meter-level crowd density tracking, sub-100 ms safety alerts, and privacy-first monitoring at the world's largest live events.
The Critical Need for Modern Crowd Safety
Music festivals, sporting events, and cultural gatherings have become pinnacle intersections of exhibition and technology. They have become unforgettable experiences and are attended en masse now more than ever. However, as crowd sizes grow, so do the risks.
Tragic incidents at global events have highlighted the critical need for innovative solutions to prevent crowd "crush" scenarios and introduce general safety monitoring. Traditional methods of monitoring are often reactive rather than proactive. SafeHaus is redefining this landscape with a crowd monitoring software solution designed to manage flow, optimize layouts, and prevent bottlenecks, ensuring that festivals remain a celebration rather than a safety hazard.
The Challenge: Reliability and Visibility in Complex Environments
Event organizers face significant hurdles when trying to monitor tens of thousands of people simultaneously. Here, legacy and camera-based methods face distinct limitations:
Environmental Obstructions: Festivals are dynamic environments often filled with smoke, dust, fog, and low-light conditions, rendering traditional video surveillance unreliable or useless.
High-Density Blind Spots: In scenarios with densities greater than 3 people per square meter, video analytics struggle to separate individuals, leading to inaccurate data just when it is needed most.
Privacy Concerns: In an era of heightened digital surveillance, capturing video footage of faces poses significant privacy risks for attendees.
Latency Issues: Emergency response requires split-second decisions. Video processing often suffers from variable latency, failing to deliver the <100ms response time required for critical alerts.

The Solution: Real-Time 3D lidar perception
Safe Haus developed a comprehensive crowd monitoring solution that moves beyond the limitations of 2D video. By utilizing Ouster’s high-resolution digital lidar, Safe Haus achieves square-meter-level crowd density tracking. This level of precision is essential for the immediate detection of potential safety hazards, including dangerous crowd accumulation patterns that lead to crowd crush scenarios. Unlike cameras, Ouster’s lidar sensors create complete 3D venue maps that operate reliably in any lighting condition, respecting privacy by focusing on movement and density rather than capturing identifiable biometric data.
To ensure the solution works in the chaotic reality of a music festival, Safe Haus selected Ouster for its superior sensor capabilities. Ouster’s large Field of View (FOV) and extensive range coverage allow for the monitoring of vast areas with fewer sensors. Crucially, the sensors offer great reliability in varying environmental conditions, penetrating dust, fog, and darkness where cameras would fail. This ensures that from the main stage to the concession lines, organizers have a continuous, accurate view of the ground truth.
Organizers now have the confidence to make real-time decisions during live events, and the historical data captured by Gemini helps SafeHaus improve future event layouts and ensure emergency services remain readily accessible.
The result is a crowd safety solution venue operators can scale to match the size of any event, ensuring a safer, smoother experience for every attendee.
Results & Partnership Summary: Data-Driven Safety
Deploying the Safe Haus solution powered by Ouster has fundamentally shifted how events are managed. Real-world data demonstrates that lidar technology provides superior performance for applications requiring high accuracy and environmental resilience. The system maintains >95% accuracy even in high-density conditions and ensures 99.5% uptime, providing organizers with the confidence to make real-time decisions. This has led to safer environments, where data analysis helps improve future event layouts and ensures emergency services are readily accessible.
The partnership with Ouster has been pivotal to this success. The Safe Haus team selected the hardware specifically for its robust performance. By integrating Ouster’s rugged sensors with Safe Haus’s advanced analytics, venue operators can now match their technology choice to the scale of their venue, ensuring a safer, smoother experience for all attendees.
