Deployment of acoustic detection at Czech universities shows how dangerous situations can be identified early in a campus environment and how the orientation of security teams during dynamic incidents can be significantly improved.
Quick Facts:
Location: University campuses in the Czech Republic
Scenarios: Simulated crisis situations in an open university environment
Detected events: Gunshots, aggressive vocal expressions, shouting, glass breaking
Technology: Sound Event Detector (SED) by JALUD
Installation: More than 130 detection sensors deployed across university campuses
Context: Security in an Open Campus Environment
University campuses combine open spaces, park areas, pedestrian pathways, and large buildings. In crisis situations, the rapid identification of an incident and its precise localization play a crucial role. Traditional reporting methods often rely on human response, which can be delayed or inaccurate.
Acoustic detection addresses this problem by automatically capturing incidents in real time.
Course of the Test
As part of the test at the University of West Bohemia, controlled simulations were carried out involving:
gunshots
verbal aggression
shouting
glass breaking
During the test, a participant moved through different parts of the campus, which made it possible to verify the system’s behavior in a dynamic scenario. The detection network recorded individual events without delay and displayed them on the campus map.
Results That Cannot Be Overlooked
During the test, the acoustic detection system:
- reliably detected all simulated types of events,
- precisely localized the sound source on the campus map,
- created a timeline of incidents without delay,
- enabled the reconstruction of the participant’s movement using map outputs and heatmaps.
The system repeatedly provided the first information about an incident automatically, without the need for human intervention. The detections followed a logical sequence of activations based on the distance of the sensors from the source and clearly reflected the person’s actual movement across the campus.
Why It Matters
In university environments, security often relies on witnesses, emergency buttons, or camera surveillance. However, these methods can fail due to stress, panic, or delayed reactions. Acoustic detection operates continuously and responds immediately. It provides security teams with the first precise information about the type of event, its location, and how the situation is evolving.
Early detection = better situational awareness = faster and more targeted response.
Technological Background of SED
SED – Sound Event Detector (JALUD Embedded s.r.o.)
- Detection of gunshots, aggressive vocal expressions, and glass breaking
- High accuracy in the classification of acoustic events
- Real-time map and heatmap outputs
- Integration with camera systems for visual verification
- Suitable for open campuses as well as multi-story buildings
Limitations and Further Development
The test confirmed that acoustic detection is most effective for incidents that produce a clear sound signature. The study also highlights the importance of combining multiple sensing layers (audio + video) and the need for further expansion of the detection network in large-scale campuses.
Conclusion
This case study confirms that the SED acoustic detection system by JALUD represents an effective tool for improving safety in university campuses.
The technology is ready to protect environments where thousands of people move every day and to provide security teams with clear, fast, and understandable data. Whether for universities, schools, or other public institutions—where rapid situational awareness and the right decision matter, acoustic detection has a solid place.
