Swearing, destroying equipment or even physical attacks. What used to be rather rare is now experienced by hospitals or emergency services in hundreds of cases a year. Some establishments therefore organise self-defence courses, while others provide security buttons for paramedics. The need to contact the police is no exception.

Sound Event Detector (SED) installation targets
▶️ Increasing the protection of soft targets in hospitals.
▶️ Immediate summoning of security in case of problems.
▶️ Increase the efficiency of the hospital operations centre.
▶️ Analysis of the places where problems occur most often.
Soft Targets Protection Concept 2017 – 2020
Although the Soft Targets Protection Concept 2017 – 2020 was approved in 2017, it was not until two years later that the ministries started to provide financial support for non-investment programmes.
They were mainly focused on the development of security analyses and documentation to enhance the protection of soft targets, the organisation of training, seminars and exercises, which were then to be followed by concrete investments from 2021 onwards.
All of this was supposed to lead to the creation of a national comprehensive soft target protection system, but this has not yet happened.
Problem solving
| 01 Procedure for solving the order | Initial analysis to understand the problem sites, identifying a site for initial installation. |
| 02 What a concrete solution | Inspection of the site selected for POC implementation, evaluation of coverage options, installation and alternative solutions. |
| 03 Reasons for the chosen solution | There is no alternative tested solution on the market that allows the system to react in real time to sudden events such as aggressive behaviour, shouting, glass breaking, shooting and others based on sound analysis, only SED has these unique features, while maintaining GDPR. |
| 04 Solving problems | Integration into the customer’s VMS – Avigilon, the original version could not work with ONVIF events, now fully compatible, in addition, the integration of video and audio streaming has been successful, where Avigilon takes the SED as a full-fledged camera and allows to set the interconnection with the original camera system. |
Design solutions in time
Specific locations for installation of Sound Event Detector (SED) were selected with the customer FN Plzeň.
Carrying out a coverage test at the installation sites. Practical demonstrations of SED. Efficiency test. Testing of 3 SED devices in the premises of the FN Pilsen.
Evaluation of test results with 3 SED devices.
Order 10 SED devices – 6 × indoor versions of SED devices, 4 × outdoor versions of SED devices.
Installation of 10 SED devices.
Evaluation of the effectiveness of SED devices.
Coverage study
Coverage design procedure
- Location of installation of SED devices: the Universtiy Hospital Plzeň.
- The following specific locations were selected for sound event detection: outpatient treatment – waiting rooms, surgery – waiting rooms, buildings belonging to critical infrastructure – wastewater treatment plant, locations with inadequate building intrusion protection, and private employee parking – due to physical assault or vandalism.
- The proposed locations were consulted with the customer, including the requirements for the detection range and the design of the number of SED devices to cover the selected locations.
- A total of 10 SED devices were quantified for FN Pilsen.
Map of coverage
Results of the case study
- Cost of implementation of 10 Sound Event Detectors (SED) devices: 250 000 CZK (without VAT).
- The system is fully integrated into the VMS in the operating centre of the Universtiy Hospital Pilsen. The SED solution is already in full use.
- The customer is considering the purchase of additional equipment as well as the use of SEDs for drone protection capabilities.
- The new SED functionality for drone detection is planned for the end of 2023.
