Real Time Analysis, Reporting and Localization

with Smart Acoustic Sensors

The progress of humankind has inevitably brought an increasing proportion of an increasing population to live in urban environments, with its attendant risk to public safety and to the environment.

Real-time analysis, reporting, and localization with smart acoustic sensors make Securaxis’ RTExD an ideal solution for monitoring health of infrastructures such as highways, bridges, tunnels, dams, pipes, wind turbines and more; or to be used for traffic management and smart city safety; allowing to save time, money and resources while keeping people safer.

In parallel, measuring the impact of infrastructures on ecosystems is essential but time consuming and expensive. All associated sounds can be detected, identified and monitored. Therefore intelligent acoustic monitoring provides an innovative, low-cost but efficient answer to monitor wildlife.

Securaxis’ acoustic sensors add the missing component to existing smart solutions

Sound Monitoring.

The Securaxis Real-Time Event Detector (RTExD) is a smart acoustic sensor connected to a wireless network that can analyze sounds in an urban or noisy environment and then classify, locate, and report them accurately. RTExD turns noise into data that informs action.

Acoustic event detection technology opens up many areas of application. The RTExD information model is based on a data monitoring and acquisition (SCADA) system developed at CERN, designed to archive information and provide data visualization, alarms, and other functions.



It has been demonstrated that sound is an efficient indicator for monitoring ecosystem biodiversity.

Wildlife acoustic monitoring with RTExD can provide information such as species, habits, quality of life and habitat condition. It also helps determine its interaction with human habitat and human built infrastructures.

This would fulfill an important part of the environmental impact studies that are required before and after any major construction project.



RTExD allows for the counting and categorization of vehicles, as well as determining their direction.

It also helps to combat traffic-related noise pollution.

RTExD is a much cheaper solution and easier to implement than video cameras. RTExD can be easily implemented with any system, new or existing, because hybridization with other IoT sensors, such as air quality sensors, is the future of efficient smart cities.



RTExD sensors placed on and integrated into infrastructure such as tunnels, bridges, roads, and dams can be used to monitor their health by capturing the sounds emitted when material failures occur. Acoustic sensors detect and locate failures before an infrastructure breakdown.



Capable of detecting and analyzing all types of sounds associated with violence or insecurity such as gunshots, explosions, screaming, breaking glass, roaring crowd, RTExD is ideal for improving safety, security and emergency response by monitoring such specific sounds.

RTExD is designed to be integrated into the environment where video camera installations are not needed, or to be combined with cameras.


The Securaxis solution can easily be applied as a stand-alone system or integrated into any new or existing system, hybridization being the next step for IoT sensors.

According to “Sensors for IoT” (BCC Research, Sep. 18), “A new technology shaped by new requirements for IoT applications will create new product categories or give new life to existing products through adaptations…These new requirements include user privacy protection…Techniques such as hybridization will come into play to drive advances.”
