SED: Sound detection of graffiti vandalism

August 18, 2023

Houses, public buildings, national monuments, park benches, trains, or any other tangible property are increasingly facing destruction in the form of graffiti spraying. This act not only damages property, but also disrupts the well-being and aesthetics of the urban space.

Revolutionary sound technology brings a light at the end of the tunnel – the Sound Event Detector (SED), a revolutionary tool that can identify graffiti sprayers using sound detection.

Sound Event Detector (SED): What is it and how does it work?

The SED is an innovative device designed to capture specific sound signals in real time. This technology is set up to identify the sounds associated with graffiti spraying – the sound of the spray. Once the SED picks up the characteristic sounds of spray, it immediately sends an alert to the operator operating the camera system, who dispatches security forces to the site.

Revolution in the fight against vandalism

SED marks a turning point in efforts to protect property from vandalism. Traditional methods of monitoring and detecting vandalism often fail, giving vandals the upper hand. But thanks to SED’s audio detection, the situation is changing. This technology is able to quickly and accurately identify acts of spray graffiti and provide a realistic tool for immediate action.

Catching a vandal: with sound and image

We now offer the SED sound detector with built-in camera. This camera version of the SED is suitable for places where the necessary infrastructure for camera points cannot be built. At the same time, the SED version with camera is many times cheaper than investing in camera points. You can read more about the camera version in the Product updates section of our website.
