Park’s Lighting Responds to Noise to Beat Vandals

The lighting in a public park in Austria has been fitted with acoustic sensors to respond to noise. The innovative installation at the People’s Garden in Graz is designed to respond to anti-social behavior at night and increase feelings of safety and security. Six outdoor luminaires, equipped with a combination of motion detectors and noise sensors, are dimmed to 20 per cent as standard. But as soon as one of the four fittings with a motion detector senses any kind of movement, the output is raised immediately to 50 per cent. If one of the two acoustic sensors picks up any noise, the fittings illuminate the area to 100 per cent. The lights – Supersystem luminaires from Zumtobel – may become even more intelligent in the future, as the Graz authorities have the option to control the lighting centrally and remotely using dedicated software.
