Motion and presence detectors from Feller are true multi-talents. On the one hand, they stand for safety, e.g. in underground garages or outside areas of buildings. On the other hand, they offer a lot of convenience thanks to the automatic control of light sources. Not only can the light be switched on and off, but its intensity can also be regulated automatically. And they ensure that light only burns for as long as it is actually needed, thus helping to save energy.
