Anybody also wanting to control lighting automatically indoors enters a fi eld that's capable of saving huge amounts of energy. Yet maximum demands must also be made on the sensors because they need to identify precisely and reliably whether people are present in the room even if they hardly move, let's say while sitting at work. A product that no longer notices school students quietly studying and switches the light 'OFF' shouldn't call itself a presence detector. Even one with a low detection resolution is unsuitable in our eyes. With perfected sensor technology as our foremost maxim, this catalogue now presents you with true presence detectors that can actually say they meet the most exacting of demands. At the same time being tailored to any room type and indoor control task.
