Steinel’s Control Pro system of presence detectors for controlling lighting have square-shaped detection characteristics that are said to be better suited to the layout of rooms such as offices and conference areas than the round attributes used by conventional presence detectors. According to Steinel, ‘Never before has it been possible to cover offices and commercial areas with presence detectors without overlaps or leaving gaps. Using Control Pro, zones can be planned perfectly, with reliable detection at every point of the room and up to 4800 switching zones.’
