In the case of a detector unit (4, 5) for monitoring a room (1), particularly for switching on and off at least one light source (6, 9), the detector unit (4, 5) is a multizone detector for monitoring a plurality of zones (40, 41, 50, 51) of the room (1) and has at least one sensor element (42, 43, 52, 53) per zone (40, 41, 50, 51) to be monitored and at least one device (44, 54) for demarcating the sensing ranges of the sensor elements (42, 43, 52, 53) for the zones (40, 41, 50, 51) from one another. In the case of a detector system, said detector system comprises at least one such detector unit (4, 5) and at least one control unit (7). |
