The locations are determined using visible light signals and dead reckoning information recorded at different moments. The presence detection information indicates presence detected using presence sensor devices (31, 32) at the different moments. The system is further configured to obtain sensor locations and sensor fields of view, determine sensor orientations based on the locations of the mobile device, the sensor locations and the presence detection information, and determine a sensor coverage area (61, 62), comprising gaps in the sensor coverage area, based on the sensor locations, the sensor orientations and the sensor fields of view. The system is also configured to determine one or more parameters for presence detection based on the gaps in the sensor coverage area and output the parameters or a presence detection result which has been determined using the parameters.
