A method for configuring a lighting system including one or more sensors for controlling one or more lighting units for providing illumination of an area. The method allows a target area to be determined for a particular sensing function, and then determines suitable sensor locations based on a mapping derived from an image of the area in question. The target area can be determined based on recognition of relevant objects such as doors and window for example. The sensor location or locations may be selected from existing sensor locations which may be integrated with a luminaire, or new sensor locations may be proposed.
