Abstract

The passive IR detector has at least one IR sensor (20) and a number of optical lenses (12-18), each directing light from one or more fields of view (34-38) onto the IR sensor. A movable cover (19) is displaced between at least 2 different positions, for allowing light from different fields of view to be received by the IR sensor, e.g. in dependence on the mounting position of the detector.
