Zusammenfassung:Camera device 1 for taking at least one image of a scene in front of the camera device 1, the camera device 1 comprising: a sensor-camera 2 with a main beam path, whereby the sensor-camera 2 comprises a sensor 3, an IR filter 4 and an objective 5, whereby the IR filter 4 is arranged between the objective 5 and the sensor 3, whereby light with a wavelength smaller than a cut-off range passes the IR filter 4 into the sensor 3 and light with a wavelength larger than the cut-off range is reflected by the IR filter 4 and, whereby the main beam path is from the objective 5 into the sensor 3, whereby the objective 5 comprises a final optical element 7, whereby the final optical element 7 is the optical element next to the IR filter 4, whereby the IR filter 4 is tilted by a tilting angle, so that most of the reflected light or all of the reflected light is guided away from the final optical element 7.
