Abstract: A camera is provided that comprises an image sensor for detecting image data from a detection region and a reception optics arranged in front of the image sensor, a focus adjustment unit having a thread for changing the position of focus of the reception optics by way of a rotary movement and a front screen. In this connection the reception optics has a front region having an inner contour that is accessible via the front screen in order to rotate the reception optics from the outside in the thread and to thus adjust the focus.

Abstract: A camera is provided that comprises an image sensor for detecting image data from a detection zone, an illumination unit having at least one light source for illuminating the detection zone, and a front screen. In this respect, a lateral deflection element is provided that is associated with the light source, that is arranged in the camera protected by the front screen, and that has a diffusely scattering surface or a reflective surface to generate a diffuse illumination or a dark field illumination in the detection zone.
