The surveillance device has a camera (10), e.g. a CCD or CMOS camera, mounted behind a mirror glass (1) provided with a mirror layer (5) for reflecting light in the visible wavelength spectrum, so that the camera is not visible from the front of the mirror glass. The mirror layer can be provided by an interference reflection layer, e.g. a chrome mirror layer or a titanium-chrome mirror layer. |
