ground level offered by a device and/or devices other than mirrors. This may be limited by the relevant detection distance corresponding to the critical object.

              2.1.10. "Detection distance" means the distance measured from the centre of the lens of the camera to the point at which a critical object can just be perceived (as defined by the critical perception).

              2.1.11. "Visual spectrum" means light with a wavelength within the range of the perceptual limits of the human eyes: 380‑780 nm.

              2.1.12. "Smear" is a bright line displayed on the monitor while sun light or light from other bright light sources is directly hitting into the lens of the camera.

              2.1.13. Mirror and CMS dual function system" means a CMS of Class I in which a monitor complying with this regulation is placed behind a semi-transparent mirror complying with this regulation. The monitor is visible in the CMS mode.

              2.2. "Type of device for indirect vision" means devices that do not differ on the following essential characteristics:

                  (a) Design of the device inclusive, if pertinent, the attachment to the bodywork;

                  (b) In the case of mirrors, the class, the shape, the dimensions and radius of curvature of the mirror's reflecting surface;

                  (c) In the case of camera-monitor systems, the class, the field of view, the magnification and resolution.

              2.3. "Surveillance camera-monitor-recording device" means a camera and either a monitor or recording equipment other than the camera-monitor system defined in paragraph 2.1.2. above which can be fitted to the inside or outside of the vehicle in order to provide fields of vision other than those specified in paragraph 15.2.4. of this Regulation or to provide a security system within or around the vehicle.

              2.4. "Class of device for indirect vision" means all devices having one or more common characteristics or functions. They are classified as follows:

              2.4.1. Class I: "Rear-view device", giving the field of vision defined in paragraph 15.2.4.1.

              2.4.2. Class II and III: "Main rear-view device", giving the fields of vision defined in paragraphs 15.2.4.2. and 15.2.4.3.

              2.4.3. Class IV: "Wide-angle view device", giving the field of vision defined in paragraph 15.2.4.4.

              2.4.4. Class V: "Close-proximity view device", giving the field of vision defined in paragraph 15.2.4.5.

              2.4.5. Class VI: "Front-view device", giving the field of vision defined in paragraph 15.2.4.6.

              2.4.6. Class VII: Main rear-view mirrors intended for L category vehicles with bodywork giving the field of vision defined in paragraph 15.2.4.7.

              2.5.  "Point light source detection factor - PLSDF" means the level of distinctness of a pair of point light sources, based on luminance intensities and horizontal and vertical dimension of the rendition on the monitor.

              2.6.  "Point light source contrast factor - PLSCF" means the level of
