In absolute darkness, the internal infrared illumination can only be used up to a maximum
object distance of 2.0 m. In addition, the quality of the image is strongly influenced by the
resulting reflections and the object to be observed is no longer visible.
The image quality increases as soon as an external infrared light source is used.
When illuminated by external infrared light, the distance to be observed is more than
30.0m and the image has no noticeable loss of quality due to the illumination.
In absolute darkness, it is advisable to use an external infrared light source.
