3.9 Notes for usages of integrated White Light LEDs

The LED range is heavily dependent on the ambient conditions. If the surroundings in
the camera's field of view are poorly reflective, or if there is no object within the
maximum illumination range, the brightness of the video image may be too low at night.
This results in poor usability of the video image.
Furthermore, when installing the camera, make sure that there are no objects in the
immediate vicinity (e.g. gutter or wall) around the camera's field of view. In this case,
reflections of the LED light from these objects can occur. The effects in the video image
would be ring-shaped dissolves in the opposite direction of the object.
The LED range can be reduced by strongly absorbing surfaces (e.g. asphalt).
