The effective IR range will depend on the installation location. If there
are surfaces that absorb light or no objects that reflect IR light in the
field of view, the IR range will be reduced and/or the video image will
be too dark. Reflective objects in the immediate vicinity of the camera
(e.g. roof gutter or wall) may also result in the reflection of IR light,
which can disturb the image.
