Colour CCTV Day Night Cameras with inbuilt
Infrared Light Emitting Diodes
"See-in-the-Dark" and produce images when visible illumination is zero.
At average levels of illumination these Cameras
produce Colour images, depending on
their sensitivity (Lux) at low illumination levels and in total darkness the
image is Monochrome.
These Cameras generally have a relatively high
sensitivity image sensor and
Fixed Iris Lens
therefore under high illumination levels images will be overexposed for the
reasons outlined
here, an exception is
MINI-COL-IR which has a special Wide Dynamic Range allowing it to cope
with higher illumination levels than ordinary Cameras.
Ordinary CCTV Colour Cameras are relatively
insensitive to Infrared because they have an IR CUT Filter between the Lens
and Image Sensor, this filter excludes Infrared radiation with a wavelength
greater than ~ 700 nm that would otherwise adversely affect White Balance,
Colour Rendition and Image Sharpness.
Day / Night Colour CCTV Cameras are sensitive to
Infrared because they either do not have an IR CUT Filter or utilise a
special NOTCH IR CUT Filter that excludes the wavelengths most harmful to
colour quality (720 ~ 830 nm) from reaching the Image Sensor.
A Colour Camera that does not have an IR CUT
Filter usually has poor colour
rendition characterised by a Pink-Red
'tint' when the illumination is InfraRed rich, use of
a 'Notch' Filter helps however White Balance, Colour Rendition and Image
Sharpness are compromised for Infrared sensitivity. (Image
Sharpness can be restored by using a specially designed Lens that corrects
the focus shift between Visible and Infrared)
The IDEAL Day / Night Infrared Sensitive
Colour CCTV Camera would utilise an Automatic Iris
Lens to cope with high illumination levels and the Lens would also have
a large aperture (low 'F' number) to maximise light transmission when
illumination levels are low * it would also utilise a Traditional IR CUT
Filter when illumination levels are adequate for Colour and then REMOVE
the IR CUT Filter when levels are low
Dome-DayNite,
Maxi-DayNite,
Dome-D/NiteEx,
Maxi-D/NiteEx &
CCS-IRdnWD have these features and are recommended
for OPTIMUM results - the ULTIMATE SOLUTION is
AutoCam-dn or
DomePTZ-dn these also have Automatic-Focus to
ensure crisp images under all conditions.
Infrared rich light
sources include Daylight and most Filament type lamps including common Spot
lamps, Tungsten lamps, Halogen lamps, etc.
The majority of Light emitted from 'Cold' type
sources such as Fluorescent, Mercury Vapour, Sodium Vapour, etc., is
visible, these sources contain little Infrared energy.
SUMMARY:"See-in-the-Dark"
Infrared capability is a trade-off that affects
Colour Quality particularly in "Infrared Rich" environments.
