Day Night Colour Infrared Light Emitting Diode (Night Vision) Cameras
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.
