etc., while Sleeping, Recuperating, Nesting, Calving, etc. Also suitable
for discreet observation of Porches, Entrances, Driveways, etc.
Suitable
for average to zero illumination levels in
Homes, Shops, Showrooms, Offices, Warehouses, sheltered, shaded & evenly
lit outdoor use under eaves, etc.

Main Features
Infrared Light Emitting Diodes (LED) with
controller to optimise performance at zero lux (in total darkness).
Specially developed 5 element Lens constructed
from glass with 131 layer optical coating provides good focus with Visible,
Mixed and Infrared light sources. With this Lens images are clear in darkness
with infrared illumination. This kind of performance was previously impossible
due to the different focus points of visible and infrared light, ordinary lenses
(unless re-focussed) will usually produce images that are blurred and vague.
Solid State IR Cut Filter Switch, with day and
other mixed light sources IR Cut Filter is turned on to ensure infrared light
which is detrimental to white balance is blocked. As illumination falls infrared
LEDs gradually turn on and IR Cut Filter is turned off to allow infrared to
pass.
Colour will be reproduced when scenes are lit by
infrared illumination allowing identification of coloured lights such as red,
green or blue indicator lamps, traffic lights, neon signs, etc. This is not
possible with most ordinary Day / Night Cameras as the colour sub-carrier is
turned off to improve Signal to Noise Ratio. Using a special proprietary colour
rendering circuit MINI-COL-IR is able to leave the colour sub-carrier turned on.
Special cover glass to minimise/eliminate fog
build up on either inner or outer surface.
Other Features
~ 60 dB Signal to Noise Ratio, ~ 52 dB minimum
(ordinary cameras 40 ~ 48 dB).
120 + dB Smear Rejection Ratio (ordinary cameras
90 ~ 110 dB).
750 mV dynamic range (ordinary cameras ~ 450 mV).
Video System: PAL fully compatible with
Australian TV System.
Image Device: 542 (H) x 586 (V) 317
612 Pixel ¼" Inch Interline Transfer
LOW BLEMISH CCD
Sensor, due to the sensitive nature of the chip manufacturing process there may
be more imperfections in the photodiodes in this Special CCD Image Sensor than
in an ordinary sensor, click here
for more info.
Video Output: 1.14 V p-p Composite
Video 75 ohms, suit Australian TV, VCR, AV & Video inputs, BNC socket on ~ 30 cm
cable.
Horizontal Resolution: 460 + pixels
(this value is provided for comparative purposes only) Better than VHS * Near
Super-VHS resolution.
Minimum Illumination: ~ 1 lux @ F1.2
(this value is provided for comparative purposes only), 0 lux with LEDs 'ON'.
The Infrared LEDs illuminate ~ 80% of the Width-of-Vision and are effective up
to approximately 5 metres depending on the reflective characteristics of
subject.
Smear Rejection Ratio: 120 + dB, copes
with higher levels of illumination (Daylight) than ordinary (non AI Lens) type
cameras before smear becomes evident. Click
here for info about
Smear. See
GEM-II for pictures illustrating 'Smear'.
Dynamic Range: ~ 750 millivolts,
provides a greater correct exposure range between darkest and brightest areas
and therefore better colour rendition. Ordinary
cameras normally have a
3:1 linear dynamic range that is limited by the saturation of Cyan Magenta
Yellow and Green filter at 450 mV and a minimum signal level of 150 mV (450 mV :
150 mV = 3:1 ). This camera with 3rd generation DSP, special CCD and special RGB
mosaic conversion algorithm achieves 750 mV saturation on Red colour and minimum
signal level of 100 mV = 7:1 dynamic range (750 mV : 100 mV) 2.5 times better
than ordinary cameras. See
GEM-II for pictures illustrating 'Dynamic Range'.
Light Emitting Diodes: Twelve ~ 840 nm
wavelength Infrared, these produce a dull Red visible glow. Automatic Light
Sensor switches LEDs On/Off depending on light level.
Spectral Sensitivity: ~ 400 to ~
1000 nm, controlled via Solid-State IR CUT Switch.
Automatic Electronic Shutter (AES):
1/50 to 1/120 000 second, 20 milliseconds to 8.33 microseconds, additional
information
here.
Automatic Gain Control: Yes.
White Balance: Automatic / Automatic
Tracking, zero Colour Rolling (with fluorescent lamps).
Spectral Response:

3200º ~ 10000º K.
Signal to Noise ratio: Typically 60
dB, minimum 52 dB, measured with AGC off.

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.
