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, Security lenses.

Lens: Board Type 4.3 mm Focal Length, there are
no Accessory Lenses for this Camera,

System: 2 : 1 Interlace PAL 50 Hz
vertical, 15 625 Hz horizontal.
Synchronisation: Internal.
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.

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 Gain Control: Yes.
White Balance: Automatic / Automatic
