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).

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

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 m 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. CCTV smear 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.

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.
