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.

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 for focus shift between Visible and Infrared)

The IDEAL Day / Night Infrared Sensitive Colour CCTV Camera utilises a Lens with an Automatic Iris to cope with high illumination levels - has a large aperture (low 'F' number) to maximise light transmission and is corrected for Infrared:Visible focus-shift, it also utilises a Traditional IR CUT Filter when illumination levels are adequate for Colour and REMOVES the IR CUT Filter when levels are low our Maxi Cameras have these features and are recommended for OPTIMUM results

BETTER SOLUTION: AutoCam-dn - DomePTZ-dn2 - DomePTZ-dn3 have Automatic-Focus to ensure crisp images regardless of illumination source.

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.

"See-in-the-Dark" Infrared capability using a notch (or no) IR-CUT Filter is a trade-off that adversely affects Colour rendition in "Infrared Rich" environments.
