Infrared light emitting diode night vision cameras offered by Allthings Sales & Services

Supplier News

Allthings Sales & Services  offers day night colour infrared light emitting diode, night vision cameras. Colour day night CCTV security cameras are available with integral infrared light emitting diodes and these create images even when noticeable illumination is zero.

At standard levels of illumination these Colour day night CCTV security cameras create colour images depending on their sensitivity at low levels of illumination and in entire darkness the image is monochrome.

Colour day night CCTV security cameras usually have a comparatively fixed iris lens and a high sensitivity image sensor. Therefore in high illumination levels images get overexposed. An exception is MINI-COL-IR which has a unique, wide dynamic range that allows it to manage higher levels of illumination than normal CCTV Cameras.

Normal colour CCTV Cameras are comparatively insensible to infrared because of an IR CUT filter which is present between the image sensor and the lens. Infrared radiation is excluded by this filter with a wavelength greater than ~ 700 nm that would otherwise unfavourably affect colour rendition, white balance and image sharpness.

Day night colour CCTV cameras are responsive to Infrared as they either utilise a special NOTCH IR CUT filter or they do not have an IR CUT filter that excludes the wavelengths most injurious to the quality of colour (720 ~ 830 nm) from reaching the image sensor.
