Basic Starlight Features

Dahua’s Basic Starlight technology offers good low-light performance for applications with a minimum illumination of 0.008 to 0.009 lux. This option offers a more affordable price for low-light technology that is ideal for moderately dark areas.

Dahua’s flagship low-light standard, Enhanced Starlight technology produces clear images in near-dark conditions. With a minimum illumination range between 0.005 lux to 0.007 lux, details stay in color longer for enhanced video quality.

Starlight+

Dahua’s Starlight+ technology provides the best low-light performance requiring a minimum illumination of only 0.004 lux. Cameras with this technology use a large sensor, smart imaging algorithms and a set of optical features to balance light throughout the scene, resulting in rich colors in the dark with no noise or colour distortion. The lens is a key component of any security camera and one that directly effects the quality of the image.

Night Color Technology

Night Colour technology works differently than the technology used in Starlight cameras. Cameras that incorporate Night Colour technology use a high-performance sensor and ISP, and an achromatic large aperture lens, to produce crisp, clear colour images in low-light environments. This light-sensitive technology allows the camera to remain in Colour Mode and to capture more available light to reproduce colour images with superior detail and contrast in applications with at least 1 lux of ambient or artificial light.

Unlike Starlight Technology, Night Colour Technology does not utilize an IR Cut filter. This results in an image that remains in color 24/7 without switching to black/white. Night color also utilizes an Achromatic lens. This type of lens is a combination of concave and convex pieces of glass that focuses the different color wavelengths of light into a single plane. An Achromatic lens eliminates the problematic chromatic aberrations and is the most cost-efficient means for good polychromatic imaging. Dahua Night Colour cameras also have an f-stop of 1.0 on 2MP models or 1.2 on the 4MP models to deliver crisper and clearer full-color images in all environments with at least 1 lux of ambient light.

Similar to Starlight Technology, Dahua’s Night Color Technology utilizes Back-illuminated CMOS technology.  STARVIS™ sensors offer a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. A back-illuminated structure increases the amount of light that enters each pixel and moves the sensor’s photosensitive surface closer to the light. It also utilizes Smart Image Signal Processing to convert an image into digital form while performing operations that enhance the image or extracts useful information. ISP identifies and corrects imperfections caused by the lens, colour filter, or sensor.

White-light Night Colour Technology

Dahua’s White-light cameras utilize white-light LEDs to offer full-colour images in total darkness, as well as an effective visual deterrent, when you need it most. This technology provides smart illumination where the camera automatically activates the white-light illuminators at low lux levels, adjusting exposure time and LED intensity to prevent overexposing the image.

Similar to Starlight Technology and other Night Colour models, White-light Night Colour utilizes Back-illuminated CMOS technology. STARVIS™ sensors offer a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. A back-illuminated structure increases the amount of light that enters each pixel and moves the sensor’s photosensitive surface closer to the light. It also utilizes Smart Image Signal Processing to convert an image into digital form while performing operations that enhance the image or extracts useful information.
