DW's revolutionary Star-Light Plus™ technology explained
Star-Light Plus technology delivers high-resolution, full-color video with reduced ghosting and motion blur in near-total darkness. In extreme low light environments, where other cameras would switch to B/W or require external illumination, Star-Light Plus cameras remain in color mode, showing crucial details, resulting in superb image quality. MEGApix® IP cameras and Universal HD over Coax® cameras with Star-Light Plus technology are ideal for applications demanding low-light video surveillance in color, such as parking lots, city surveillance, campuses and construction sites.
Key Technologies
Color in darkness technology
Star-Light Plus technology produces a high picture quality in both low visible-light and near-total darkness infrared environments.
Star-Light Plus™ monochrome image
in near darkness.
Star-Light Plus™ also delivers color image details in near darkness.
Color video for accurate identification in extremely low light
In near-total darkness environments, where conventional day/night cameras switch to B/W video, IP and UHDoC cameras with Star-Light Plus technology can remain in full color and continue to deliver important identification of people, vehicles, and vehicle incidents with no detail loss. Operators can quickly review color footage and identify a suspect's clothing or a car's color for rapid intervention and accurate identification.
Reduce digital noise and motion blur
Star-Light Plus technology increases the image clarity of objects in motion with shorter exposure times. The Star-Light Plus sensors enable a shorter shutter speed even in low light, reducing motion blur's side effect in moving objects in low light. This provides smooth movement and details and the ability to freeze on single frames without losing details from ghosting or motion blur.
Increase the depth of field
Low light applications require a larger lens aperture to capture more light during exposure, leading to a shorter depth of field, meaning a shorter part of the scene can be in focus simultaneously. Star-Light Plus cameras can produce high-quality color images with shorter exposure times, which means the cameras can be paired with smaller lens apertures, resulting in increased depth of field in the image.
Intelligent bitrate control with no loss of quality
Star-Light Plus technology combines extra-sensitive image processors, high-quality lenses, fine-tuned digital image processing and intelligent bitrate control to preserve image details and produce video relatively low bitrate to reduce storage costs.
Back-illuminated sensor (BIS) technology
Backside-illumination technology flips the position of the pixels and the circuitry to collect the light from the sensor's backside. This improves light capture from 60% to over 90%.
World-class light absorption
DW's Star-Light Plus technology enables smaller pixels and sensor size for cost efficiency, without sacrificing performance and video quality.
Capture images in near-total darkness better than the human eye
Star-Light Plus technology captures full-color images in near-total darkness, even better than the human eye. A camera with Star-Light Plus technology can produce. This is particularly important when footage is required for forensic investigation, where true colors and details increase the chances of proper identification and evidence collection.
Understanding Lux
Light intensity represents the light intensity in a scene, measured in lux (lx), with one lux = one lumen per square meter. Light measurements are a good tool for estimating the light conditions needed for different installations. DW's Star-Light Plus cameras can deliver color images in as low as 0.04 lux.
| Light Intensity | Environment |
|---|---|
| 0.01 | Clear night with a quarter moon |
| 0.27 lux | Clear night with a full moon |
| 1 lux | Dusk |
| 10 lux | Twilight |
| 300-500 lux | Office light |
| 10,000 lux | Full daylight |
| 100,000 lux | Stribg sunlight |
