Dahua TechMonth: Seeing in the dark with Dahua Full-color technology

Dahua TechMonth: Seeing in the dark with Dahua Full-color technology
Introduced in 2020, the Dahua Full-color technology has evolved from Starlight technology, Full-color, to Full-color 2.0 and the future Full-color infinity.
Inadequate availability of light is one of the major challenges of every monitoring system. Images taken under such lighting condition are often not clear, have detail loss, and even contain noise, making it difficult to detect or trace back targets in case of an event.
 
Over the years, improvements in low-light technologies have significantly progressed, leading to a new era of digital cameras that can perform well under low-light environments. In fact, according to the report made by International Data Corporation (IDC), sales for network cameras without low-light technology are expected to slow down over the next few years due to the increased adoption of cameras with low-light sensitivity.
 
However, traditional low-light cameras that claim to capture clear color images even at night often come with a heap of hitches, including light pollution due excessive use of supplementary white light, low resolution, poor image processing capability… and the list goes on.
 
Also, specifying a security camera for environments under low-light conditions isn’t a one-size-fits-all solution. Specifications alone do not define the best network camera when it comes to low light performance. One optimized solution might not be the best fit for other application scenarios. Therefore, the camera should be able to intelligently adapt to various types of scenarios in order to provide round-the-clock monitoring.
 
The Dahua Full-color cameras were developed to address these demanding monitoring challenges. Introduced in 2020, the Dahua Full-color technology has evolved from Starlight technology, Full-color, to Full-color 2.0 and the future Full-color ∞ (infinity). With remarkable offerings such as dual lens, vari-focal lens, 4K resolution, and AI features, this technology offers a wide-range of products and solutions that can effectively solve the arduous monitoring pain points of end-users and provide clear and vivid images of the monitored scene 24/7.
 
Moreover, the Dahua Full-color is more than just a low-light environment technology. It offers a great deal of specs that allows it to adapt to different types of scenarios. To give you more insights into this amazing technology, here are some cool features that make Dahua Full-color extra special:
 

F1.0 super large aperture

 

The aperture is used to control the amount of light that passes through the lens and into the body of the photosensitive surface of the camera. The Dahua Full-color cameras adopt F1.0 super large aperture lens that collects 2.5 times amount of light compared to the typical F1.6 aperture lens. As it receives more light, the brighter the image output it creates.
 

High performance sensor

 

The sensor used in a camera is very important. The more light each individual pixel of a sensor receives, the better the response and sensitivity. In a nutshell: the bigger the pixel, the better the low-light performance of the camera is.
 
The current Full-color 2.0 cameras are primarily equipped with 1/1.8’’ image sensor that offers 30 percent more photosensitivity than traditional sensors in the market. What’s more, the Full-color 4K IPCs even have 1/1.2” super large sensors that provide 110% pixel size increase compared with the 1/1.8” image sensor.
 

Warm light

 

As advancement in modern devices develops at a rapid pace, potential effects of the blue light content within display devices and lighting has become a subject of particular interest and concern. Various laws and regulations regarding this matter were established to promote safe lighting and avoid “blue light hazard.”
 
Instead of the conventional white light, the Dahua Full-color cameras use warm light with blue light weighted radiance of 40 percent below the European Union Standards. This means that the supplementary warm light has lesser effect on the human eyes, and relatively helps reduce light pollution in the monitored area.
 

AI-based advanced image processing
 


Dahua Full-color utilizes AI-based Image Signal Processing (ISP) to better improve its image output in terms of noise, color, sharpness, and so on. The capability of Full-color technology to capture color details in time and space comes from its powerful hardware, advanced image processing algorithms, and integration with other intelligent functions, leading to a “1+1=∞” breakthrough of infinite possibilities.
