Dahua TechMonth recap: An overview of the development of Dahua full-colour technology

Over the years, Dahua has continuously invested in the development and innovation of Full-colour technology to solve the monitoring challenges brought by low illumination.

In 2018, the company launched the Starlight and Starlight+ technologies which enable cameras to effectively capture colour details in low-light environments.

24/7 colour monitoring

Focusing on further improving low-light monitoring, Dahua officially released the Full-colour concept in 2020, realising 24/7 colour monitoring by introducing F1.0 super aperture, 1/1.8 '' high-performance sensor for large targets, and Dahua’s self-developed ISP 4.0 technology.

The colour information of key targets in the scene can be captured even at night, which can be used as evidence in case of an investigation or backtracking.

Dahua Full colour 2.0 technology

Dahua TechMonth showcases some of the integrations of Full-colour technology for customers and end users

In 2021, the company continued to upgrade its technology and launched the Dahua Full colour 2.0 technology. It further expanded the Full-colour “family” and integrated 4K, panoramic, zoom, and other technologies to facilitate the development of high-end products, provide a more comprehensive product system, and enhance low-light surveillance.

To elaborate more about this remarkable technology, Dahua TechMonth showcases some of the integrations of Full-colour technology that create more business value for customers and end users.

Recap of solutions

Following is a short recap of these amazing solutions:

• Full-colour + TiOC

The TiOC (three-in-one camera) has 3 main features: Smart Dual Illuminators, Active Deterrence, and AI. It can effectively warn off intruders with active deterrence, and notify users in time with real-time alarm, providing pro-active video surveillance to properties that require 24/7 security.

TiOC utilises Full-colour technology to capture colour footage in dark scenarios. Also, its smart exposure technology realises time-sharing control and prevents the interference of flashing red & blue light in the image. To see TiOC in action, check out this video.

• Full-colour + Panoramic

The Dahua Full-colour Dual Lens 180° Panoramic PTZ & IPC devices are equipped with dual sensors that deliver a 180-degree field of view. After the right and left lenses to capture an image, the camera calculates the feature values of the left and right images to avoid warping and pixel loss using standardised image correction technology.

The Dahua advanced pixel-level metadata fusion algorithm then enables seamless splicing of the image, resulting in a seamless 180° wide-angle image.

Panoramic IPC

The Panoramic IPC offers EPTZ that provides a panoramic image of the scene, as well as sub-images that focus on specific areas or targets.

For the panoramic PTZ camera, both panoramic and detailed views support AI functions and can be independently deployed in different directions to cover wider areas. 

• Full-colour + ZOOM

The motorised varifocal lens of the upgraded Dahua Full-colour 2.0 network cameras has approx. 5x optical zoom capability and auto-focus function, providing clear colour details of the monitored scene even after zooming in.

With its long-distance illumination capability, the camera can also capture a clear full-coluor image even from far distances.

• Full-colour + 4K

The Dahua Full-colour 4K camera delivers enhanced colour images and surveillance footage 24/7. It adopts a 1/1.2” image sensor (currently Dahua's best low-light IPC sensor) that provides a 110% pixel size increase compared to a common 8MP sensor.

Its F1.0 large aperture can capture more available light and the maximum light energy that the sensor can receive is increased by 2 times.

Success Case: Schwarze Berge Wildlife Park

Located in Rosengarten Germany, the Schwarze Berge (Black Mountains) Wildlife Park covers an area of about 50 hectares. It is home to nearly a thousand of animals from approximately 100 species grazing in Europe. The administration of the park was looking for a comprehensive camera system that can perform many tasks.

“We chose Dahua because it customised a complete solution to meet all our needs,” says Arne Vaubel, Managing Director of the Schwarze Berge (Black Mountains) Wildlife Park.

Full-colour and thermal imaging

In this project, a full series of innovative cameras equipped with key technologies"

“In this project, a full series of innovative cameras equipped with key technologies, such as Full-colour and thermal imaging are adopted."

"We are glad to see that through our cameras, the park can monitor the living environment and health status of wild animals at any moment without disturbing them, which also helps the park realise efficient operation and management,” explains Kai Wockenfuß, Pre-Sales Support Technical Engineer of Dahua Technology GmbH.

Fixed-focal Warm LED Bullet WizMind Network Camera

One notable Dahua camera deployed in the park is the 8MP Full-colour Fixed-focal Warm LED Bullet WizMind Network Camera. It is equipped with a high-performance sensor and large aperture lens, enabling it to capture clear colour images when it’s dark or during the night.

With its photosensitivity technology, the camera can capture more available light and display more colourful footage of the monitored scene, providing 24/7 monitoring of the wildlife in the park.

The future of Dahua Full-colour technology

With the success of Dahua Full-colour in the market, what does the future holds for this amazing technology?

For starters, minimising white light pollution is at the top of the list. Some cameras with full colour capabilities in the market still use white light, which can affect the human eye and cause severe light pollution in the monitored scene.

Touchless Full-colour cameras are one solution that Dahua has been exploring through its multi-spectrum algorithm. The Dahua Multi Spectrum Fusion technology extracts the details and brightness of the visible spectrum and infrared spectrum to make the fusion brightness close to the visible light brightness, which then enables the camera to provide better images.

AI integration

Another aspect that Dahua is focusing on is the deeper integration of Full-colour with AI

Another aspect that Dahua is focusing on is the deeper integration of Full-colour with AI. Full-colour technology is continuously being upgraded, and with that comes more intelligent solutions that can realise clear HD images at night, like it is during day time.

The TiOC, for example, combines Full-colour, AI, and Active Deterrence (warning lights and siren) into one comprehensive solution, realising a closed-loop system that involves early warning, active deterrence, and backtracking. It has been recognised by many authoritative organisations in the industry and even received distinctive awards.

Intelligent analysis and computing

What’s more, with the constant development of this technology can enable Full-colour imaging to be directly applied to intelligent analysis and computing.

It will become a mainstream technology that everyone can avail and use to optimise their scenarios, which is in line with Dahua’s mission of “Enabling a safer society, and smarter living.”
