October 15, 2022 – Hikvision, an IoT solution provider with video as its core competency, released new ColorVu offerings for more vivid 24/7 colorful imaging, and has first included Hikvision ColorVu 4K and ColorVu varifocal cameras in the full-color range.
In video security, color-related information is crucial to identifying details of events especially at night. Conventional cameras with infrared lighting only provide black and white images for night monitoring. As a result, people, vehicles, or other important objects can easily be blurry and blend into the background, which makes it difficult to distinguish critical elements. Hikvision ColorVu technology resolves this common challenge faced by many security camera users, enabling cameras to produce colorful videos even in extremely dim environments.
“Since 2018 when we introduced the first generation of ColorVu cameras to the market, they have been one of our best selling products. The demand for low-light cameras continues to increase in the security industry, and we’re glad to see that our new ColorVu offerings can bring even more vivid imaging experience to our customers,” said Frank Zhang, President of International Product and Solution Center at Hikvision.
The newly released ColorVu cameras offer enriched options to the market with having covered both Turbo HD (DF8T series/DF3T series/DF0T series) and Network products. The enriched ColorVu series can satisfy a multitude of customer needs, from high-performance products to budget-friendly choices and smart solutions.
Hikvision has now included 4K ColorVu cameras in its product range, which brings color imaging to ultra-high-definition levels day and night. With better image quality and richer detail, 4K ColorVu cameras can be applied across an even wider range of scenarios including stadiums, airports, harbors, and parking lots, where clear and high-resolution images are necessary.
In addition, Hikvision has also added varifocal cameras (the DF8T-Z series) to the new ColorVu models to create 24/7 color imaging in all focal lengths. With 2.8 - 12 mm motorized lenses, ColorVu varifocal cameras will allow users to zoom in on colorful images at night.
The newly released ColorVu cameras lenses have kept the F1.0 super-aperture design, allowing four times more light to enter the lens than conventional cameras (that have F2.0). Focusing on high definition camera with an F1.0 large aperture is a big technical difficulty for the industry since the production requires very strict and accurate manufacturing processing. Hikvision has applied its advanced Active Alignment (AA) Technology in the production of ColorVu cameras to bring the adjustment accuracy to within 4 pixels, even smaller than 1/30 hair diameter.
Meanwhile, with optimized sensors, nighttime color imaging of ColorVu cameras renders much more brightly than conventional cameras. A new 3D dynamic noise reduction (DNR) algorithm helps the cameras record additional remote details clearly and deliver sharper images. In addition, ColorVu cameras are equipped with a soft and warm supplemental light that illuminates to guarantee color imaging even in zero-light environments.
Most security camera users only need to focus on alarms triggered by humans and vehicles, especially at night. These newly released ColorVu cameras can integrate Hikvision’s cutting-edge AcuSense technology to help users focus only on events that matter to security. Empowered by deep learning algorithms, ColorVu cameras can distinguish people and vehicles from other moving objects such as rain, leaves and animals. Alarms will only be triggered when the pre-set intrusion type takes place. With this solution, video clips are sorted by human and vehicle categories, and object classification vastly improves search efficiency.
