Hikvision presents its new ColorVu 4K cameras with AcuSense technology

The new ColorVu cameras from Hikvision provide video surveillance 24/7, with 4K color resolution and AcuSense advanced video analytics, based on artificial intelligence.

In the field of video security, Color-related information is crucial for identifying event details, especially during the night. Conventional cameras with infrared illumination only provide black and white images for night monitoring.

The result of this is that people, Vehicles or other relevant objects are often blurred and blend into the background, which makes it difficult to distinguish the true objectives. The technology Hikvision ColorVu solve this challenge with these new cameras, producing high-resolution color videos even in extremely dark environments.

How do you explain Carlos Hernandez, product manager de Hikvision Iberia, “from 2018, when we launched the first generation of ColorVu cameras, We have not stopped evolving, incorporating new devices and functionalities, adapting to the needs and requirements of the market. Our portfolio includes everything from high-performance intelligent solutions to more economical options for SMEs and small businesses.”.

The ColorVu series covers the range Turbo HD (series DF0T, DF3T, DF8T, DFT y HFT), in its bullet versions, minibullet y turret, with different lenses (fixed and motorized varifocals) and resolutions of 2 y 5 megapixels, with models with PIR and integrated siren.

in the versiones IP, ColorVu has cameras with resolutions of 2, 4 y 8 megapixels, in bullet versions, flush, minidome and PTZs. Some devices also integrate a microphone, siren and strobe, to which the new ones are now added sistemas 4K and technology AcuSense.

Innovation in technology

ColorVu cameras' strong ability to capture details in low light comes from two specific advancements in hardware technologies.: High-performance lenses and sensors.

The new ColorVu camera lenses have maintained the large aperture design F1.0, allowing four times more light to enter the lens than in conventional cameras (with F2.0).

Focusing a high-definition camera with a large F1.0 aperture is a great challenge and technical difficulty for the industry, since the production requires very strict and precise manufacturing processing. Hikvision has applied its advanced technology Active Alignment (AA) in the production of these devices to bring the precision of adjustment to 4 pixels.

With optimized sensors, Color images at night from ColorVu cameras are reproduced much brighter than conventional ones. A new dynamic noise reduction algorithm (DNR) 3D helps record additional details clearly and deliver much sharper images.

Besides, ColorVu cameras are equipped with a soft, warm supplemental light that illuminates to ensure color images are obtained, even in unlit environments.

With better image quality and a spectacular level of detail, 4K ColorVu cameras are especially suitable for open spaces and large environments, like big stadiums, airports, ports and parking lots.

Deep learning algorithms (deep learning) that they incorporate allow people and vehicles to be distinguished from other moving objects, like animals, leaves or rain, so that the alarms are only activated when the intrusion occurs.
