At nighttime, most traditional video surveillance systems lose their effectiveness. Black and white images, low visibility, and false alarms make it difficult to identify people and vehicles, leaving businesses, communities, and homes vulnerable to theft, vandalism, and intrusion.

Criminals take advantage of the darkness to act with impunity, knowing that conventional cameras will not capture key details such as the colour of clothing, the model of a car, or the face of an intruder. This limitation not only complicates immediate intervention, but also reduces the evidential value of the recordings.

Visiotech, as an official Hikvision distributor, offers a solution to this problem thanks to ColorVu 3.0 technology, which allows people, vehicles and critical situations to be identified even in complete darkness.

What is Hikvision's ColorVu 3.0 technology?

ColorVu is a technology that, regardless of the brightness of the environment, provides clear and detailed images that improve both security and the ability to react to any incident.

Hikvision’s ColorVu 3.0 cameras are ONVIF-compatible, ensuring integration with any NVR on the market. This technology revolutionises night-time video surveillance by delivering crisp colour images 24/7, even in total darkness. Thanks to ultra-sensitive sensors, F1.0 aperture, intelligent lighting and AI image processing, Hikvision offers an effective solution to the challenges posed by low light, helping to prevent theft and night-time incidents through accurate, detailed and continuous surveillance:

  • Accurately identifies people and vehicles in real time.
  • Provides clear and detailed visual evidence.
  • Deter criminal behaviour through visible and effective surveillance.
  • Reduces false alarms thanks to intelligent detection of real threats.

ColorVu 3.0 improvements in cameras

This technology is the third generation of ColorVu, featuring the incorporation of advanced artificial intelligence such as HikAI-ISP for image processing, AcuSense 3.0+AcuSearch for easier searches and fewer false alarms, and AI WDR that automatically adjusts according to the scene.

Colour vision

Thanks to the evolution of this version of ColorVu, Hikvision cameras offer even clearer, sharper and more detailed images, even in the same lighting conditions. Colours are reproduced more realistically and the level of detail is so accurate that no element goes unnoticed, even in scenes with movement or complex contrasts.

Among the improvements are:

  • Smart Hybrid Light: Colour images even in complete darkness thanks to intelligent lighting that alternates between warm white light and infrared.
  • Elimination of ghosting from moving objects and real-time noise reduction using artificial intelligence.
  • Audio 2.0 with a more powerful speaker system integrated with Smart PA (smart power amplifier).
  • Super confocal lens: sharper focus, as the lens aligns IR and visible light, improving brightness.
  • Smart features: intelligent image processing with HikAI-ISP, human and vehicle classification with AcuSense 3.0, quick search for relevant events with AcuSearch.
  • Automatic correction of shadows and contrast with AI WDR.
  • Automatic shadow correction
  • True-to-life, accurate colours thanks to 3D LUT technology
  • Comparison between ColorVu 2.0 and ColorVu 3.0

How does ColorVu help solve night-time video surveillance problems?

One of the main problems when detecting a night-time incident or obtaining evidence to identify the perpetrator or a vehicle involved is poor image sharpness, the appearance of shadows or blurred images that make it difficult to see or recognise the perpetrators. This is the well-known ghosting effect, which is present in many large aperture (F1.0) cameras and which, in addition to blurred images or shadows, can cause overlapping or duplicate images in the video.

To prevent the effectiveness of video surveillance from being reduced in these critical situations, where details are crucial for timely action and reaction, it is necessary to have clear and sharp images where details and characteristics can be easily identified.

Hikvision solves this problem by combining various technologies such as HikAI-ISP, which enables the image of the targets to be identified with complete clarity, clearly distinguishing their most relevant characteristics.

This improvement allows for accurate recognition of faces, number plates or movements, facilitating immediate detection and a more effective response to attempted theft or intrusion.

Ghosting effect

Another major challenge in CCTV is correctly managing the large amount of data and hours of recording generated by security systems. Although cameras record every movement, identifying and filtering which events pose a real threat is not always easy. Factors such as moving leaves, rain, reflections or shadows can constantly trigger false alarms, overwhelming operators and reducing system effectiveness.

To prevent this accumulation of alerts from reducing surveillance efficiency, it is necessary to have a tool capable of automatically identifying and filtering real threats, allowing operators to focus only on what really matters.

To this end, Hikvision has integrated AcuSense 3.0 into ColorVu cameras. This artificial intelligence-based technology analyses each event in real time, accurately classifying and filtering both people and vehicles, drastically reducing false alarms.

In addition, the AcuSearch function allows security teams to locate relevant events in seconds and review only recordings that provide value.

This combination of intelligent detection and 24/7 true colour vision makes ColorVu 3.0 cameras a solution that maximises operational efficiency, increases the evidential value of recordings and enables a faster and more effective response to any real threat.

What if the installation already has existing infrastructure?

In installations that already have cameras, recorders or software from different manufacturers, or that use older or basic technologies, it is not always possible to add advanced detection functions or improve image quality without making significant changes.

To avoid these limitations, ColorVu 3.0 cameras offer full compatibility with third-party systems thanks to the ONVIF standard, allowing a quick, cost-effective and scalable upgrade without replacing the existing system.

Recommended use cases for ColorVu 3.0 technology

Hikvision's ColorVu 3.0 technology can be applied in a wide variety of environments where night-time visibility and accurate detection are essential to ensure security.

  • Detached houses, terraced houses, semi-detached houses, blocks of flats or apartments.
  • Warehouses and factories.
  • Parks and gardens.
  • Squares and public spaces.
  • Industrial estates, logistics areas, technology or industrial parks, loading and unloading areas, production plant perimeters.
