Uniview LightHunter IP Cameras see Color in the Dark

Lighthunter IP Cameras see color in Ultra Low Light

See Color in the Dark

The main goal of video surveillance is to see clearly anytime and anywhere. Security Cameras need to be well prepared to provide high-resolution, and color images, in a multitude of different lighting conditions. The LightHunter Technology is an innovative technology that delivers vivid color, appropriate brightness, and extremely clear images in ultra-low light. LightHunter Technology significantly improves the image brightness with an F1.2 Large Iris design and a BSI sensor. With the specially designed, large size sensors, the IP Cameras have higher photosensitivity, and feature high SNR.

UNV’s uniquely patented technology called U-ISP,  improves the definition and brightness of images. U-ISP technology features a new generation of noise reduction to improve Signal-Noise Ratio and reduce blur. It effectively reduces blur with moving objects, which ensures that the image is captured more like the true scene. With the combined hardware and software advantages, LightHunter Technology guarantees extraordinary images, full of color, even under ultra-low light.

Low Light Challenges for Security Cameras

Indoor Scenes and Challenges

Installing Security Cameras in certain venues with complex lighting creates unique challenges. If you have ever installed a Security Camera System in a business that operates in Low Light, you may have noticed that the Cameras are always in Black and White (IR Mode). Since color images are more detailed and accurate, this is an issue. LightHunter Technology solves this problem. Therefore, your clients are much more satisfied with the finished product. Color images provide much more forensic detail, which provides end users with a more usable surveillance image. A typical example of this would be a Bar or Restaurant that operates in lower light levels.

Outdoor Scenes and Challenges

Many outdoor scenes create unique challenges as well. If you are covering an area with limited ambient lighting, then you need a camera with the capabilities of a LightHunter Camera. This is especially true for high security areas. Have you ever tried to identify a person or object from an image of a camera in IR Mode? If so, then you are familiar with the challenge. Is your subject moving? What is that item they are carrying? Obviously, it is much easier to extract these details from a color image. In addition, IR Mode images can produce other issues such as blur or noise. LightHunter employs U-ISP technology to reduce the issues associated with other Low Light Imaging Technology.

In low-light environments, standard IR technology can achieve high-resolution, while it may lose color information and the images are black and white. The Lighthunter technology provides superior color-related information unable to be achieved with conventional cameras. More effective information about vehicles and suspects, such as the plate number, color, and brand of a vehicle; facial features, hair color, height and clothing color of a suspect may be usefully offered to law enforcement or other people in need.

Committed to solving this problem, UNV has devoted significant resources to the research and development of this new ultra-low light technology. Now, LightHunter technology is available and provides unmatched detail, brightness, and realistic color, along with clear images in the ultra-low light.

BSI Sensor and High Transmittance Lens

The BSI Sony Sensor improves light utilization many times that of ordinary sensors. In addition, Lighthunter employs a High Transmittance Lens for LUX Levels of 0.0005.

LightHunter U-ISP Technology

In addition, the UNV new-generation algorithm (U-ISP) has many advantages, such as reducing blur and noise, and increasing sharpness. All of these advantages improve the definition and brightness of images. As shown in the following figure, a criminal is stealing a wallet from the car. The normal IPC’s image is full of snowflakes. The most obvious difference compared to the normal IPC’s image, is that we see clearer and more colorful images and obtain more detailed information by the LightHunter IPC. The detailed information, such as facial features, clothing color, and plate number is easily identifiable by law enforcement.

850nm vs. 940nm, IR Wavelength Comparison for CCTV Applications

There are two common IR wavelengths used in CCTV applications today. IR or Infrared wavelengths are measured in ‘nm’ or nanometers, which are used to specify the wavelength of electromagnetic radiation near the visible part of the light spectrum. Visible light ranges from about 390 to 700nm. The IR in CCTV applications take over from there, commonly 850nm and 940nm, which allow us to see images that would normally fall outside of our visible range, thus IR Illuminator. These IR LED’s are used to produce, or improve ‘Night Vision’ capabilities for security cameras.

Although the IR wavelengths 850nm and 940nm, respectively, are fairly similar in performance, there are a few important differences worth noting. The use of IR LED’s in security cameras has become commonplace as technology has improved dramatically and cost has come down. Generally, the great majority of security cameras or CCTV Cameras are sensitive to the 850nm wavelength. Although the IR light is invisible to the human eye, the IR LED’s will produce a faint red glow when looking directly at the camera or source.

The main advantage of the 940nm wavelength is that the IR LED’s do not produce any visible glow. In other words, they are completely invisible and can be used in applications that are required to be more covert. In fact, many people refer to them as ‘Covert IR’. This type of IR is also useful in places where a red glow may be mistaken as a signal and can not be used. The disadvantage of 940nm is that they are about 30-40% less effective and will illuminate less distance.LUMI-390

When using a separate, or stand-alone IR Illuminator such as the LUMI-240 IR Illuminator , it is important to make sure your CCTV camera is sensitive to the same wavelength as emitted by the illuminator. In other words, if the illuminator is 850nm, your security camera must be sensitive to that wavelength. Most cameras are sensitive to 850nm. Security Cameras that are 940nm are available as well, but much less common.

Most Security Cameras with built in IR LED’s, use an IR Cut Filter in order to maximize different lighting conditions during the day or night. During the daytime, the filter is on in order filter out Infrared Light, that way, color images are not distorted by IR Light. During the nighttime, the IR cut filter is automatically switched off to allow infrared light to enter the camera. The camera switches to IR Mode (Black and White) which is more sensitive to Infrared light.

IR technology has made great strides in recent years which is a great benefit to consumers and commercial CCTV users. SMART IR, Black Film Technology and STARVIS Sensors are among the exciting new Night Vision improvements in the surveillance industry. It is now possible to see extreme distances during day and night with high powered IR LED’s and IR Illuminators. If you are planning a CCTV Installation that requires night vision, it is certainly beneficial to understand the options that are available to you. At Ellipse Security, we are always ready to assist with your planning and design needs.
