High-Sensitivity Camera
High-Sensitivity Color Camera (NC-R550)
Unlike an infrared camera, the NC-R550 has an image processing mechanism that puts it on par with the most technologically advanced visible-light cameras on the market. Its digital processing and digital noise reduction circuits produce advanced image quality, comparable to that of state-of-the-art broadcasting cameras. Even low light conditions such as starlight present no challenge.
The NC-R550 is the first High Sensitivity Color Camera to use 3 EM-CCDs (electron-multiplying CCDs). This enables it to produce high-quality, full-color images even in starlight, new moon conditions, and full darkness. How?
- Weak signals are multiplied before the output amplifier can add readout noise. This renders read noise virtually negligible.
- The actual colors (clothing, hair, etc.) are reproduced due to its "fully automatic white balance."
- The images are automatically optimized by the electric gain, pixel addition, digital gain, accumulation time, and shutter speed functions and are suitably adjusted for the environment.

Your security camera picks up unusual footage: a mysterious ship, barely visible in the distance. If you're using an ordinary infrared camera, there's no hope of picking up the letters on the ship, not to mention details of the suspicious persons on board, such as clothing colors or facial features. The new High Sensitivity Color Camera from NEC offers an elegant solution. Its extended luminance range for capturing images under low light conditions is a unique feature in today's marketplace.
NEC offers CCTV solutions for essential facilities ranging from airports and seaports to nuclear plants, jails, and customs agencies. NEC has a strong commitment to customer satisfaction and takes pride in customizing products to the circumstances, national standards, and projected monitoring targets of individual clients. Clients can choose the specific lens, housing and pan-tilt head, stabilizer, type of camera, number of cameras, and set-up locations most suitable to their individual needs.
NEC also offers additional options.
- Lenses with magnification ranging from 20 to 35x. The maximum distance at which a person can be recognized is 1 kilometer with the 20x lens and 5 kilometers with the 35x lens.
- A built-in focal length extender and special zoom ratio.
- Innovative networks between cameras, enabling customers to effortlessly integrate management platforms and remote offices, resulting in a powerful surveillance arrangement that can cover an impressive expanse.
Portable High Sensitivity Color Camera
The High Sensitivity Color Camera also comes in a portable version, called the Portable HSC.
This portable HSC is attached to a monitor and comes complete with a recorder and a battery. It's a handy product for surveillance on the move: clients include police officers who use this camera during stakeouts.
It has plenty of state-of-the-art features, making it an attractive candidate for today's video surveillance needs. One of the most appealing selling points is that it uses CCDs. These devices electronically multiply charges generated through photoelectric conversion, so users can shoot video in low light conditions such as starlight without a charge storage function. High quality nighttime photography is both possible and simple because the camera uses an IR pass filter and a near-infrared floodlight at the same time. This, along with an ND filter, releases the lens from extreme aperture squeezing in outdoor situations in the daytime. NEC uses ground-breaking LSI circuits developed in-house that take advantage of the latest digital signal processing technology. All this adds up to a camera that is both multi-functional and far more stable than previous models.
The camera can take impressively clear images even at low luminance because of its advanced functions and digital noise reduction that users control optimally with microcomputers. All this is individually tailored to clients' specific needs. For example, NEC pays special attention to different monitoring and lighting conditions. The 10 maximum digital zoom means users can instantly enlarge images on the display screen. What's more, the extensive scene files make it possible to register individual camera settings for space monitoring under different conditions.
Un-cooled Infrared Camera
The infrared camera is superior at creating images not only in total darkness but also in low-visibility situations such as night and backlight. The images are not affected by sunlight or shadows because they are created by the heat differences. NEC group can provide various types of infrared sensors and cameras.
