Advanced digital signal processing (DSP) technology ensures outstanding color reproduction and low light performance, capable of capturing details such as facial features, clothing, and automobile colors that can serve as vital evidence. Setting a new standard for imaging quality, night or day, the Hitachi VKS655EN marks another phase in the evolution of high-quality digital surveillance systems.
A newly designed 36x auto-focus optical zoom lens delivers enhanced resolution, clearly capturing subject details at a distance. Proprietary Hitachi auto-focus control makes it possible to track rapidly moving subjects, while the addition of Digital processing boosts sensitivity to a maximum of 1/1-second (VK-S655N) or 1/0.75-second (VK S655EN) exposure time, making it possible to capture bright, clear images in a variety of lighting situations.
In daylight conditions, the IR cut filter ensures clear, high-quality color images. At night or in other very low light situations, the IR cut filter is automatically removed to allow capture of bright, high-contrast black and white images. a 12x digital zoom delivers a maximum zoom factor of 432x. The improved lens design produces crisp clear details, even in peripheral areas of the image.
One extremely important requirement in the surveillance and crime prevention fields is the reproducibility of actual colors. The Hitachi VK-S655EN recreates the actual color to the fullest extent possible not just in well-lit areas, but in darker ones, allowing more accurate depiction of the surveillance area. High-performance CCD teams with digital signal processing to achieve outstanding low-light performance, capable of capturing images in standard mode at a minimum subject illumination of 1.0 lx.
Hitachi's frame noise reduction minimizes random noise and after-images often associated with moving subjects, making this high-performance unit suited to a variety of surveillance scenarios. Producing clear, sharp images even in challenging low-light conditions, this technology also facilitates image compression in network camera systems.

At night or in other very low light situations, the IR cut filter is automatically removed to allow capture of bright, high-contrast black and white images.
The VK S655EN can also provide the same 35x zoom mode as in the VK-S654N/EN. A 35x compatibility mode is available to ensure that no picture display problems occur even due to changes in the angle of view. Switching from the VK-S654N/EN will pose no problems caused by the difference in magnification.
