Hitachi VK-S654N/EN 35X Optical Zoom Block Camera

Aug. 10, 2012 - PRLog -- Advanced digital signal processing (DSP) technology ensures outstanding colour reproduction and low light performance, capable of capturing details such as facial features, clothing, and automobile colours that can serve as vital evidence. Setting a new standard for imaging quality, night or day, the Hitachi VK-S654N/EN marks another phase in the evolution of high-quality digital surveillance systems.

The high-performance CCD combined with advanced 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.



Digital processing boosts sensitivity to a maximum of 1/1 second exposure time, making it possible to capture bright, clear images in a variety of lighting situations.   When a surveillance scene includes bright and dark areas, alternate images are captured at optimum exposure for both levels of illumination, and the resulting two fields are combined into a single frame. This produces clear, glare-free images in a variety of lighting conditions, such as entrances with varying levels of indoor/outdoor illumination and situations where backlighting can make it difficult to identify facial features.


Conventional surveillance camera systems using interlaced scanning are not capable of producing clearly identifiable images of moving cars or people. The interlace method uses two scans to create a single image frame, producing jumpy, poorly defined images when still images are pulled from the video feed. Progressive scanning incorporated in the Hitachi VK-S654N/EN records the frame in a single sequential scan, creating sharp, high resolution still images, with clearly defined lines and contours.

Based on Hitachi’s track record of pioneering image stabilization technology, electronic image stabilization compensates for vibration or movement of the camera, automatically minimizing image blur.
