        Advanced digital signal processing ensures outstanding color reproduction. Characterized by 
superior ability to accumulate available light, the high-performance CCD produces sharp, clear 
images even in challenging lighting conditions. And accurate color reproduction enhances security 
performance in a variety of surveillance scenarios. This digital surveillance camera can capture 
details such as facial features, clothing, and automobile colors clearly and accurately, producing 
true-to-life surveillance images that can serve as vital evidence.
    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.
Optical zoom permits confirmation of facial features.

    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. 
E
lectronic image stabilization
      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.

        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.
     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.
    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.
      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. 
Privacy zone masking function
  This function makes it possible to mask the camera’s view 
of areas subject to privacy concerns, such as windows and 
entrances. The position and size of the mask is maintained, 
even when the camera pans, tilts or zooms, making this unit 
particularly suitable for surveillance of public areas.
Motion detection
  This function triggers an alarm when motion is detected in 
designated areas of the surveillance frame. Motion detection can 
be activated in as many as eight frame blocks out of a total of 64.
Compatibility 
facilitates system 
upgrades
 The VK-S654N/EN offers 
effortless upward compati-
bility with the VK-S654R/ER, 
making it easy to upgrade 
and incorporate the latest 
technical advances in your 
surveillance systems.
Built with the 
environment in mind
 The RoHS-compliant VK-
S654N/EN meets guidelines 
for permissible levels of lead, 
mercury, cadmium, hexa-
valent chrome, PPBs and 
PBDE, making it an eco-
friendly way to implement 
high-tech surveil-lance.
Digital image flip
 Images can be flipped verti-
cally or horizontally, enabling 
tracking of subjects moving 
underneath the camera in a 
single continuous shot.
