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.
Electronic 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.
Wide dynamic range
Frame noise reduction
Digital slow shutter
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.

Digital output is a REC656 data stream
(YUV422, synchronous embedded 8-bit signal,
interlaced output), compatible with a large
number of encoder ICs.
Micro coaxial cable can be
used for digital interface.
*Due to high-resolution CCD (NTSC 410K/PAL
470K), frequency and resolution differ from
REC656 specifications.
