The ability of a camera to deliver noise
and ghost free images under low light
conditions is fast becoming an essential
requirement for IP CCTV imaging
solutions.
The delivery of high quality images under
low light conditions presents numerous
technical challenges. Increased
image noise levels resulting from signal
amplification and image ghosting
caused by slow shutter speeds are
commonly encountered issues when
using existing CCTV technology within
a low light environment.
Recognising the importance of noise
and ghost free images in low light, SONY
has developed its unique eXcellent
Dynamic Noise Reduction (XDNR)
technology specifically for the IP CCTV
environment.
XDNR utilises advanced 2DNR and 3DNR
signal processing methods in order
to remove random and fixed noise
and image ghosting, eliminating the
motion blur normally associated with the
capture of moving images in low light.
Delivering superior image quality in low
light, SONY XDNR offers the optimum in
noise reduction performance for IP CCTV
solutions.
Sony HD SNC-RH PTZ cameras and
SNT-EX/EP encoder solutions offer XDNR
as a standard feature.
Using SNC–RH PTZ cameras combines
the quality of high definition video
with the superior noise and ghost free
images offered by Sony’s unique XDNR
technology. By migrating to the Sony
range of SNT-EX/EP encoders, XDNR
performance can be added to any
existing cameras and offers the perfect
hybrid solution.
XDNR technology from Sony offers
the optimum in low light imaging
performance. Available from a range of
products the technology is ideal for new
or existing installations for superior image
capture in low light conditions.
XDNR delivers superior noise and ghost free images under

From a surveillance solutions
perspective, the transition to HD CCTV
provides significant benefits. HD CCTV
technology delivers real time capture
and delivery of highly detailed images
over a wide field of view, highly
accurate object detection, recognition,
recording and display allow for forensic
levels of image analysis not found in
existing technology.
Sony HD CCTV solutions combine the
benefits of digital technology with the
ease of use of analogue to provide
the optimum in video security systems
performance.
HD CCTV is based upon technology
designed for use in high quality
broadcast television applications.
Video is captured using specialist High
Definition CMOS sensors, the sensors
contain a pixel array far greater than
that found in standard definition CCTV
sensors, this results in vastly superior
image quality and a greatly enhanced
field of view.
Additionally the CMOS sensors utilise a
progressive scan system which eliminates
the image flicker and blurring associated
with interlace scanning systems normally
found in standard definition CCTV
technology. The resulting images can
be transmitted via a suitable network in
a variety of data formats. For maximum
flexibility and optimum performance
Sony HD CCTV solutions provides H.264,
MPEG-4 and JPEG video compression
formats.
Sony HD CCTV solutions deliver
additional enhancements to image
quality by utilising Sony’s unique
eXcellent Dynamic Noise Reduction
(XDNR) and Visibility Enhancer (VE)
technology.
XDNR provides clear images by
drastically reducing the image noise
and motion blur encountered under low
light illumination. VE optimises scene
visibility by improving wide dynamic
ranges under conditions of high
contrast illumination.
The superior image quality provided
by Sony HD CCTV solutions delivers
significant advantages when coupled
with the powerful video analytics
capability of Sony’s Advanced
Distributed Enhanced Processing
Architecture (DEPA). DEPA technology
offers advanced, intelligent alarm
functionality whilst distributing and
sharing image processing across the
network. This powerful combination
results in a reduced operator workload
through vastly improved alarm
handling, superior use of network
resources and a security solution
that’s more flexible, scalable and
economical.
