The ability of a camera to deliver
optimised images under extreme lighting
conditions is known as its wide dynamic
range capability. Wide dynamic range
is an essential feature when considering
image capture under demanding
lighting conditions.
Video surveillance technology has
traditionally failed to deliver high
quality images under the demanding
conditions of high contrast scene
illumination. Delivering wide dynamic
range by resolving bright and dark areas
of the image challenges traditional
image processing technology.
Existing technology may be optimised for
either bright or dark areas of the scene,
but not simultaneously. The resulting effect
is the reduced visibility of target objects.
In response to this problem Sony
has developed its unique Visibility
Enhancer (VE) technology. During image
processing VE captures and dynamically
monitors signal levels, reducing the
extreme levels of brightness within
the scene and increases levels within
the darker areas. This simultaneous
processing and adjustment of both
light and dark areas of the scene
delivers improved wide dynamic range
performance with enhanced scene
visibility and superior image quality.
Sony HD SNC-RH PTZ cameras and
SNT-EX/EP encoder solutions offer VE as
a standard feature. Using SNC–RH PTZ
cameras combines the quality
of high definition video with the wide
dynamic range capability offered
by Sony’s unique VE technology.
By migrating to the Sony range of
SNT-EX/EP encoders, VE performance
can be added to any existing cameras
and offers the perfect hybrid solution.
VE technology from Sony offers the
optimum in wide dynamic range
performance. Available from a range of
products the technology is ideal for new
or existing installations for superior image
capture in all lighting conditions.

Video surveillance has historically been
dependent upon human intervention
and control, the system operator often
providing the interface between alarm
activations and required actions. The
inability of the operator to monitor and
process multiple alarm events is often
cited as the weak point in traditional
surveillance systems.
The more recent introduction of intelligent
video and alarm analysis has provided
a reduction in operator workflow by the
addition of pre-configured alarms,
linked to pre-programmed actions.
As a result of its processor intensive
requirements video analysis can however
be cost prohibitive for many systems,
especially in the analogue environment.
Introduced in 2006 Sony’s unique
Distributed Enhanced Processing
Architecture (DEPA) addresses this issue
with an innovative design approach.
SONY DEPA is an embedded technology
providing pre-processing of image data
within its camera technology and post
of processing of image data within its
recording and monitoring solutions. Alarm
and image meta data generated by
the camera is transmitted on demand to
the recording solution where appropriate
alarm actions may be initiated.
This distributed architecture allows for
intelligent use of network bandwidth and
reduces the bottlenecks associated with
existing video analysis systems.
Operating a continuous product
development policy SONY introduces
DEPA Advanced technology. Building
upon existing success, DEPA Advanced is
an enhanced DEPA technology and now
offers the highest quality image analysis
and detection. SONY’s embedded DEPA
Advanced technology delivers unrivalled
analytical performance within a range
of imaging, recording and monitoring
products.
Utilising SONY’s unique Intelligent Motion
Detection (IMD) to determine real or
environmental movement and Intelligent
Object Detection (IOD) to monitor the
image for violation of a predetermined
rule, DEPA Advanced provides highly
accurate image meta data to the
recording and monitoring solution for
alarm activation and processing. A
comprehensive range of enhanced
predetermined alarm filters include,
tamper alarm, virtual fence, trip wire,
missing object, people counting and anti
loiter options, audio analysis completes
the range of advanced features on offer
with DEPA advanced technology.
SONY offers a comprehensive range
of embedded DEPA Advanced
products from the Sony HD SNC-RH PTZ
cameras and SNT-EX/EP encoders to
NSR1000 recorders and RSM Advanced
monitoring software solutions. A
comprehensive range of accessories
combine to provide the complete DEPA
Advanced end to end solution.
Minimising false alarms whilst maximising
operator workflow and bandwidth
usage, SONY DEPA Advanced offers the
optimum in cost effective, flexible and
scalable video analysis solutions.
Building upon the success of DEPA, DEPA Advanced is an
enhanced technology that offers high quality image analysis
and detection.
