KEY FEATURES
Exwave PRO
™
–
enhanced image performance.
Image performance is now significantly enhanced with Sony
Professional’s innovative ExwavePRO
™
technology, unique to
our fourth generation IP cameras.
Minimising motion blur,
enhancing clarity
Sony is a world-leader in the design
and manufacture of CCD (charge-
coupled device) and CMOS
(complimentary metal-oxide
semiconductor) imaging devices.
At the heart of our new ExwavePRO
™
technology is an all-new CCD design
– specifically developed to meet the
requirements of security applications.
Until now, CCD technology had only
been used with interlaced scanning
CCDs (typically designed for use in
camcorders), to capture fast movement
at a relatively high resolution.
For security applications, however,
motion blur can be a problem, with
the details of people or objects
becoming difficult to make out on
an interlaced image.
ExwavePRO
™
CCDs use progressive
scan technology – every frame of
video is captured at full resolution with
no interlacing. When trying to read the
details of a number plate on a fast-
moving car, progressive scan technology
effectively doubles the vertical resolution
of the image being analysed, giving
clear, precise results.

In addition, our ExwavePRO
™
also uses
a new Complementary Colour Filter
technology that results in approximately
twice as much light reaching the CCD.
This produces a normal looking video
output, but the higher luminance signal-
to-noise ratio results in an image that
can be twice as bright as one produced
using a Primary Colour Filter – ideal for
clear results in low light conditions.
ExwavePRO
™
technology is a key
feature of all of Sony Professional’s fourth
generation IP cameras. The introduction
of this technology, alongside our equally
innovative Light Funnel system, means
our security cameras deliver a higher
resolution imaging performance
than ever before.
