Smart Control
(SSC-DC10P/14P/18P/50AP/54AP/58AP/CX34P)
Strong backlighting can often cause the subject of the
picture to be cast into shadow. To overcome this
problem, Smart Control achieves the optimum balance
between Iris and Gain settings in a unified digital signal
processing circuit. As a result, clear colour images can
be obtained even under severe or varying lighting
conditions. Smart control also works intelligently as it
employs average light metering to detect the position of
the major subject, and Fuzzy Logic to calculate the
proper exposure.
Monitor technology
Trinitron CRT
Sony incorporates Trinitron CRTs in all of its surveillance
colour monitors.With its completely original design, the
Trinitron technology allows for high resolution and the best
possible picture reproduction. The completely flat, straight
vertical surface of the Trinitron CRT provides the lowest
purity imperfection available with the CRT technologies of
today. Moreover, Sony manufactures its own CRTs to assure
quality performance in all of its monitors.

Camera technologies
Exwave HAD TM (SSC-DC50AP/54AP/58AP)
In monitoring and surveillance applications, camera
sensitivity is one of the most important factors in
obtaining an adequate picture in low light conditions.
The sensitivity of Sony cameras using the Exwave
HAD CCD is well over twice that of the cameras using
the Sony Hyper HAD CCD. The Hyper HAD sensor
structure has an OCL (on chip lens) located over each
pixel. The result is that light is concentrated on the
photosensor areas and the sensitivity of the camera is
improved. The Exwave HAD takes the Hyper HAD sensor
technology a giant step further. The OCL of the Exwave
HAD CCD is a nearly gap-less structure, eliminating the
ineffective areas between the microlenses. This enables
the hole accumulated layer to receive the maximum
amount of light.
Moreover, the smear level of the Exwave HAD CCD is
reduced to 1/50th that of the Hyper HAD CCD.
This leakage is dramatically reduced because the
improvement of the unit cell structure minimizes the
unnecessary reflection of the light onto the CCD surface.
