Sony introduces new SSC-E470 series camera in order to further strengthen Sony's analog
security camera line-up. This new SSC-E470 series is included in the category called
CS-Mount Color High Resolution type with Day/Night function which is expected to show CAGR
of sixteen percent between year 2002 and 2006 in terms of world wide quantity base. The
market share of CS-Mount Color High Resolution type with Day/Night function category
against total CS-Mount Color High Resolution type analogue security cameras is expected to
occupy ten percent in terms of quantity base in year 2002. Sony currently has one SSC
series (SSC-DC590 Series) within the CS-Mount Color High Resolution type with Day/Night
function category. Since SSC-DC590 series is equipped with Wide-Dynamic Range function, it
is targeted for customer segments such as financial industries which are different from
targeted segments of SSC-E470 series.
A Wide Auto Tracing White Range - ATW Pro & ATW
ATW is a feature that automatically adjusts the camera white balance to adapt to changes
in lighting conditions. SSC-E470 Series provides an extremely wide ATW range of 2,000 K to
10,000 K, allowing adjustment-free operation under a variety of light conditions. Users
can choose from two modes: ATW Pro and ATW. ATW Pro mode is ideal when the lighting
condition changes frequently and is particularly suited to applications where the operator
needs to see objects as they appear to the eye. This ensures that the precise color image
is always obtained.
Back Light Compensation
Unwanted backlighting can often cause the subject matter of the image to be cast into
shadows. The BLC function incorporated in these cameras automatically compensates for such
conditions and allows the subject to be more visible. The BLC mode is selectable between
OFF and ON.
CCD IRIS
SSC-E470 Series have CCD-IRIS function to automatically adjust the shutter speed depending
on the amount of incident light. As the image brightness increases, the camera adjusts the
exposure by automatically reducing the CCD photo sensor's exposure time (charge
accumulation time). The CCD-IRIS enables to continuously control the exposure by
electronically adjusting the shutter speed in the range from 1/60(NTSC) / 1/50(PAL) second
to 1/100,000 second. Manual iris lens with CCD-IRIS function can be used instead of more
costly automatic iris lens.
Turbo AGC
The SSC-E470 Series cameras are equipped with an advanced Turbo AGC function. This allows
the user to boost camera gain up to 24 dB, enabling viewers of the image to distinguish
the subject more easily - even if it is shot in low light. The AGC mode is selectable
between OFF and TURBO.
Day/Night function
SSC-E470 Series features a "Day/Night" capability, which provides optimized
sensitivity in both day and night shooting applications. Under low light condition,
SSC-E470 series automatically switches the infrared cut filter to a clear dummy filter and
changes to B/W mode. This results in minimum illumination of 0.05 lx which is a drastic
improvement from 0.55 lx in color mode. The refractive index of the dummy filter is
adjusted to visible spectrum, considering that there is some visible light even under dark
circumstances in the majority of cases. Therefore, if only infrared illuminator is
available as light source, the object will become out of focus with standard lens. There
are some near-infrared compatible lenses available from several manufacturers including
Cosmicar to avoid it.
State-of-the-Art SuperExwaveTM Technology
SSC-E470 Series incorporates a newly developed 1/3-type CCD with SuperExwaveTM technology
that achieves extremely high sensitivity levels and produces high quality images. This CCD
imager provides a minimum illumination of 0.55 lx at F1.2, enabling cameras to capture
clear and detailed images even under low light conditions. What's more, these cameras
reproduce images with a high picture quality of 380,000 pixels (SSC-E473) / 440,000 pixels
(SSC-E473P/E478P) and have an excellent S/N ratio of more than 50 dB.
Newly developed innovative DSP Technology
Unlike conventional DSP's, the newly developed DSP technology employed in these cameras
increases the horizontal resolution attainable by the CCD. Thanks to a combination of this
DSP technology and the SuperExwave CCD technology, these cameras offer a high-horizontal
resolution of 540 TV lines, providing amazingly clear and detailed images.
Slim and Stylish Design
These slim and lightweight color cameras can easily be installed in places where space is
limited and where installation was previously difficult for larger cameras. A stylish rear
panel cover and transparent lens cap come as standard on these cameras so that they will
not detract from the natural décor of the room in which they are installed.
