FEATURES
Progressive Scan CCD With ExwavePRO Technology
The SNC-DM Series and SNC-DS Series of cameras incorporate
advanced progressive scan CCDs with ExwavePRO technology.
They inherit the technical advantages of Sony ExwaveHAD
TM
technology, while incorporating progressive scanning and
complementary color filters to provide extremely high sensitivity
levels and clear, crisp images in both daytime and nighttime
environments. Complementary color filters are well suited in
cameras used for security applications because the luminance
signal-to-noise ratio is higher than when using primary color filters.
These cameras, with ExwavePRO technology, provide bright
images in low light conditions even when the camera has a
resolution greater than 1,000,000 pixels. The minimum illumination
of the SNC-DM Series is 0.8 lx in color at F1.3, and the SNC-DS
Series is 0.3 lx in color at F1.3.

Megapixel — High Resolution
The SNC-DM Series of cameras have a resolution of 1.3 megapixels,
which can reproduce clear and detailed images even at wide
viewing angles. These cameras are ideal for use at building
entrances and parking lots, where detailed images, such as those
of people’s faces and car license plates, are required.

Light Funnel Function for High Sensitivity
*1
Unlike systems that use slow shutter speeds to provide bright
images, the 'Light Funnel' mechanism is such that image data for
every two pixels are combined vertically and horizontally
providing extremely bright images even when monitoring moving
objects at dusk. This function can be activated automatically in
response to surrounding light conditions or on a pre-specified time
schedule.
(Fig. 3)
*1 When the light funnel function is activated, the image resolution is 640 x 480 (VGA).
JPEG Picture Quality Settings With Constant Bitrate
Algorithm
Users can preset the JPEG picture quality for these cameras from
a choice of ten levels. In addition, because the cameras
incorporate a constant bitrate algorithm, they can limit the data
bitrate while still maintaining high-quality images. This is useful for
calculating the required storage capacity and bandwidth during
installation.
Variable Gamma Settings
Users can choose from six preset gamma curves. By selecting a
gamma curve that is appropriate for a given scene, captured
images can be reproduced clearly and sharply.
