in a unified digital signal processing circuit. As a
result, clear color images can be obtained even
under severe or varying lighting conditions.
The Smart Control function also works intelligently.
Wherever the subject appears in a picture,
SSC-DC50A/ SSC-DC54A cameras sense the
entire area of the frame and measure the average
light level (No. 0). Where the position of the
subject can be defined in advance, the picture
optimization area can be preset to one of the
seven areas shown below (No. 1 to 7). By presetting
the detection area, faster backlight compensation
is achieved.

ALTERNATIVE WHITE BALANCE
CONTROL MODES
The SSC-DC50A/SSC-DC54A have four types of
white balance control modes - ATWpro, ATW, AWB
(one-push) and 5600° K - to meet a wide range
of operational conditions.
Advanced ATWpro mode
Ideal for frequently changing lighting conditions
and applications where the operator needs to see
objects as they appear to the eye. The effective
operational color range is 2500° K to 6000° K.
This mode makes optimum use of the capabilities
of the Smart Control function.
ATW mode
Allows the operator to see objects as they
appear during daylight. The color temperature
compensation range extends down to 2000° K
and up to 10,000° K.
AWB mode
Automatically memorizes the adjusted white
balance values every time the AWB button on the
side panel is pushed.
5600° K mode
Recommended when the cameras are used
outdoors during daytime operations.
CCD IRIS FUNCTION
As the illumination level of the scene changes,
the camera responds by automatically reducing
or increasing the exposure time of the photo
sensors. This is achieved by changing the
electronic shutter speed of the CCD, in the range
of 1/60 of a second to 1/100,000 of a second. The
CCD IRIS function is digitally controlled by the
advanced Sony Smart Control feature. The control
of incoming light by the CCD Iris function is
completely electronic and does not require a
conventional mechanical iris control facility inside
the camera. This means that reliability is greatly
enhanced. An added benefit of the CCD Iris
function is when the information is recorded
onto video tapes. For example, thanks to high
shutter speeds during the day, clear still images
can be obtained when the tape is reviewed.
This facilitates the identification of fast moving
objects such as license plate numbers.

VARIABLE SPEED ELECTRONIC SHUTTER
With the electronic shutter, you can capture clear,
blur-free pictures even if the subject is moving.
During playback of the recorded image, you can
obtain clear still or slow-motion pictures.
The shutter speeds are easily selected by
a rotary switch on the side panel.
Shutter Speeds
- 1/60, 1/100 (Flickerless mode),
1/250, 1/500, 1/1000, 1/2000, 1/4000,
1/10000 second
SIMPLE SINGLE CABLE WIRING
(SSC-DC50A ONLY)
The SSC-DC50A features optional Triple
Multiplexing operation. Using a single coaxial
cable, the video and sync signals can be
transmitted together with DC power from an
optional YS-W150/W250 Camera Adaptor. The
camera can be operated from these adaptors
by using a coaxial cable such as the 300 m
RG-59B/U (3C-2V) or 600 m RG-11A/U (7C-2V).
Since the SSC-DC50A has a MONITOR OUT
connector, the picture can be easily checked at
the installation point with a portable monitor.
The SSC-DC50A can also be operated from a
local DC 12V power source using a commercially
available power supply adaptor.
