The number of cases in which crime scene security
camera videos lead to the arrest of the perpetrator
is increasing. In our changing social
environment in which crime is increasing, the
demand for security cameras has been growing
Security cameras are used 24 hours a day, 365
days a year in a wide range of environments.
As a result, the performance and reliability of
these cameras has come to be seen as extremely
important, especially the light resistance characteristics,
which allow their use in environments
in which the cameras are subject to long
periods of intensely bright ambient light.
Furthermore, security cameras also need to
clearly image events that occur in places so
dark that it is hard to see with the naked eye.
Thus sensitivity in low ambient light conditions
is seen as the most important characteristic
for security cameras.
Sony CCDs have maintained an industry-leading
share in security camera applications, and
the Sony “Super HAD CCD”, which boasts
high sensitivity, is well-known in the industry
and widely used in security camera applications.
Sony has now improved the sensitivity of the
existing Sony security camera “Super HAD
CCD” and developed the new “Super HAD
CCD II”. This article introduces the features of
the “Super HAD CCD II” device.
