Surveillance cameras are provided for people's safety and security.
However, they are of little use unless they provide a clear image in a variety of environments.
Continuing advances in Sony's CMOS image sensors provide clear images even in adverse conditions,
allowing us to provide the necessary quality for our customers' high-quality surveillance camera designs.
The most essential characteristic required for surveillance cameras is a high degree of sensitivity.
Now for the first time, a back-illuminated pixel developed specifically for surveillance camera
has resulted in an outstanding improvement in sensitivity over our previous product structures.
When surveillance cameras are used in low light conditions, high sensitivity is also required in
near-infrared illuminated environments. To meet this requirement, Sony has developed a CMOS image sensor
with higher sensitivity not only in the visible light range, but also in the near-infrared light range.
The focusing characteristics were optimized in order to bring out the maximum light
gathering effectiveness of the back-illuminated structure. As a result, we were able to achieve
good incident angle characteristics compared with our existing front-illuminated structures.
