Urban surveillance is a major use case in the “smart city” concept that has been drawing increased attention recently.
There is a particular need for image sensors capable of high performance under low-light conditions to contribute to nighttime visibility.
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.
