SONY’s New Large-Sized 1/1.2 4K CMOS Sensor 2021-08-16

The need for security cameras to provide high-resolution imagery in the dark means more demanding requirements for image sensors as well. The IMX585 CMOS sensor is a new 1/1.2-type 4K-resolution CMOS image sensor based on back-illuminated pixel technology developed by SONY for use in security cameras. The latest image technology delivers low-noise and outstanding low-light performance, while the back-illuminated pixel technology provides high sensitivity and high dynamic range. Sensitivity in the near-infrared range is boosted by approximately 1.7 times (compared to IMX485). The outstanding image recognition and detection performance in dark environments make the new sensor the perfect choice for high-end 4K security cameras.

Key Features:

1. Increased dynamic range
