OmniVision launches new sensor for edge facial biometrics with 4 MP resolution


OmniVision Technologies has announced the launch of a new 2.9 micron pixel image sensor with 4 megapixel (MP) resolution to its Nyxel near-infrared (NIR) and ultra-low light (ULL) product family to support accurate biometric facial recognition at long distances.

The new OS04A10 sensor provides security cameras with greater zoom and detection range, and improves the object identification and facial authentication accuracy of AI-enabled surveillance systems, according to the announcement. OmniVision says it also provides the industry’s best performance for incident detection, day or night, in both visible and NIR wavelengths.

“In addition to requiring top performance in all lighting conditions, security and surveillance camera designers are demanding higher resolution for greater facial recognition accuracy with longer zoom range,” comments OmniVision Business Development Director Brian Fang. “By combining our industry-leading NIR and ULL technologies with 4 MP resolution, the OS04A10 is designed to meet the evolving needs of security and surveillance systems.”

Nyxel NIR technology’s 940nm lighting cannot be detected by human eyes, and therefore will not disturb sleeping occupants or alert intruders they are being recorded. The company also says the sensor captures high quality images with a smaller amount of NIR light than other competitors, as measured by NIR SNR1, allowing high performance with low power consumption.

OmniVision’s PureCel-S die stacking technology separates the imaging array and processing functions and reduces power consumption, for smaller camera modules with greater design flexibility, the company says.

The company launched a 2 MP sensor combining its Nyxel NIR technology with ultra-low-light technology last year, and recently launched a sensor for Windows Hello facial recognition on 2-in-1 laptops.
