OmniVision Technologies, Inc., introduced the OS05A20, the first image sensor to implement OmniVision’s breakthrough Nyxel™ near-infrared (NIR) technology. This five-megapixel color image sensor leverages the PureCel® pixel architecture and Nyxel technology to capture bright, crisp videos and images, day and night. The OS05A20 achieves a significant improvement in quantum efficiency (QE) when compared with Omnivision’s earlier generation sensors. The OS05A20 can see better and farther under low- and no-light conditions, making it an ideal imaging solution for professional surveillance systems.
According to IHS Markit, the global shipment of network surveillance cameras will approach 100 million units in the near future. The research firm says this significant demand with increased investment in border protection and city surveillance as well as growth in the China market. Technology improvements are seen as vital for surveillance equipment providers to remain competitive. Video cameras with excellent night vision can greatly improve the quality of image data while reduced power consumption can enable longer battery life and provide more options for device makers.
With NIR sensitives that exceed 850 nm, the OS05A20 image sensor delivers unrivaled image quality, extends image-detection range for improved image data and reduces the light-source requirement, leading to lower power consumption and the ability to provide covert surveillance. But leveraging OmniVision’s new Nyxel technology, the OS05A20 achieves a significant QE improvement at 850 nm and 940 nm while maintaining high modulation transfer function. It captures high-resolution 2688X1944 video at 60 frames per second. It also comes in a larger 2 x 2-micron pixel format for improved sensitivity.
OmniVision will be showcasing the OS05A20 with Nyxel technology at the China Public Security Expo (CPSE) at the Shenzhen Convention & Exhibition Center from Oct. 29 to Nov. 1, 2017.
