OV2281 1080p product brief lead free available in a lead-free package When recording full-resolution 1944 x 1944 video at 30 fps, the sensor requires just 126 mW, and supports ultra-low power mode to reduce power consumption to approximately 25 mW. Additionally, the OV2281 features optimized IR sensitivity to produce a clear, fully stable image in difficult, low-light conditions. The OV2281 sensor fits into a 5.5 x 5.5 mm module with a z-height of less than 4.5 mm. Find out more at www.ovt.com. Biometric Security for Next-Generation Smartphones, Tablets, and Notebooks OmniVision's OV2281 is a PureCel® sensor that brings enhanced biometric security functionality to mobile devices. The low-power, ultra-compact OV2281 leverages a 1.12-micron pixel with PureCel technology to enable accurate, reliable iris recognition for smartphones, tablets, and notebooks. The 1/7.5-inch OV2281 PureCel sensor can record 1080p high-definition (HD) video at 60 frames per second (fps) in both landscape and portrait modes to support apps with horizontal or vertical orientation.
