OmniVision Technologies has announced what it claims is a best-in-class 2.0 micron pixel, 4 megapixel (MP) resolution image sensor for both IoT and home security cameras. When paired with the designer’s selected platform, says the company, the OS04C10 can enable a system ultra low power mode for battery-powered cameras with AI functionality. In addition, it provides high 2688 x 1520 resolution with a 16:9 aspect ratio, while adding near-infrared (NIR) and ultra low light, SNR1 performance of the company’s Nyxel and PureCel Plus technologies.

The sensor also offers multiple high dynamic range (HDR) options for the highest quality 4MP still and video captures of fast-moving objects at 60 frames per second.

“AI-enabled IoT and home security cameras require excellent performance across all lighting conditions for accurate algorithm detection of faces, license plates and other items,” says Cheney Zhang, senior marketing manager for the security segment at OmniVision. “Additionally, these cameras are often battery-powered. The OS04C10 maintains the same high 4MP resolution as our popular OV4689 sensor, while adding improved NIR, ultra low light and HDR performance for these IoT and home security cameras, along with a new ultra low power mode that consumes 98.9% less power than the normal mode for longer battery life.”

The OS04C10 image sensor, says the company, works equally well in all lighting conditions, and can detect incident light in both the visible and NIR wavelengths, while producing precise color and monochrome images for security applications. The company’s Nyxel technology provides the OS04C10 with exceptional quantum efficiency (QE), which enables it to see better and farther at both the 850-nm and 940-nm NIR wavelengths.

The device’s QE performance also enables the use of lower power IR illumination in total darkness, resulting in significantly reduced system-level power consumption. Additionally, 940-nm NIR lighting cannot be detected by the human eye in dark indoor settings, while 850-nm light is ideal for outdoor security cameras. The OS04C10’s ability to capture crisp, clear images using undetectable 940-nm NIR light means that indoor security cameras will not disturb sleeping occupants and can be easily concealed from intruders.

The company’s PureCel Plus pixel architecture enables the OS04C10 to achieve a superior low-noise design, providing an SNR1 that is 150% better than the company’s prior-generation OV4689 4-MP mainstream security sensor. Additionally, the new sensor is offered as having excellent HDR through selective conversion gain for the optimum balance between low light image quality and HDR, along with 2-exposure staggered HDR timing for minimal artifacts, providing designers with maximum flexibility to select the best HDR method for the contrasting light and dark areas in a given scene.

The OS04C10 image sensor is available now for sampling and mass production, in color and monochrome versions.
