OmniVision Technologies has launched a 4Mpixel image sensor with a 2.0 micron pixel pitch for battery-powered IoT and home security cameras.

The OS04C10 supports an ultra low power mode for battery-powered cameras with AI functionality. Additionally, it provides high 2688 x 1520 resolution with a 16:9 aspect ratio, while adding the premium near-infrared (NIR) and ultra low light and high signal ratio by using the 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.

The Nyxel technology supports 850nm and 940nm NIR wavelengths with a high quantum efficiency. This QE enables the use of lower power IR illumination in total darkness, resulting in significantly reduced system-level power consumption.

“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. Additionally, these cameras are often battery-powered,” said Cheney Zhang, senior marketing manager for the security segment at OmniVision. “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.”

By combining OmniVision’s industry-leading NIR Nyxel technology with its PureCel Plus technology and multiple HDR options, the OS04C10 works equally well in all lighting conditions. It can detect incident light in both the visible and NIR wavelengths, while producing precise color and monochrome images for security applications.

Additionally, 940nm NIR lighting cannot be detected by the human eye in dark indoor settings, while 850nm light is ideal for outdoor security cameras. The OS04C10’s ability to capture images using undetectable 940nm NIR light means that indoor security cameras will not disturb sleeping occupants and can be easily concealed from intruders.

The OS04C10 is also built on
