The OS02H10 also offers multiple high dynamic range (HDR) options for the best quality 1080p still and video captures of fast-moving objects at 60 frames per second. Additionally, when paired with the designer’s selected platform, the OS02H10 can enable a system ultra-low-power mode for battery-powered cameras with AI functionality.
"Mainstream surveillance camera designers are looking for the ideal the combination of low power consumption and high performance over a wide range of lighting conditions, to enable AI algorithm recognition of faces and objects,” says Cheney Zhang, senior marketing manager for the security segment at OmniVision. “The OS02H10 provides a high value option for adding premium NIR, ultra low light and HDR performance to high volume, mainstream security systems with AI functionality, along with an ultra low power mode that consumes 97.7% less power than the normal mode to support long battery life."
By combining the company's NIR Nyxel technology with its PureCel Plus technology and multiple HDR options, the OS02H10 is designed to work 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.
The company's Nyxel technology provides exceptional quantum efficiency (QE), which enables the sensor to see better and farther at both the 850-nm and 940-nm NIR wavelengths. Such QE performance also enables the use of lower-power IR illumination in total darkness, resulting in significantly reduced system-level power consumption.
In addition, 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 OS02H10’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 PureCel Plus pixel architecture achieves a superior low-noise design, providing an SNR that is 70% better than the company's prior-generation 1080p, 2.8 micron mainstream security sensor. Additionally, says the company, the new sensor also offers excellent HDR through selective conversion gain for the optimum balance between low-light image quality and HDR, along with two-exposure staggered HDR timing for minimal artifacts. These features are designed to provide designers with maximum flexibility to select the best HDR method for the contrasting light and dark areas in a given scene.
Samples of the OS02H10 image sensor are available now.
