Overview

The OV4685 is a high performance 4-megapixel CameraChip™ sensor in a native high definition (HD) 16:9 format designed for next-generation surveillance and security systems. The sensor is built on a 2-micron OmniBSI-2™ pixel that provides best-in-class sensitivity, and uses advanced OmniHDR-F™ technology to provide industry leading staggered high dynamic range (HDR).

The 1/3-inch OV4685 can capture full-resolution 4-megapixel HD video at 90 frames per second (fps), 1080p HD at 120 fps, and binned 720p HD at 180 fps. The sensor's high frame rates enable crisp, clean image and video capture of fast moving objects.

The OV4685's advanced OmniHDR-F technology provides staggered HDR timing, increasing dynamic range to 64.6 dB while recording high-quality images and video under extreme variations of bright and dark conditions.

The sensor features a high-speed 4-lane MIPI serial output interface to facilitate the required high data transfer rate. The OV4685 is available in a chip scale package (CSP).
