Overview

OmniVision's OA805 is a video processor that supports high-efficiency video coding (HEVC) compression with the lowest power consumption in the industry. This advanced video compression standard reduces storage requirements and enables the streaming of 4K videos over wireless connections. The OA805 is extremely power efficient, and is making HEVC possible for battery-powered security cameras and video doorbells for the first time. Together with the industry's fastest boot-up time of 0.1 seconds, the OA805 allows designers to incorporate leading-edge performance into products that their customers can quickly and easily install anywhere, and never miss a thing. Furthermore, because the processor consumes no power when it is off, the overall power consumption of the security camera is extremely low and allows the camera to have up to two years of battery life.

The OA805 is a system-on-chip (SoC) featuring dual embedded Arm® Cortex®-A5 CPU cores with Neon™ technology for accelerated audio and video encoding/decoding, along with image processing, video encoding hardware and RGB/IR processing. Its high dynamic range (HDR) processing capability allows the OA805 to accept input from RBG/IR image sensors and support high-quality displays, for videos taken during the day or at night, in conditions with widely contrasting bright and dark images.

This video processor accepts up to 16-megapixel captures from an image sensor and outputs up to 4K resolution video at 30 frames per second (fps) using HEVC encoding and decoding. It also supports multiple video streams at lower resolution, including H.264 1080p resolution at 60 fps, as well as HDR and RGB-IR.
