2.2.4 OmniVision Video Encoder OA7000

This design utilizes the OmniVision OA7000 to enable secured live video streaming with a resolution of up to 1080p at 48 FPS (1920 × 1080). It interfaces with an image sensor over mobile industry processor interface (MIPI). It also allows for low-power consumption, fast and secure boot up, and image processing for advanced video analytics. It has an integrated audio codec for high-quality audio with noise reduction and echo cancellation.

Refer to the OA7000 documentation for more details.
