Overview

OmniVision's OA7000 video processor, building on the success of its predecessor, the OV798, provides a more cost effective solution for battery powered intrusion cameras and video doorbells. It includes industry leading technologies for low power consumption and fast boot-up. When paired with OmniVision's unique and sophisticated RGB-Ir sensors, it eliminates the need for a mechanical IR cut filter, which further optimizes the camera size and enhances system reliability.

Additional improvements include a triple-core ARM® Cortex® A5 CPU with NEON® support. This high-performance processor enables more advanced video analytics algorithms to be done on-chip, which reduces false alarms and increases battery life. Thanks to the powerful processor and integrated audio CODEC, high quality audio with noise reduction and echo cancellation is now available without extra cost.

A newly redesigned and more power efficient high dynamic range (HDR) ISP with RGB-Ir support is available on the OA7000. Combining the benefits of RGB-Ir and HDR, it shows every detail of the most challenging scenes with widely contrasting dark and bright areas, which are commonly found in video doorbell footage.

As cybersecurity becomes increasingly important, the OA7000 provides security features for secured boot up and live streaming.
