OmniVision OA805 4K Video Camera SoC Supports 100 ms Boot Time, 4K HEVC Encoding

OmniVision OA805 Arm Cortex-A5 4K video camera processor is specifically designed for battery operated security and surveillance cameras, including video doorbells, with the ability to encode 4K30p video streams with HEVC/H.265 video codec at very low power consumption.

The processor also has a very short boot-up time of just 100ms, meaning it can go from completely powered off to fully functional upon trigger by a motion detection sensor. That short boot time removes the need for standby or sleep mode further lowering the power consumption and allowing the camera to have up to two years of battery life (albeit no mention of battery capacity was made…).

There’s no information about software support, but I’d assume the company provides a Linux SDK for the chip, and does offer an evaluation kit.

OmniVision OA805 video processor is said to be available, with limited information on the product page, but if you happen to be at CES 2020, you can inquire about the solution at the company’s CES hotel suite until January 10.
