Surveillance Camera with CMOS Sensor Reference Design

The solution demonstrates a CMOS image sensor (CIS) board with phase-detection autofocus (PDAF) and a high-performance image signal processing (ISP) board along with autofocus zoom lens software. Using this reference design, users can evaluate the autofocus functionality of the CN251-RAA462113EVZ Surveillance Camera Module.

The reference design enables 4K resolution, excellent color imaging, and better recognition accuracy of objects, including small objects in low-light conditions. Its impressive high-speed autofocus operation can also be realized with low-priced lenses. Built around Renesas’ high-performance RAA462113FYL CMOS image sensor and Novatek’s dual-core system-on-chip (SoC) image signal processor, the surveillance camera reference design uses several other Renesas ICs that address its signal chain electrical functions. The CIS board includes the RAA462113FYL, DC/DC buck converters, LDOs, motor driver, and lens. The ISP board features the SoC and associated signal chain components.
