Surveillance camera reference design has auto-focus for object detection
Renesas Electronics and Novatek Microelectronics have collaborated on a surveillance camera reference design offering phase-detection auto-focus. It delivers fast and superior object detection and recognition for 4K video security and surveillance applications.
The ultra-high-definition (UHD) surveillance camera reference design addresses the high accuracy object detection and recognition needs of video security and surveillance systems. The reference design includes a camera image sensor (CIS) board with phase-detection auto focus (PDAF), and a high performance image signal processing (ISP) board and auto focus zoom lens software.
The surveillance camera reference design enables 4K resolution, excellent coluor imaging and better recognition accuracy of objects, including small objects in low-light conditions, claims Renesas. Its high speed auto focus operation can also be realized with low-priced lenses for a high performance 4K video security camera reference design and software that helps shorten the development time required in building a camera system with fast auto focus and enhanced imaging performance.
The reference design is built around Renesas’ high performance RAA462113FYL CMOS image sensor and Novatek’s dual core SoC image signal processor. 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.
The CMOS image sensor has high sensitivity, low noise, low power with high resolution 8M pixels. The sensor features HDR, PDAF functions and MIPI-CSI2 output, which support 30 frames per second at12-bit digital output.
The signal processor board includes an 800MHz dual core SoC image signal processor with sensor interface and interfaces for display, PHY, Wi-Fi module, GPS, and RS-485. There is also support for RTC, I2C, SPI, GPIO, audio IF, Flash/SD card, HDMI, Ethernet, SDIO, SCI, UART and an SDRAM controller.
Renesas developed the reference design in collaboration with Novatek Microelectronics and it was designed by, and is available from, Systemtec.
