Based on PoE's IP-Camera FIC8120 and design (1)

Introduction

In today's digital era of the Internet, any electronic equipment are efforts to digitize and network development.

The network is closer to us, the network is changing our lives. Monitoring fields also unhesitatingly rapid development towards networking, in which the camera's networking development also overwhelming. [6] IP camera enables remote video surveillance possible, it will change the original distributed simulation of the camera to achieve low cost long distance transmission of a predicament!

To meet the distributed single camera distance transmission needs, modern IP camera must have small bandwidth, high-quality, low cost, low power consumption characteristics.

This system uses digital CMOS Digital imaging sensors, MPEG-4 high compression ratio of VGA/CIF ARM-SoC and Si3401 over Ethernet and Ethernet device controller and the digital real-time network camera solution to meet the present and the future of monitoring requirements.

Overall hardware architecture

The entire system by CMOS video capture, compression, video processing, power over Ethernet and Ethernet data communication, and several parts.

From front-to back-end order after "lens OV7660 → FIC8120-SoC → PoE/Network" and several processing.

According to your requirement, we can choose the appropriate lens group, from the lens Gets the impersonation information is carried out by OV7660 digital capture by the CMOS sensor delivered to subsequent processing component.

FIC8120-SoC related design

FIC8120 is a famous UMC serves under somebody's banner the FARADAY Zhiyuan technology to design a highly integrated, with MPEG4/JPEG video acceleration, low-cost, low power consumption, the SoC ARM922 kernel.

FIC8120 as system CPU, capture OV7660 [5] output of ITU 656 YUV 4: 2: 2 VGA format digital image signals, and through the AHB DMA to external SDRAM.

At the same time, the transfer-encoding of internal MPEG-4 Codec. Complete coding, after the user selected related processing, send to the output from the ports Ethernet MAC. [1] [2] [3] [4]
