■ 产品简介

IP Camera是一种把图像捕捉设备（摄像机）的图像转换成IP信号进行传输的设备，一般内置摄像机和视频压缩引擎。视频数据经H264格式压缩后，通过局域网，Internet或WIFI网络送至终端用户。用户可通过IE或客户端软件，进行视频的浏览访问和控制。

本方案基于升迈的GM812X系列多核SOC, （集成ARM9-CPU和H264图像编解码内核）

■ 功能特点

软件开发平台化，VGA-高清开发包架构高度统一，软件一次开发多款产品。

硬件高整合度，集成网卡，ISP；外围只需挂1个DDR，Flash，Senser
，大幅降低系统成本

硬件VGA 720P 1080p共板设计，应用全覆盖

图像增强技术3D-I & 3D-NR高品质的保障

低功耗，绿色环保

LQFP封装，4layer PCB设计，降低加工成本
