本嵌入式網絡攝像機采用高性能ARM9 芯片微處理器，內置嵌入式Web 服務器。通過
嵌入式多任務操作系統(tǒng)采集攝像機視頻數據；采集的視頻信號數字化后經MJPEG 算法壓縮，再通過內部總線送到內置的Web 服務器；使用者可以直接用瀏覽器觀看Web 服務器上的攝像機圖像；通過通用網關接口CGI，授權用戶還可以控制攝像機、云臺和鏡頭的動作或直接通過Web 頁面對系統(tǒng)進行配置。

Abstract: This embedded web camera takes the powerful ARM9 chip as MPU，there is
a embedded web server inside it. The camera captures the video through embedded
multitask operating system；the digital video has been compressed by MJPEG algorithm
before it is sent to inner web server through interior bus；the users can view
camera’s video directly by internet explorer and the users who are authorized can
also control camera、the motion of cloud-station and lens or configure the parameters
of the embedded web camera straightly by Common Gateway Interface.
