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.
