The network camera, also called IP CAMERA (referred to as IPC), is composed of a network coding module and an analog camera. The network coding module compresses the analog video signal collected by the analog camera into a digital signal, thereby directly accessing the network switching and routing device. The network camera has an embedded chip built in, using an embedded real-time operating system. Network cameras are a new generation of products combining traditional cameras with network video technology. The video signal transmitted by the camera is digitized and compressed by a high-efficiency compression chip and transmitted to the Web server through a network bus. Users on the network can directly view the camera image on the web server by using a browser, and the authorized user can also control the action of the camera pan/tilt lens or operate the system configuration. Network cameras can be more easily monitored, especially remote monitoring, simpler construction and maintenance, better audio support, better support for alarm linkage, more flexible video storage, richer product selection, and higher HD video effects,and more perfect monitoring management.
