Server / Client Architecture
NVR 3.0 is a typical web-based server/client system. In a video surveillance system
architecture, the Server serves as a video management service provider, aimed to run 24/7
offering non-stop services for clients. A Client makes requests of monitoring video streams or
playback recordings to Server, which can reside on the same computer with server program
(as from local) or on another computer (as from remote). Server starts automatically as soon
as the Server computer (where it is installed) boots up, and operates in the background
without requiring login by administrator. It would provide services over the TCP/IP network to
multiple Clients upon request through HTTP Protocol.
There are two types of Clients in NVR 3.0 system: Web Client and Workstation Client. A
user, connecting from whether web browser or workstation, will enjoy the same user interface
and NVR functions.
 Web Client: the web version of interface to access the NVR server without need of installing
any client program to become a client. Logging in the NVR server is as simple as visiting a
website through IE browser.
 Workstation Client: the client application accessing the NVR server free from the use of
browser .The workstation includes a set of programs that provide interface between users
and the NVR server.
