Preface
This manual describes how to use your NVR locally or on the Web interface.
In this manual, the terms IP camera and IPC refer to the same thing: network camera, which requires
a connection to the network. And the IP device mentioned in this manual refers to an IP camera (also
known as network camera) or a Digital Video Server (DVS).
Part I Local Operations
An NVR supports two types of operations: local operations and web-based remote operations. With
local operations you connect a monitor and a mouse to the NVR and use the mouse to operate. If
your NVR has buttons on the front panel or is delivered with a remote control, you may also control
your NVR by pressing the front panel buttons or using the remote control.
The NVR has an embedded web server and allows web-based operations. To do this, you need a
client PC that has a network connection to the NVR and is installed with a web browser. You just
need to navigate to the NVR's IP address and log in to the Web interface like you log in to the system
locally.
This section describes local operations.
