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.

Preview Configuration
Each preview window links to a camera, and by default, the first window links to camera D1, the
second window links to camera D2, and so on (see the figure below).
You may drag a window to the desired position on the screen so the window links to the camera that
the previous window links to and then check the link under System > Preview. You may also refer to
the following example, which describes how to link window 1 to D2, and link window 2 to D1.
Step 1: Click window 1 on the right, and then click D2 under Camera on the left. Now D2 appears in
window 1, and None appears in window 2. Meanwhile, D1 is grayed out on the left, meaning D1 is
not linked to any window.
Step 2: Click window 2 on the right, and then click D1 under Camera on the left. Now D1 appears in
window 2. Click Apply to save the settings.
