1 Features and Specifications
1.1 Overview
This series NVR is a high performance network video recorder. This series product support local preview,
multiple-window display, recorded file local storage, remote control and mouse shortcut menu operation,
and remote management and control function.
This series product supports centre storage, front-end storage and client-end storage. The monitor zone
in the front-end can be set in anywhere. Working with other front-end devices such as IPC, NVS, this
series product can establish a strong surveillance network via the CMS. In the network system, there is
only one network cable from the monitor centre to the monitor zone in the whole network. There is no
audio/video cable from the monitor centre to the monitor zone. The whole project is featuring of simple
connection, low-cost, low maintenance work.
This series NVR can be widely used in many areas such as public security, water conservancy,
transportation and education.
