1 Features and Specifications
1.1 Overview
The NVR delivers high performance within a networked security surveillance system. This series
of products also support local preview, multiple-window display, recorded file local storage,
remote control & mouse shortcut menu operation, and remote management & control function.
In addition to this it can also provide integral centre storage, front-end storage and client-end
storage. The monitor zone in the front-end can be setup anywhere. Working with other front-end
devices within the Qvis product range, this product series can establish a strong surveillance
network via the CMS. In order for the system to work you only need one network cable running
from each security camera, to the monitor workstation, within the whole network. There is no need
for multiple audio/video cables from the security cameras to the monitor workstation. The whole
project features a simple connection, which reduces network installation costs and a low amount
of maintenance work.
This series of NVRs can be widely used in many areas such as public security, water conservancy,
transportation and education.

Sending audio/video data, through the network, can both be compressed
by the IPC or the NVS and then sent to the monitoring station. The data
will then be decompressed and displayed. If the bandwidth is big enough,
latency will be less than 500miliseconds.
