1 Features and Specifications
1.1 Overview
This NVR is a high performance network video recorder. This product supports local preview, multiple-
window display, recorded file local storage, remote control, mouse shortcut menu operation, remote
management and control function.
This series product supports central storage, front-end storage and client-end storage. The monitoring
zone in the front-end can be set anywhere. Working with other front-end devices such as IP cameras or
an NVS, this product can establish a strong surveillance network via the VMS. In the whole network, there
is only one network cable from the monitoring centre to the monitoring zone. Furthermore, there is no
audio/video cable from the monitoring centre to the monitoring zone. The whole project features a simple
connection and low-cost, low maintenance work.
This NVR can be widely used in many areas, such as in public security, water conservancy, transportation
and education.
1.2 Features
Real-Time
Surveillance
VGA and HDMI ports. Connect to the monitor to realize real-time surveillance.
Some products support simultaneous TV/VGA/HDMI output.
Short-cut menu when in preview mode.
Supports popular PTZ decoder control protocols. Supports presets, tours and
patterns.
Playback
Independently supports each channel’s real-time recording and simultaneously
supports functions like: search, forward play, network monitor, record search,
download and etc.
Supports various playback modes: slow play, fast play, backward play and frame
by frame play.
Supports time title overlay so that you can view the accurate time of when the
event occurred.
Supports specified zone enlargement.
User
Management
Each grouphas differentmanagementpowers that can freely beedited. Everyuser
belongs to an exclusive group.
Storage
You canbackup related audio or video datein the NVR via the corresponding setup
(such as alarm setup and schedule setup).

2
Supports Web recording, local video recording and storage of the file in the client
end.
Alarm
Responds to external alarms simultaneously (within 200MS) according to the
user’s predefined relay setup. The system can process the alarm input correctly
and prompt the user via the screen and voice (supports pre-recorded audio).

and remotely notify the user. The alarm input can be derived from various
connected peripheral devices.
Alerts you via email/SMS.
Network
Monitoring
Sends audio/video data compressed by the IP cameras or NVS to client-end
through the network. The data is then decompressed and displayed.
Supports a maximum of 128 connections at the same time.
Transmits audio/video data by HTTP, TCP, UDP, MULTICAST, RTP/RTCP, etc.
Transmits some alarm data or alarm info by SNMP.
Supports WEB access in WAN/LAN.
Window
Splitting
Supports video compression and digital process to show several windows on one
monitor. Supports 1/4/8/9/16/25/36 window display when in preview mode and
1/4/9/16 window display when in playback mode.
Recording
Supports the following recording functions: normal/motion detection/alarm.
Saves the recorded files on the HDD, the USB device, the client-end P or the
network storage server. You can search or playback the saved files on the local-
end or via the Web/USB device.
Backup
Supports network backup and USB2.0 recordings backup functions. The recorded
files can be saved on the network storage server, a peripheral USB2.0 device, a
burner, etc.
Network
Management
Supervises the NVR configuration and controls the power via Ethernet.
