1 Features

1.1 Overview

This series NVR is a high performance network video recorder. This series product supports local live

view, multiple-window display, recorded file local storage, remote control and mouse shortcut menu

operation, and remote management and control function.

This series product supports center 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 through the CMS. In the network

system, there is only one network cable from the monitor center to the monitor zone in the whole

network. There is no audio/video cable from the monitor center to the monitor zone. The whole

project is featured by simple connection, low-cost, low maintenance work.

This series NVR can be widely used in areas such as public security, water conservancy,

transportation and education.

1.2 Features

AI Functions

AI functions are available on select models and vary model to model. The actual product shall

prevail.

●Different models have different AI functions. The actual product shall prevail.

●Face detection. It includes front-end smart detection and back-end smart detection.

●Face recognition. It enables users to compare the detected faces with the images in the face

database in real time.

●Human body detection. System activates alarm actions once human body is detected.

●People counting. It can effectively count the number of people and flow direction.

●Heat map. It can monitor the active objects in a specific area.

●Automatic number plate recognition (ANPR). It can effectively monitor the passing vehicles.

Smart Playback

●IVS playback. It can screen out and replay the records meeting the set rules.

●Face detection playback. It can screen out and replay the records with human faces.

●Face recognition playback. It can compare the face information in the video with the information

in the database and replay the corresponding records.

●ANPR playback. It can screen out the record with a specific car plate number or all the records

with car plate numbers.

●Human body detection playback. It can screen out and replay the records with specific human

bodies.

●Smart search. It includes smart functions such as searching by attribute and searching by image

User's Manual

to enable users to get target records quickly.

Cloud Upgrade

For the NVR connected to the Internet, it supports application online upgrade.

Real-Time Surveillance

●VGA, HDMI port. Connect to monitor to realize real-time surveillance. Some series support

TV/VGA/HDMI output at the same time.

●Shortcut menu for preview.

●Support multiple popular PTZ decoder control protocols. Support preset, tour and pattern.

Playback

●Support independent real-time recording for each channel. At the same time it supports

functions such as smart search, forward play, network monitor, record search and download.

●Support various playback modes: slow play, fast play, backward play and frame-by-frame play.

●Support time title overlay so that you can view the event accurate occurred time.

●Support specified zone enlargement.

User Management

Users can be added to user groups for management. Each group has a set of permissions that can be

individually edited.

Storage

●With corresponding settings (such as alarm settings and schedule settings), you can back up

related audio/video data in the network video recorder.

●You can take records via the web and the record files are saved on the PC in which the client

locates.

Alarm

●Respond to external alarm simultaneously (within 200 ms). Based on user’s pre-defined relay

settings, the system can process the alarm input correctly and sends user screen or voice

prompts (supporting pre-recorded audio).

●Support settings of the central alarm server, so that the system can automatically notify users of

the alarm information. Alarm input can be derived from various connected peripheral devices.

●Alert you of alarm information via email.

Network Surveillance

●Send audio/video data compressed by IPC or NVS to client-ends through the network, and then

the data will be decompressed and displayed.

●Support max 128 connections at the same time.

●Transmit audio/video data by protocols such as HTTP, TCP, UDP, MULTICAST and RTP/RTCP.

●Transmit some alarm data or alarm info by SNMP.

●Support web access in WAN/LAN.

User's Manual
