Series Overview

Dahua new NVR4000-I network video recorder delivers excellent
performance and high recording quality that is ideally suitable for IP

video surveillance applicaons. This NVR adopts powerful processor,
providing the capability of 4K resoluon processing for applicaons

where image details are highly required. Besides, the NVR supports

input, recording and transmission funcons. Addionally, the NVR can

be served as edge storage, central storage or backup storage with an

intuive shortcut operaon menu for remote management and control.

With build-in deep learning module, NVR4000-I series products adopt
video image structuring technology based on deep learning algorithms,

achieving high-precision human face recognion and perimeter
protecon. By applying deep learning arcial intelligence, NVR4000-I
allows users to focus on what maers most, improves event response
me and helps make video aconable.

The NVR is compable with numerous third-party devices, which make it
the perfect soluon for surveillance systems that work independently of
video management system (VMS).

Funcons

Perimeter Protecon

Automacally ltering out false alarms caused by animals, rustling
leaves, bright lights, etc. Enables system to act secondary recognion for

the targets. Improving alarm accuracy.

Face Recognion

Dahua Face Recognion technology extracts the features of captured

faces and compares them with that in face database to recognize the

person identy.

SMD Plus

With intelligent algorithm, Dahua Smart Moon Detecon technology can
categorize the targets that trigger moon detecon and lter the moon
detecon alarm triggered by non-concerned targets to realize eecve and

accurate alarm.

ANPR by Camera

With deep learning algorithm, Dahua ANPR technology can recognize the
number plate informaon of vehicles in the image with ANPR cameras.

Support block/allowlist mode, searching target vehicles from recorded
video.

Fisheye Dewarping

Fisheye dewarping solves the problem of distoron in the circular
panoramic view. The device oers various dewarping modes for dierent
installaons and conguraons that enhance the video, in both live or
playback modes. Each dewarping mode oers opons to adjust each

scene.

People Counng by Camera

With deep learning algorithm, Dahua People Counng technology

can track and process moving human body targets to realize the

accurate stascs of enter No., leave No., and In Area No. Working with
management plaorm, it outputs yearly/monthly/weekly/daily reports to

meet your requirements.

DMSS

The DMSS app is available on the iOS App Store and Google Play. It makes

surveillance easy and simple, allowing you to remotely access back-end

devices, view live video, receive event push nocaons, and search for
recorded videos from an iPhone, iPad, or Android phone at anyme from

virtually anywhere.
