Launched by Dahua Technology, WizSense is a series of AI products and
soluons that adopt independent AI chip and deep learning algorithm.

It focuses on human and vehicle with high accuracy, enabling users to

fast act on dened targets. Based on Dahua's advanced technologies,

WizSense provides intelligent, simple and inclusive products and

soluons.

System 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.

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.

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.

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.
