8MP 40x Starlight IR PTZ AI Network Camera

Launched by Dahua Technology, Dahua WizMind is a full
porolio of soluons composed of project-oriented products
including IPC, NVR, PTZ, XVR, Thermal and soware plaorm

which adopts industry-leading deep learning algorithms.

Focusing on customer's requirements, WizMind provides
precise, reliable and comprehensive AI soluons for industry
vercals.

System Overview

Dahua PTZ WizMind network camera adopts advanced CNN deep

learning algorithms to support face recognion with high accuracy.

This camera possess wide monitor range, PFA algorithm that can
always present a clear, focused image while zooming, and smart wiper
technology that supported by RainSensor.

Funcons

Starlight Technology

For challenging low-light applicaons, Dahua's Starlight Ultra-low Light
Technology oers best-in-class light sensivity, capturing color details in
low light down to 0.005 Lux. The camera uses a set of opcal features
to balance light throughout the scene, resulng in clear images in dark

environments.

Face Recognion

Once facial features are extracted from captured faces, they are stored
in a database where they can be easily searched and compared against
other images. Once a successful match is found, the system outputs the

result. The Dahua Face Recognion camera supports a built-in database

that stores up to 10,000 facial images, helping the camera achieve real-

me face capture and comparison.

Auto-tracking

This feature controls the pan/lt/zoom acons of the camera to
automacally track an object in moon and to keep it in the scene. The
tracking acon can be triggered manually or automacally by dened

rules. Once a rule is triggered, the camera can zoom in and track the

dened target automacally.

Perimeter Protecon

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

targets. Improves alarm accuracy.

Metadata

Metadata is aribute informaon extracted from a target which can be

used for data retrieval. There are four kinds of metadata supported by
Dahua PTZ WizMind camera: Human face, human body, motor vehicle

and non-motor vehicle. Facial informaon includes gender, age, glasses,
masks, beards, etc. Human body informaon includes hat, top, top color,
boom, boom color, bag, etc. Motor vehicle informaon includes plate

color, type, vehicle color, sunshield, ornament, calling, seatbelt, smoking,

annual inspecon scker, etc. Non-motor vehicle informaon includes

type, color, top type, top color, people number, etc.

PFA Technology

PFA technology has innovavely introduced new methods of judgment
to ensure the accuracy and predictability of the direcon of subject
distance adjustment. The result is a set of advanced focusing algorithms.

PFA ensures clarity of the image throughout the process of zooming

and shortens focus me. The realizaon of PFA technology substanally

improves user experience and increases product value.

Smart H.265+

Smart H.265+ is the opmized implementaon of the H.265 codec that
uses a scene-adapve encoding strategy, dynamic GOP, dynamic ROI,
exible mul-frame reference structure and intelligent noise reducon

to deliver high-quality video without straining the network. Smart
H.265+ technology reduces bit rate and storage requirements by up to
70% when compared to standard H.265 video compression.
