1. Kokia yra Dahua kameros vaizdo raiška ir kadrų dažnis?

Dahua Technology 4MP IP kameros vaizdo kokybė yra 4 megapikselių, o maksimali rezoliucija siekia 2688 x 1520 taškus. Aukštos raiškos vaizdo perdavimo sparta yra 30 kadrų per sekundę (30 fps), kas užtikrina sklandų ir detalių vaizdą realiuoju laiku, tinkantį tiksliam stebėjimui.

2. Ar šį prietaisą galima montuoti lauke?

Taip, ši apsaugos kamera tinka montavimui lauke. Įrenginio apsaugos klasė IP67 apsaugo nuo dulkių ir trumpalaikio panardinimo į vandenį, todėl jis atlaiko sudėtingas oro sąlygas. Prietaisas veikia patikimai tiek patalpose, tiek atviroje erdvėje.

3. Kokį matymo lauką ir naktinį matymą turi šis modelis?

Kamera pasižymi 360 laipsnių panoraminio sukimosi galimybe. Naktinio režimo nuotolis siekia iki 50 metrų, o minimalus apšvietimas yra vos 0,002 liukso, todėl ryškų vaizdą užtikrina net visiškai tamsoje. Ši stebėjimo sistema efektyviai veikia paros metu.

4. Kaip prietaisas maitinamas ir jungiasi prie tinklo?

Maitinimo šaltinis yra DC arba Power over Ethernet (PoE). Ryšys su tinklu palaikomas per Ethernet LAN laidinį jungtį. Šis maitinimo būdas supaprastina instaliaciją, nes reikia tik vieno kabelio duomenims ir energijai tiekti, sutaupant laiko.

5. Kokias papildomas funkcijas turi šis stebėjimo įrenginys?

Įrenginys turi įmontuotą mikrofoną garso fiksavimui ir platus dinaminis diapazonas (WDR), pagerintą vaizdą stipriai apšviestose arba tamsiose vietose. Taip pat aktyvuojamas triukšmo mažinimas, kuris pagerina signalo kokybę. Automatinis balansavimas palaiko natūralias spalvas.

Aprašymas

Pro AI series contains Face Detection, Perimeter Protection and People
Counting functions.Powered by deep-learning Artificial Intelligence algo-
rithms, significantly improved accuracy. Meanwhile, the series features
starlight and smart IR technology. This series fully protected from dust
and water, certified to IP67 standard.

Face Detection
Face Detection is a software application that automatically captures
faces from within a digital image or a video frame from a video source.
Dahua cameras use advanced deep learning algorithms and are trained
by a large number of face data sources, enabling the camera to locate
faces quickly and accurately from the video source and capture facial
images.

Perimeter Protection
Dahua’s Perimeter Protection functions significantly improved accu-
racy. Perimeter Protection reduces false alarms and decreases pixel
count requirements for object detection. Perimeter Protection features
custom tripwires based on object type for automation in limited access
areas such as pedestrian or vehicle-only zones. This combination of
advanced AI analytics and real-time alerts to a desktop or to a mobile
client reduces system requirements and resources resulting in greater
surveillance system efficiency.

People Counting
People Counting function uses advanced image processing technology
to capture depth information from within images. The camera pairs this
information with deep learning algorithms to analyze and detect human
bodies and track target objects in real time. The camera provides statis-
tics for separate individuals’ entrance and exit with up to 95% counting
accuracy.

Protection(IP67, wide voltage)
The camera allows for ±30% input voltage tolerance, suitable for the
most unstable conditions for outdoor applications. Its 6KV lightning rat-
ing provides effective protection for both the camera and its structure
against lightning. Subjected and certified to rigorous dust and immer-
sion tests (IP67) , the camera is the choice for installation in even the
most unforgiving environmen
