Dahua IPC-HDBW4231E-ASE 2MP Full HD WDR Network IR Mini Dome Camera

Dahua IPC-HDBW4231E-ASE 2MP Full HD WDR Network Vandal-proof IR Mini Dome ePoE Camera (2.8mm)

Dahua IPC-HDBW4231E-ASE Technical Specification
System Overview
With upgraded H.265 encoding technology, Eco-savvy series brings
high efficient video compression capability. It can save bandwidth and
storage. Meanwhile, the series features starlight, smart IR technology
and intelligent image analysis techniques. This series supports reminder
function, meanwhile fully protected from dust and water, certified to
IP67 and vandal resistant to IK10 standard.
Functions
ePoE technology
The ePoE technology of Dahua, designed internally, adopts advanced
2D-PAM3 coding modulation from physical layer, and realizes full duplex
transmission over 800 meters at the speed of 10Mbps, or 300 meters
at the speed of 100Mbps via Cat 5 or coaxial cable media. Besides,
it supports PoE and PoC power supply technology which has greatly
simplified construction and wiring. Dahua ePoE technology offer a new
way to accomplish long distance transmission between IP camera and
network switch. It allows more flexible surveillance system design,
improves reliability and saves construction and wiring cost.
Starlight Technology
For challenging low-light applications, Dahua’s Starlight Ultra-low Light
Technology offers best-in-class light sensitivity, capturing color details
in low light down to 0.002lux. The camera uses a set of optical features
to balance light throughout the scene, resulting in clear images in dark
environments.
Wide Dynamic Range(WDR)
The camera achieves vivid images, even in the most intense contrast
lighting conditions, using industry-leading wide dynamic range (WDR)
technology. For applications with both bright and low lighting conditions
that change quickly, true WDR (120 dB) optimizes both the bright and
dark areas of a scene at the same time to provide usable video.
Intelligent Video System (IVS)
IVS is a built-in video analytic algorithm that delivers intelligent functions
to monitor a scene for Tripwire violations, intrusion detection, and
abandoned or missing objects. A camera with IVS quickly and accurately
responds to monitoring events in a specific area. In addition to scene
analytics, the camera supports face detection to quickly capture a
face and upload the image to a server. The camera also offers tamper
detection by recognizing a dramatic scene change and generating a
warning message to inspect the camera.
Environmental
Dahua cameras operate in extreme temperature environments, rated for
use in temperatures from -30° C to +60° C (-22° F to +140° F) with 95%
humidity, allowing the camera to operate in the harshest environments.
Protection(IP67, IK10, wide voltage)
The camera allows for ±30% input voltage tolerance, suitable for the
most unstable conditions for outdoor applications. Its 6KV lightning
rating provides effective protection for both the camera and its structure
against lightning. Subjected and certified to rigorous dust and immersion
tests (IP67) and impact tests (IK10), the camera is the choice for
installation in even the most unforgiving environments.
Smart H.265+
Smart H.265+ is the optimized implementation of the H.265 codec that
uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI,
flexible multi-frame reference structure and intelligent noise reduction 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.
