System Overview
The X82B Series HDCVI DVR oers 4K recording on each HDCVI channel
and a host of advanced features and funcons. The X82B takes advantage
of HDCVI technology for easy integraon into exisng video surveillance
systems while leveraging exisng networks, cabling, and cameras.
Penta-brid access technology seamlessly records video from HDCVI,
AHD, TVI, CVBS, and IP sources simultaneously, plus the DVR delivers 4K
resoluon on each HDCVI or IP channel. This recorder is the ideal soluon
for acvely monitoring public venues, retail stores, transportaon hubs and
access ways, personal property and homes, and educaonal instuons.
Funcons
Perimeter Protecon
Dahua Analycs+ includes Tripwire and Intrusion funcons that oer
custom tripwires based on object type for automaon in limited access
areas. Perimeter Protecon requires less pixels to detect an object to
deliver improved accuracy and decreased false alarms due to lights,
weather, trees, or animals.
Smart Moon Detecon
The Smart Moon Detecon, a component of Dahua's Analycs+
technology, improves alarm accuracy and decreases the number of false
alarms. The advanced SMD algorithm analyzes a scene for human or
vehicle moon, while ltering out other moon due to trees, leaves,
animals, weather, and triggers an alarm when detected.
SMD
AI Coding
The AI Coding funcon puts recording emphasis on human or vehicular
objects in the video scene. This technology, based on constant bit
rate (CBR), dynamically allocates increased bit rate to the target
object while reducing the bit rate allocated to background objects. AI
Coding reduces bit rate and storage requirements by up to 50% when
compared to the H.265 video compression standard.
Smart H.265+
Smart H.265+ is the opmized implementaon of the H.265 codec that
uses a scene-adapve encoding strategy, dynamic GOP, dynamic ROI,
exible mul-frame reference structure and intelligent noise reducon
to deliver high-quality video without straining the network. Smart
H.265+ technology reduces bit rate and storage requirements by up to
90% when compared to the H.264 video compression standard.
4K Resoluon
The HDCVI DVR records 4K resoluon on each HDCVI and IP channel.
4K is a revoluonary breakthrough in image processing technology. 4K
delivers four mes the resoluon of standard HDTV 1080p cameras
and oers superior picture quality and image details. 4K resoluon
improves the clarity of a magnied scene to view or record crisp
forensic video from large areas.
HDCVI/AHD/TVI/CVBS Auto-detect
The HDCVI DVR automacally recognizes the incoming signals of each
aached camera without any setup, making installaon easy and
operaon convenient.
Long Distance Transmission
HDCVI technology guarantees real-me transmission over long
distances without loss of video quality. HDCVI devices provide the
same resoluon as most IP network camera systems using exisng
RG-59, RG-6, or CAT 6 UTP cabling.
