Internet of Things (IoT) Support
The HDCVI DVR integrates with HDCVI IoT devices to support 
mul-dimensional surveillance. This device records sensor data as 
well as the video from HDCVI IoT devices and can generate a detailed 
report based on the data. 
Spot Output
The HDCVI DVR provides a spot output channel for a secondary 
monitor. This monitor allows the operator to view one monitor that is 
assigned to selected cameras or video inputs from high-security areas. 
Point of Sale (POS) 
Ideal for grocery and retail stores, the oponal POS soluon allows the 
HDCVI DVR to receive a POS transacon via corresponding video. This 
feature allows merchants to analyze specic transacons via the Fuzzy 
Search Algorithm.
Smart Fan Design
The HDCVI DVR automacally turns on or turns o the fan according 
to the CPU temperature. This funcon reduces fan noise and helps to 
conserve electricity.
Intelligent Video System (IVS)
IVS is a built-in video analyc algorithm that delivers standard 
intelligent funcons to monitor a scene for Tripwire violaons, 
intrusion detecon, and abandoned or missing objects. IVS quickly and 
accurately responds to monitoring events in a specic area. 
Face Detecon
This technology idenes human faces in digital images and then 
searches a database to idenfy the individual in the image. 
Smart Search
Smart Search allows an operator to specify a region in the playback 
video to search for a moon detecon event, saving me and 
manpower.
System Overview
The X72A Series HDCVI DVR oers 4K recording on each HDCVI channel 
and a host of advanced features and funcons. The X72A 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 on each channel.
The X72A ulizes the Smart H.265+ Codec to signicantly improve encoding 
eciency and to reduce bandwidth and storage costs. In addion to 
the advanced codec, the X72A series supports Internet of Things (IoT) 
funconality and Point of Sale (PoS) integraon. This recorder is the 
ideal soluon for acvely monitoring and recording video feeds in a wide 
range of applicaons including public venues, retail stores, transportaon 
hubs and access ways, personal property and homes, and educaonal 
instuons.
Funcons
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.
