System Overview

The X72A Series HDCVI DVR oers 4K recording on each HDCVI channel
and a host of advanced features and funcons. The X72A takes advantage
of HDCVI technology for easy integraon into exisng video surveillance
systems while leveraging exisng networks, cabling, and cameras.

Penta-brid access technology seamlessly records video from HDCVI, AHD,

TVI, CVBS, and IP sources simultaneously at 4K resoluon on each channel.

The X72A ulizes the Smart H.265+ Codec to signicantly improve encoding
eciency and to reduce bandwidth and storage costs. In addion to

the advanced codec, the X72A series supports Internet of Things (IoT)

funconality and Point of Sale (PoS) integraon. This recorder is the
ideal soluon for acvely monitoring and recording video feeds in a wide
range of applicaons including public venues, retail stores, transportaon
hubs and access ways, personal property and homes, and educaonal
instuons.

Funcons

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 90% when
compared to the H.264 video compression standard.

4K Resoluon

The HDCVI DVR records 4K resoluon on each HDCVI and IP channel. 4K is
a revoluonary breakthrough in image processing technology. 4K delivers
four mes the resoluon of standard HDTV 1080p cameras and oers
superior picture quality and image details. 4K resoluon improves the
clarity of a magnied scene to view or record crisp forensic video from

large areas.

HDCVI/AHD/TVI/CVBS Auto-detect

The HDCVI DVR automacally recognizes the incoming signals of each
aached camera without any setup, making installaon easy and operaon

convenient.

Series

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 oponal POS soluon allows the
HDCVI DVR to receive a POS transacon via corresponding video. This
feature allows merchants to analyze specic transacons via the Fuzzy

Search Algorithm.

Smart Fan Design

The HDCVI DVR automacally turns on or turns o the fan according
to the CPU temperature. This funcon reduces fan noise and helps to

conserve electricity.

Intelligent Video System (IVS)

IVS is a built-in video analyc algorithm that delivers standard
intelligent funcons to monitor a scene for Tripwire violaons,
intrusion detecon, and abandoned or missing objects. IVS quickly and
accurately responds to monitoring events in a specic area.

Face Detecon

This technology idenes human faces in digital images and then
searches a database to idenfy the individual in the image.

Smart Search

Smart Search allows an operator to specify a region in the playback
video to search for a moon detecon event, saving me and

manpower.
