System Overview
Dahua's Pro Series network video recorders oer excellent performance
and high recording quality for IP video surveillance applicaons. For
applicaons where details are crical for idencaon, this professional
NVR provides a powerful processor with up to 4K resoluon. Addionally,
the NVR features a mouse shortcut operaon menu, remote
management and control, center storage, edge storage, and back up
storage.
Designed as a cost-eecve and easy to install recorder, this NVR is
an ideal addion to any security system that monitors public spaces,
water conservancy, transportaon, city centers, schools, and nancial
instuons.
The NVR is compable with numerous third-party devices making it
the perfect soluon for surveillance systems with or without a video
management system (VMS). Its open architecture supports mul-user
access and it is compable with ONVIF 2.4, enabling interoperability
when combined with 4K cameras.
Funcons
Dewarping Mode
The NVR has the ability to correct the distoron in a circular panoramic
view produces by a sheye lens. The NVR oers various dewarping
modes for dierent installaons and conguraons.
N+M Hot Standby
The highly reliable N+M Hot Standby redundancy design provides a
secure, fail-over technique ensuring immediate backup. In the event of a
system failure, the slave instantly takes over the master ensuring no data
is lost.
4K Resoluon
4K resoluon is a revoluonary breakthrough in image processing
technology. 4K delivers four mes the resoluon of standard HDTV
1080p devices 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.
Intelligent Video System (IVS) Recording
With built-in intelligent video analycs, the NVR has the ability to detect
and analyze moving objects for improved video surveillance. The NVR
provides standard intelligence at the edge allowing detecon of mulple
object behaviors such as abandoned or missing objects. IVS also supports
Tripwire analycs, allowing the camera to detect when a pre-determined
line has been crossed, People Counng, ideal for business intelligence,
and Facial Detecon, for searching or idencaon of individuals.
Face Recognion
The NVR stores face recognion video and data from a dedicated facial
recognion camera connected to the NVR. The NVR triggers an event if
the recognion database on the camera detects a face match.
Heat Map
The Heat Map opon highlights the areas with the highest concentraon
of people. This informaon can then be exported into a customized
report to assist in business or forensic analysis.
Automac Network Replenishment Technology (ANR)
Network Video Recorders with the ANR funcon automacally store
video data on an IP camera SD card when the network is disconnected.
Aer recovery of the network, the NVR automacally retrieves the video
data stored on the camera.
Automac License Plate Capture
The NVR automacally captures and stores vehicle license plate images
from a dedicated license plate capture camera connected to the NVR.
During playback, an operator can perform a license plate search by
Time and Date to view thumbnail images of all plates captured during
the specied me period. License plate capture technology oers
eecve entrance/exit management, trac surveillance, and parking lot
monitoring.¹
