DAHUA 8 Channel Compact 1U 4PoE 4K&H.265 Lite Network Video Recorder DHI-NVR4108HS-8P-4KS2
Dahua NVR4000-4KS2 is introduced as the first Lite series NVR
that supports for 4K and H.265 encoding technology with excellent
performance at an affordable price. For applications where image
details are highly required, it delivers the capability of 4K resolution
processing. The NVR can be served as edge storage, central storage or
backup storage with an intuitive shortcut operation menu for remote
management and control.
Due to its cost-effective and easy-to-install design, this NVR is ideal for
a wide range of applications such as public safety, water conservancy,
transportation, city centers, education, and financial institutions.
The NVR is compatible with numerous third-party devices making it
the perfect solution for surveillance systems that work independently
of video management system (VMS). It features an open architecture
that supports for multi-user access and is compatible with ONVIF 2.4
protocol, enabling interoperability with IP cameras.
4K resolution is a revolutionary breakthrough in image processing
technology. 4K delivers four times the resolution of standard HDTV
1080p cameras and offers superior picture quality and image details. 4K
resolution improves the clarity of a magnified scene to view or record
crisp forensic video from large areas.
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.
Intelligent Video System
Working with IVS-enabled IP cameras, the NVR recognizes and records
video that contains IVS data on all IP channels. The NVR records standard
intelligence at-the-edge features, as well as premium IVS features that
detect abandoned or missing objects, Tripwire violations, and intrusion
violations. The NVR is also capable of recording business analysis data –
Facial Detection, People Counting, and Heat Map – from IP cameras with
built-in Intelligent Business Analytics.
ANR (Automatic Network Replenishment Technology)
Network Video Recorders with the ANR function automatically store
video data on an IP camera SD card when the network is disconnected.
After recovery of the network, the NVR automatically retrieves the video
data stored on the camera.
The DMSS app is available on the iOS App Store and Google Play. It
makes surveillance easy and simple, allowing you to remotely access NVR
devices, view live video, receive event push notifications, and search for
recorded videos from an iPhone, iPad, or Android phone at anytime from
