DAHUA DHI-NVR4104HS-P-4KS2/L

4 Channel NVR with PoE

System Overview

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.

Functions

4K Resolution

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+

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.

DMSS

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

virtually anywhere!
