Series Overview

Dahua NVR2000-4KS2 is capable of transmitting 8MP image. It helps 
to save up to 50% HDD and storage space with its H.265 decoding 
technology compared with H.264.
Due to its cost-effective and easy-to-install design, this NVR is ideal for 
a wide range of applications such as home safety, grocery, warehouse, 
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

1.SMD Plus by Camera
With intelligent algorithm, Dahua Smart Motion Detection technology can 
categorize the targets that trigger motion detection and filter the motion 
detection alarm triggered by non-concerned targets to realize effective and 
accurate alarm.

2. 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.

3. Smart Codec
With advanced scene-adaptive rate control algorithm, Dahua smart codec 
technology realizes the higher encoding efficiency than H.265 and H.264, 
provides high-quality video, and reduces the cost of storage and transmission.

4. ANR (Automatic Network Replenishment Technology)
Video record in SD card in IP cameras when the network breaks down, and 
after the network recovered, the video will be transferred to device and then 
recorded in it.

5. 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 back-end 
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.
