Series Overview

Dahua NVR4000-4KS2/L is introduced as the 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 Profile S, T, G protocol, enabling interoperability with IP cameras. 

 Functions

1. Perimeter Protection by Camera
Automatically filtering out false alarms caused by animals, rustling
leaves, bright lights, etc. Enables system to act secondary recognition for
the targets. Improving alarm accuracy.

2. Face Detection by Camera
Face detection is to detect if there is any human face appearing in the
video. This technology adopts a deep learning algorithm to support face
detection, tracking, optimization and capturing, and then output the
best face snapshot. 

3. 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.

4. People Counting by Camera
With deep learning algorithm, Dahua People Counting technology
can track and process moving human body targets to realize the
accurate statistics of enter No., leave No., and In Area No. Working with
management platform, it outputs yearly/monthly/weekly/daily reports
to meet your requirements.

5. 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.

6. 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.
