DAHUA 8CH COMPACT POE IP NVR

The Dahua NVR4000-4KS2/L is the perfect solution for surveillance systems that require high image details and top-of-the-line performance at an affordable price.

With 4K resolution processing and H.265 encoding technology, this Lite series NVR is a cost-effective and easy-to-install choice for public safety, water conservancy, transportation, city centers, education, and financial institutions. Whether used as edge storage, central storage, or backup storage, the NVR can be managed and controlled remotely via an intuitive shortcut operation menu.

It also boasts an open architecture that supports multi-user access and is compatible with ONVIF Profile S, T, G protocol for seamless integration with various third-party devices. Choose Dahua for superior surveillance capabilities without the need for a separate video management system (VMS).

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.

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.

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.

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.

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.

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.
