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
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 More information: Processor | Built-in processor | Yes | Ports & interfaces | Ethernet LAN (RJ-45) ports | 1 |  | Power over Ethernet (PoE) | Yes | | Ethernet LAN data rates | 10,100,1000 Mbit/s | | Power over Ethernet (PoE) ports quantity | 16 | | HDMI ports quantity | 1 | | VGA (D-Sub) output ports | 1 | | USB 2.0 ports quantity | 2 | | Audio RCA inputs | 1 | | Audio RCA outputs | 1 | Operational conditions | Operating temperature (T-T) | -10 - 55 °C | | Operating relative humidity (H-H) | 10 - 90 % | | Storage temperature (T-T) | 0 - 40 °C | | Storage relative humidity (H-H) | 30 - 85 % | Features | Rack mounting | Yes | | Rack capacity | 1U | | Product colour | Black | Power | Power consumption (typical) | 10 W | | AC input voltage | 100 - 240 V | | AC input frequency | 47 - 63 Hz | | Power over Ethernet (PoE) power per port | 25.5 W | | Total Power over Ethernet (PoE) budget | 117 W | Performance | Video input channels | 16 channels | | Maximum resolution | 3840 x 2160 pixels | | Alarm input channels | 4 | | Alarm output channels | 2 | | Video motion detection | Yes | | Multi-screen | Yes | | Video formats supported | H.264, H.265 | | Operating system installed | Embedded LINUX | | Maximum frame rate | 30 fps | Weight & dimensions | Width | 375 mm | | Depth | 320 mm | | Height | 48.2 mm | | Weight | 2630 g | | Package weight | 3910 g | Storage | Maximum storage capacity | 8 TB | | HDD interface | Serial ATA | | Number of HDDs supported | 2 |
