DAHUA 4-Channel PoE NVR with 2TB HDD Installed. 4 Onboard PoE Ports, Max Decoding 2ch@ 4K, 8ch@ 1080P, Supports H.265+ / H.264+, 1x HDMI, 1x VGA Output.

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 serve 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 centres, 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 systems (VMS). It features an open architecture that supports multi-user access and is compatible with ONVIF Profile S, T & G protocol, enabling interoperability with IP cameras. 

Features:

• New 4.0 user interface, Security baseline 2.1
• H.264, H.265, Smart H.264+, and Smart H.265+. H.265 auto switch· Max. decoding capability: 8 × 1080p@30 fps. Supports adaptive  decoding
• Supports mainstream cameras of ONVIF and RTSP protocols
• P2P remote surveillance, video play on a mobile device
• VGA/HDMI simultaneous video output, the maximum resolution of HDMI is 4K
• AI by Camera: Face detection, perimeter protection, IVS, people counting, heat map, and SMD
• Supports remote configuration and management of IPC, such as setting parameters, getting information, and upgrading IPC of the same model in batches

Perimeter Protection by Camera
Automatically filtering out false alarms caused by animals, rustling leaves, bright lights, etc. Enables the system to act as 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 outputs the best face snapshot. 

SMD Plus by Camera
With an 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 alarms.

People Counting by Camera
With a 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 a management platform, it outputs yearly/monthly/weekly/daily reports to meet your requirements.

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

DMSS
Video is recorded on SD card in IP cameras when the network breaks down, and after the network is recovered, the video will be transferred to the device and then recorded in it.
