Description
The Dahua NVR2108-4KS3 is a versatile 8-channel network video recorder designed to provide efficient and reliable video surveillance management for small to medium-sized applications, including residential, commercial, and industrial environments. It’s part of Dahua’s Lite series, offering advanced features and robust performance for a range of security setups.
Powered by an industrial-grade embedded processor, the Dahua NVR2108-4KS3 ensures stable and efficient operation while supporting Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG decoding formats, significantly reducing storage and bandwidth requirements without compromising video quality.
With a maximum decoding capability of 6 × 1080p at 30 fps and a bandwidth capacity of 80 Mbps for incoming and recording data, this NVR seamlessly handles high-resolution streams from IP cameras, supporting resolutions up to 12 MP.
It supports 4K resolution for scenes that require highly detailed images, and can serve as the edge, central, or backup storage with an intuitive shortcut menu for remote management and control, giving administrators flexibility in how the device fits into their broader surveillance architecture.
AI Capabilities on the Dahua NVR2108-4KS3 include AI by Recorder with 4-channel Smart Motion Detection (SMD) Plus, and AI by Camera with perimeter protection and SMD Plus, which distinguishes people and vehicles from irrelevant motion to reduce false alarms and enhance intelligent monitoring.
Storage is handled through a single SATA interface supporting HDDs of up to 20 TB, allowing for extensive video retention on a single drive, while a 10/100 Mbps Ethernet port ensures stable and secure network connectivity for continuous surveillance.
Video output is straightforward, with simultaneous HDMI (4K) and VGA (1080P) outputs available for local display, giving installers flexibility depending on the monitors already in place at a given site.
This NVR is designed with convenience in mind, featuring one-click arming and disarming for straightforward system control, letting administrators quickly enable or disable the video surveillance system without complicated settings.
Remote Surveillance capabilities allow P2P video playback on mobile devices via Dahua’s mobile apps, giving administrators the flexibility to monitor live or recorded footage from anywhere at any time.
Energy efficiency is well handled, as the Dahua NVR2108-4KS3 consumes less than 10W (without HDD) and operates on a 12 VDC, 1.5A power supply, performing reliably across a wide temperature range of –10°C to +55°C.
With its compact 1U design, flexible codec support, and straightforward remote access options, the Dahua NVR2108-4KS3 offers a cost-effective, reliable entry point into IP video surveillance for smaller camera deployments.
