Dahua DHI-NVR4216-4KS2/L 16-Channel 4K Network Video Recorder for SMB Surveillance

Network video recorders are the central component of IP surveillance systems, and the Dahua DHI-NVR2116HS-4KS2 addresses this role as a compact 16-channel NVR for large residential installations and small commercial deployments. AI-enabled NVR solutions are deployed in office, retail, warehouse, and residential building surveillance systems where intelligent event detection and remote access are operational requirements.

The DHI-NVR2116HS-4KS2 supports simultaneous recording across 16 IP channels with decoding capacity of up to 4× 1080p@30fps streams and adaptive decoding for efficient hardware resource allocation. Video compression covers H.265 / Smart H.265+ / H.264 / Smart H.264+ / MJPEG with automatic codec switching, significantly reducing storage requirements compared to standard H.264 recording. Video outputs include 1× HDMI at up to 4K maximum resolution and 1× VGA at up to 1080p in simultaneous mode, with non-simultaneous output also supported across both interfaces. Built-in AI functions processed by the NVR include face detection and recognition on 1 channel, perimeter detection on 2 channels, or SMD (Smart Motion Detection) on 4 channels, with support for up to 10 face databases and 5,000 stored face images.

Camera compatibility is provided via ONVIF and RTSP protocols, ensuring interoperability with multi-vendor IP cameras in mixed or partial-upgrade installations. The Dahua UI 4.0 interface simplifies local configuration and device management. Remote monitoring is available through the Dahua mobile application, supporting live view and recorded video playback on iOS and Android devices. Dahua Security Baseline 2.1 defines the device's minimum cybersecurity protection standard against unauthorized access.

The Dahua DHI-NVR2116HS-4KS2 targets security system installers, integrators, and end users in the premium residential and small commercial segments deploying IP surveillance with AI analytics capabilities without a dedicated video analytics server. It is suited for projects where ONVIF compatibility with multi-vendor cameras, integrated intelligent detection functions, and unified remote management through a single application are primary selection criteria.
