Network Video Recorder DAHUA NVR4104HS-EI 4-channel 1080p, 1×SATA, 16 TB max, HDMI, VGA, 2×USB

DAHUA NVR4104HS-EI is a 4-channel network video recorder that supports up to 1080p resolution recording. Built on an industrial-grade processor and running Embedded Linux, the recorder manages IP cameras, stores footage on a local SATA drive (up to 16 TB) and provides multi-channel playback, remote viewing via web or mobile apps (iOS/Android) and configurable alarm linkage for centralized surveillance in homes, offices and small retail environments.

Advantages

The NVR4104HS-EI offers AI-assisted features including face detection and recognition, perimeter protection, SMD Plus and smart playback. It supports Smart H.265+/H.265 and H.264 compression to reduce storage and bandwidth needs, provides HDMI and VGA outputs up to 4K for local monitoring, and accepts third-party ONVIF-compatible cameras. The recorder supports up to four decoded playback channels, multiple recording modes (general, motion, intelligent, alarm) and backup via USB or network.

How to use

Install a compatible hard drive into the SATA bay (up to 16 TB), connect IP cameras to the network and use the web interface or local GUI to add cameras, configure recording modes and set schedules. Use the recorder’s AI settings to enable face detection, face recognition or SMD Plus per camera or per recorder channel. Configure alarm linkage to trigger recording, snapshots, external alarm outputs or notifications. Playback recordings via multi-channel playback, smart playback or event/tag search, and export footage using a USB device or over the network.

Usage recommendations

For reliable AI performance and smooth multi-channel decoding, use cameras and network settings that match the NVR’s supported bandwidth and resolution limits, enable Smart H.265+ where available to reduce storage, and store critical footage on a high-quality surveillance-grade HDD. Ensure firmware is kept up to date and follow Dahua’s compatibility list for third-party cameras.
