Network Video Recorder DAHUA NVR4108HS-8P 8-channel with 8 PoE ports

DAHUA NVR4108HS-8P is an 8-channel network video recorder with eight built‑in PoE ports designed for small to medium surveillance systems. The recorder runs Embedded Linux on an industrial‑grade processor and provides local GUI and web interfaces for system configuration and live view. It supports AI functions across recorder and camera, including face detection and recognition, perimeter protection, SMD Plus, ANPR, people counting, stereo analysis and heat map. The device accepts multiple video resolutions up to 16 MP, supports Smart H.265+/H.265/H.264 compression, and offers HDMI and VGA video outputs with multi‑screen display options.

Advantages

The recorder integrates PoE ports for direct camera connection and power delivery, simplifying installation for offices, shops and homes. Its AI capabilities combine recorder‑side and camera‑side analytics—face attributes extraction, database management and perimeter protection—while SMD Plus reduces false alarms from environmental effects. The unit supports multiple recording modes, multi‑channel playback, flexible backup via USB or network, and interoperability with third‑party ONVIF cameras.

Suitable for

• Small and medium business surveillance (retail stores, offices)
• Residential security and gated properties
• Entrances and access control with face recognition and ANPR
• Areas requiring people counting, heat maps or perimeter protection

How to use

Install the recorder on a rack or desktop and connect IP cameras directly to the eight PoE ports for simultaneous data and power delivery. Configure network settings and add cameras via the local GUI or web interface; the unit also supports auto register and Dahua device search. Create recording schedules and select record modes (general, motion, intelligent, alarm). Manage AI functions by assigning face databases, enabling perimeter rules or SMD Plus filtering, and adjust decoding settings based on required resolution and performance. Use HDMI or VGA outputs for local monitoring and the mobile apps (iOS/Android) or browser clients for remote access.

Usage recommendations

For optimal AI performance, enable AI features according to camera capabilities and balance resolution versus channel decoding: higher resolutions reduce the number of simultaneous high‑resolution channels when AI is active. Keep firmware updated, configure network bandwidth limits if AI is enabled, and use quality PoE cables and appropriate HDD rated for surveillance to ensure reliable recording.
