Dahua DHI-NVR2108HS-8P-4KS3 Compact 8 CH 4K PoE NVR with SMD Plus
100% Official Brand / Serial Number Verifiable / 3-Year Warranty
(HDD no included)
- Compact 8-Channel Recorder: A 260 mm-wide 1U chassis fits space-conscious surveillance installations in villas, stores and small offices.
- Eight Direct PoE Connections: Eight IEEE 802.3af/at ports carry power and video, with a shared 72 W PoE budget.
- 4-Channel SMD Plus: Recorder-side filtering distinguishes human and motor-vehicle motion from irrelevant environmental movement.
- Up to 12 MP Camera Access: Supports high-resolution IP cameras, 4K HDMI output and up to six 1080p streams at 30 fps.
- Single-Bay Local Storage: One SATA interface supports an HDD up to 20 TB for recording, playback and event review.
- Camera-Side Analytics: Compatible cameras can provide SMD and perimeter protection across all eight channels.
Details
Compact Hardware for Focused Eight-Camera Projects
The Dahua DHI-NVR2108HS-8P-4KS3 combines eight IP camera channels, integrated PoE and local storage in a compact 260 × 232.5 × 47.6 mm enclosure. It is designed for surveillance systems in villas, retail premises and small offices where equipment space matters. All eight channels have corresponding PoE ports, allowing compatible cameras to receive power and transmit video through their Ethernet connections without a separate PoE switch.
Choose Where Intelligent Filtering Is Applied
The recorder provides four-channel SMD Plus, applying secondary filtering to distinguish human and motor-vehicle movement from activity caused by rain, leaves or changing light. For projects requiring analytics on more channels, compatible intelligent cameras can supply SMD or perimeter protection across the eight-channel system. This makes camera selection important when planning where advanced event detection will operate.
Resolution, Display and Storage Planning
- High-resolution access: Connects IP cameras up to 12 MP and outputs video through HDMI at up to 3840 × 2160.
- Conditional decoding: Handles up to six 1080p streams at 30 fps with recorder AI disabled, or four with AI enabled.
- Single-drive storage: One SATA interface supports one HDD up to 20 TB; recording duration depends on the configured bitrate, resolution and schedule.
- Audio support: One RCA input and one RCA output accommodate compatible external audio equipment.
