- Office buildings requiring face recognition and door access logging
- Airport/transport hubs for people flow and license plate tracking
- Warehouse/perimeter security with motion detection and intrusion alerts
-
Educational campuses for crowd density and security analysis
Install Tips
- Rack Mounting – Fits standard 1.5U bays; ensure adequate ventilation to dissipate heat from HDDs.
- Use PoE Smartly – Prioritize higher-powered cameras like PTZ on ports 1–8; ports support ePoE.
- Balance Data Load – Activate AI analytics only on critical channels to stay within 200 Mbps AI mode bandwidth.
- Configure RAID – Use RAID‑5 with four drives for data redundancy and efficient recovery.
- Optimize Display Configuration – Use HDMI1 for combined multi-channel view, HDMI2 for single high-resolution streams.
-
Utilize Smart Playback – Tagging by face/perimeter makes searching footage after events much faster.

Extra Info
WizSense AI Engine
Combines an independent AI chip with deep learning to filter false positives (e.g., leaves or shadows) and focus on people, vehicles, and faces.
Face Detection & Recognition
Up to 16 channels can detect faces and match them against a database of 20k images—ideal for access control or attendance logging.
Perimeter Protection & SMD Plus
Detects intrusion or line crossing on 4 recorder channels with 10 IVS rules each; SMD Plus further refines alarms by filtering irrelevant motion.
Metadata & ANPR
Camera-side analytics include stereo behavior analysis, heat mapping, vehicle density metrics, and license plate reading (up to 8 channels simultaneously).
Smart Playback & Tag Search
Enables event-centric review by time, event type (face, motion), tags, or labeled faces for efficient investigation.
Hybrid Output Support
Dual HDMI/VGA outputs allow for different simultaneous feeds—such as overview on one screen and detailed zoomed view on another.
Open Integration
With ONVIF and SDK support plus compatibility with other vendors, it integrates well into existing multi-brand infrastructure or VMS platforms.
Q&A
Can it power cameras via PoE?
Yes—16 PoE ports (1–8 support extended PoE) with a total 130 W power budget and up to 25.5 W per port.
What happens if AI analytics exceed bandwidth?
AI mode supports up to 200 Mbps; exceeding that will prompt the NVR to disable AI features on lower-priority channels.
How many drives can I install?
It supports 4 SATA disks up to 16 TB each, plus an eSATA port for external storage expansion.
What’s the difference between recorder-side and camera-side AI?
Recorder-side AI handles up to 2 face recognition streams, 4 perimeter channels, 8 SMD channels. Camera-side AI offloads analytics to smart cameras using metadata and off-NVR processing.
Does it support remote viewing apps?
Yes, it works with Dahua’s mobile apps (iOS/Android), web GUI, and integrates with third-party VMS via ONVIF.
Can I back up footage easily?
Yes—backup via USB drive or network, with smart tag-based clip selection.
Does it support RAID?
Yes—disk group configurations with RAID help ensure data integrity.
Is face database large enough for many employees?
Absolutely—supports up to 20k face images across multiple databases with metadata.
