-
Fisheye Dewarping – Built-in one-channel dewarping transforms distorted views into usable footage during live or playback.
-
Smart Search Tools – Quickly locate footage based on vehicle color, clothing, license plate, and other attributes.
-
Dual HDD Bays – Supports up to 20TB of storage for long-term retention and high-resolution recording.
-
High Incoming Bandwidth (320 Mbps) – Ensures smooth multi-channel recording at up to 12MP resolution.
-
DMSS Mobile App Compatible – Offers remote access, push notifications, and playback from smartphones and tablets.
-
ONVIF Interoperability – Works with major third-party cameras like Axis, Hikvision, Panasonic, and others.
Perfect For:
- Office and business parks
- Schools and training campuses
- Car dealerships and vehicle yards
- Retail chains with high foot traffic
- Gated residential complexes
- Health clinics and public service buildings
Install Tips
-
Use with Dahua AI Cameras to unlock face recognition, metadata, people counting, and more—NVR doesn’t process AI internally.
-
Utilize All 24 PoE Ports without a switch—ideal for installations with high channel density.
-
Enable Smart H.265+ for longer retention on the same HDD capacity.
-
Mount in Rack with Airflow—unit is compact 1U but ensure front/rear clearance for passive cooling.
-
Set Up Metadata Search Indexing in advance to speed up future investigations.
-
Use Fisheye Cameras on Entry Points and apply NVR dewarping to get panoramic clarity.

Extra Info
AI by Camera Integration
The NVR works in tandem with Dahua's AI cameras. AI features like SMD Plus, face recognition, ANPR, and people counting are processed at the camera level. The NVR indexes and organizes this data for smart search and event playback.
Metadata Search Capabilities
By leveraging metadata from compatible AI cameras, this NVR enables advanced searches. For example, find footage of a person in a red jacket or a blue vehicle with a specific plate pattern, speeding up investigations dramatically.
Fisheye Dewarping
Ideal for panoramic coverage at entrances or lobbies. This model supports one-channel real-time dewarping, transforming distorted fisheye views into usable scenes.
Efficient Compression with Smart H.265+
Reduce bandwidth and storage requirements without compromising quality. Ideal for long-term recording and sites with bandwidth limitations.
Remote Access with DMSS App
Get instant push alerts, live view, and playback control remotely. The DMSS mobile app keeps admins in the loop without needing a full desktop workstation.
Interoperability with Third-Party Cameras
Thanks to ONVIF 2.4 compliance and Dahua’s open architecture, this NVR supports major brands like Axis, Sony, and Hikvision, though advanced AI features will only be available when paired with Dahua AI-enabled cameras.
Q&A
Q: Can I use this NVR with non-Dahua IP cameras?
A: Yes, it supports third-party brands via ONVIF, but advanced AI features only work with Dahua AI cameras.
Q: Does it support full-colour or night vision cameras?
A: Yes, but night vision capability depends on the cameras you connect—this NVR records whatever stream the camera sends.
Q: Can I disable the fisheye dewarping if I don’t use that type of camera?
A: Absolutely. Dewarping is only applied to supported fisheye streams and is not required for standard cameras.
Q: How long will recordings last with two 10TB drives?
A: This depends on camera count, resolution, frame rate, and compression. With Smart H.265+, you can expect 30+ days for standard 24/7 use with mixed resolution cameras.
Q: Can I receive push alerts to my phone?
A: Yes, the DMSS app supports motion alerts, AI event notifications, and snapshot delivery to mobile devices.
Q: Will this trigger alarms automatically?
A: Yes, when paired with AI cameras, the NVR can trigger alarms based on human/vehicle detection, facial match, ANPR, and more.
Q: What’s the difference between this and the 16P model?
A: The 5224 has 24 PoE ports vs 16, making it more suitable for higher camera density installs without extra switches.
