The DHI-NVR616-64/128-4KS2 is a high-capacity Ultra Series NVR built for large-scale IP surveillance deployments requiring powerful AI capabilities, RAID redundancy, and seamless 4K video performance. Designed for mission-critical environments, it supports up to 128 channels and 16 HDDs, while enabling advanced AI-by-camera functions like facial recognition, ANPR, perimeter protection, and smart motion detection.
Key Features
-
Supports Up to 128 IP Channels – Flexible for large enterprise setups and multi-site installations.
-
AI-by-Camera Integration – Leverages IPC intelligence for face recognition, perimeter protection, SMD Plus, metadata, and more.
-
384 Mbps Recording Throughput – Ensures smooth storage, access, and forwarding for high-resolution streams.
-
RAID 0/1/5/6/10 Support – Provides secure, scalable storage with redundancy to prevent data loss.
-
Dual 4K HDMI Output – Two independent 4K HDMI outputs allow for crisp, multi-screen displays.
-
N+M Redundancy Cluster – Guarantees continuous recording by auto-failing over to backup if the main NVR goes down.
-
Remote IPC Management – Configure, upgrade, and manage cameras in bulk directly from the NVR interface.
-
Enterprise-Level Build Quality – Housed in a 3U chassis with 16 SATA III bays and SAS expandability for up to 160 TB.
Perfect For:
- Public safety control centers needing AI-based analytics

- Retail malls and hotels requiring large-scale IPC coverage
Install Tips
-
Use RAID 5 or 6 for the best balance between storage capacity and data protection.
-
Pair with AI-enabled Dahua IPCs to unlock full analytic features.
-
Ensure ample rack space (3U height) and proper ventilation due to high HDD count.
- Utilize dual HDMI for separate live view and playback screens.
-
Add ESS3116S-J storage cabinet via SAS port for archive expansion.
-
Enable N+M redundancy across multiple NVRs for mission-critical systems.

Extra Info
AI-by-Camera Integration
This NVR doesn’t process AI on its own—it pulls AI data directly from compatible Dahua cameras. This means less hardware overhead while still getting face detection, vehicle metadata, people counting, and more. For the best results, pair with Dahua WizMind IPCs.
N+M Redundancy
In N+M cluster setups, one or more standby NVRs are automatically activated if the main units fail, ensuring uninterrupted recording. Once the failed NVR recovers, the system syncs the missing footage from the standby unit.
RAID Storage for Security and Speed
RAID 0 offers max speed but no redundancy; RAID 5/6 is ideal for balancing fault tolerance and capacity. Supports up to 160 TB with internal drives, with further expansion via SAS.
Dual HDMI with Heterogeneous Output
Both HDMI ports support 4K, but each can display different content simultaneously—ideal for control rooms monitoring both live and playback feeds at once.
Smart Decoding & Playback
Self-adaptive decoding means less lag during playback. Multiple search options (by face, vehicle, event, metadata) make it easy to find key footage fast.
Q&A
Q: Does this NVR have built-in AI like face recognition?
A: No, it relies on AI functions performed by connected Dahua cameras.
Q: Can this support simultaneous RAID and recording to external storage?
A: Yes, it supports RAID for internal drives and SAS expansion for additional storage needs.
Q: How many cameras can I view live at once?
A: You can display up to 64 cameras on the first screen and up to 16 on the second screen.
Q: Does it work with third-party cameras?
A: Yes, it supports ONVIF and is compatible with brands like Axis, Sony, and Panasonic.
Q: Can I search recordings by face or vehicle?
A: Yes, if connected to Dahua cameras with face detection or vehicle metadata features.
Q: Can I control PTZ functions from the NVR?
A: Yes, via RS-485 or over IP if your PTZ camera supports it.
Q: How do I access the NVR remotely?
A: Use the Dahua DMSS app for mobile or access via browser using the IP address.
Q: What’s the benefit of dual HDMI output?
A: You can display live feeds on one screen and playback or event views on another—perfect for 24/7 control rooms.
