Extra Info
AI Features by Camera
This NVR is optimized to support AI analytics when used with compatible Dahua AI cameras. These include SMD Plus (human/vehicle classification), perimeter intrusion detection, face recognition, and license plate capture. It acts as a smart AI bridge — triggering alerts, allowing filtered searches, and offering advanced metadata tagging.
Fisheye Dewarping
Built-in dewarping allows users to digitally correct 360° fisheye views from compatible panoramic cameras, offering normal perspective views in playback or live. This enhances usability for wide coverage areas like warehouses or large public spaces.
RAID and Redundancy
With support for RAID 0/1/5/6/10, the unit offers flexible data protection schemes. RAID 5 is ideal for balancing usable space with redundancy in medium-sized deployments, while RAID 6 is recommended for critical systems.
Interoperability
Beyond Dahua cameras, this NVR supports ONVIF Profile T/S/G and major brands like Axis, Panasonic, and Sony, making it a fit for hybrid systems or camera upgrades.
Mobile App Access
The DMSS app allows users to check live views, playback events, and receive push notifications from anywhere. Perfect for property managers, installers, and end users.
Q&A
Q: Can I use this NVR with non-Dahua cameras?
A: Yes, it supports ONVIF and is compatible with popular brands like Axis, Pelco, Sony, and more.
Q: Does it have built-in analytics or rely on camera-side AI?
A: Most analytics such as face recognition, ANPR, and people counting rely on camera-side AI. The NVR interprets and stores this metadata.
Q: Is fisheye dewarping done in real-time?
A: Yes, one channel of fisheye dewarping is supported in both live and playback modes.
Q: Can I use all 8 HDD slots at once?
A: Yes, the system supports 8 SATA III drives with up to 10TB per slot, and hot-swapping is supported.
Q: How do I set up RAID?
A: RAID setup is available through the local GUI or web interface. You can configure RAID 0/1/5/6/10 depending on your needs.
Q: Does the unit have a built-in speaker or mic?
A: No internal mic/speaker, but supports RCA audio input and two-way audio output to external devices.
Q: Can I view the system remotely?
A: Yes, via the DMSS app for iOS and Android or using a secure web browser interface.
Q: What’s the benefit of dual HDMI/VGA outputs?
A: Allows separate display setups — e.g., a control room multi-view plus a single-camera focus for security guards.
