ACTi - KNR-420 - 32-Channel 4-Bay RAID 1U Rackmount Standalone NVR
Product Overview
This 32-channel 4-bay RAID 1U rackmount standalone NVR is designed for centralized surveillance recording and video management. It supports onboard hardware RAID, built-in Core Analytics, forensic search, smart search, object visual tracking, and multi-browser access for efficient security operations.
Key Configuration
32-channel rackmount standalone NVR with 32 free licenses; 4 storage bays with onboard hardware RAID 0, 1, 5, 6, and 10; 1U rackmount form factor; Embedded Linux with ARM-based embedded SoC; audio, HDMI x 1, and VGA x 1 interfaces.
Key Features
• Supports up to 32 video channels with 32 free licenses included
• Four storage bays support scalable recording capacity
• Onboard hardware RAID supports RAID 0, 1, 5, 6, and 10 configurations
• Built-in Core Analytics, Forensic Search, and Smart Search support efficient video review
• Object Visual Tracking and multi-browser support improve investigation and access workflows
Technical Context
The NVR combines embedded standalone recording with RAID-based storage options and analytics-assisted search tools. Forensic Search, Smart Search, and Object Visual Tracking help operators locate relevant activity more efficiently across recorded surveillance footage.
Installation Notes
The 1U rackmount design is intended for installation in standard equipment racks. HDMI and VGA outputs allow local monitor connection for setup, live viewing, or system operation.
