ACTi - ZNR-425 - 32-Channel 4-Bay 1U Rackmount Standalone NVR
Product Overview
This 32-channel 4-bay 1U rackmount standalone NVR is designed for centralized video surveillance recording and management. It runs on Embedded Linux with an ARM-based embedded SoC and includes built-in Core Analytics, forensic search, smart search, object visual tracking, and multi-browser access.
Key Configuration
32-channel rackmount standalone NVR with 32 free licenses; 4 storage bays for local video recording; 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 provide local recording capacity for surveillance footage
• Built-in Core Analytics supports intelligent video analysis
• Forensic Search, Smart Search, and Object Visual Tracking support efficient investigation workflows
• Multi-browser support enables flexible browser-based system access
Technical Context
The NVR combines embedded standalone recording with analytics-assisted search functions for security monitoring and review. Forensic Search, Smart Search, and Object Visual Tracking help operators locate relevant events more efficiently across recorded video.
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.
