- WiseStream technology for optimized bandwidth and storage efficiency
Recording & Playback Performance
The XRN-3220B4 maintains 520 Mbps recording bandwidth in all operating states—normal, RAID degraded, and RAID rebuild modes—ensuring uninterrupted capture during storage events. Dual-stream recording enables simultaneous storage of multiple quality levels, allowing bandwidth-efficient archival while preserving full-resolution primary streams. Playback bandwidth reaches 200 Mbps, supporting multi-channel review and forensic investigation. Flexible resolution modes span 32MP, 12MP, 8.3MP, 1080p, 720p, and D1 with frame-rate customization for each stream.
Storage & Reliability Architecture
With 16 SATA HDD bays rated for 10TB drives each, the system ships with 32TB and scales to 160TB maximum capacity. RAID 5 and RAID 6 protection delivers automatic fault tolerance, while hot-swap capability eliminates downtime during drive replacement. Automatic Recovery Backup (ARB) with N+1 failover ensures system continuity during hardware failures. iSCSI support enables extended or secondary storage for long-term retention and compliance workflows.
Network Integration & Bandwidth Optimization
Native PoE compatibility simplifies multi-camera deployments without dedicated power infrastructure. WiseStream codec optimization reduces bandwidth and storage footprint without compromising image quality, extending recording duration and reducing operational costs. Multiple display layouts—including 32-division clone mode and expandable grid views—support command center and remote monitoring workflows. Event recording modes (continuous, scheduled, pre/post event, and triggered) enable flexible capture strategies aligned with security policies.

The XRN-3220B4 targets high-capacity enterprise deployments where native 8K support and codec flexibility justify higher upfront investment. The 520 Mbps bandwidth guarantee across all RAID states is a notable strength for mission-critical facilities; RAID rebuild no longer throttles recording. WiseStream integration addresses operational cost concerns inherent to 32-channel systems by intelligently adapting compression without manual rule configuration.
RAID 6 and ARB redundancy suit environments where storage downtime triggers compliance penalties or security incidents. The Intel-based architecture ensures long-term software support and vendor stability for public-sector and large enterprise buyers. Best suited for airports, transportation hubs, large retail chains, and government facilities requiring proven reliability and scalable storage.
