NR9581-V3 32-CH 8-Bay Recording Server — Australian Stock & 3-Year Warranty
The VIVOTEK NR9581-V3 is an enterprise-grade 2U rackmount recording server built for large, mission-critical surveillance deployments. It records 32 channels out of the box and expands to 128 channels through VSS Pro, with eight hot-swappable 3.5" HDD bays and full RAID 0/1/5/6/10/50/60 for storage redundancy. Dual 2.5GbE networking, redundant power and video output up to 4096×2160 (4K) make it ideal for data-centre-class recording. Note it has no built-in PoE — cameras connect through a separate PoE switch.
