About this product
A 4-bay NAS that adds hot-swap surveillance storage to a VMS or a high-channel NVR that has run out of internal bays. Four 3.5" SATA trays take enterprise drives for months of retention, with RAID for data safety and a 1U footprint for the comms rack. Network-attached, so multiple recorders or a VMS can share the archive.
