Hanwha XNV-9083R (4K AI IR Vandal Dome) storage & retention

Problem. A fleet of Hanwha XNV-9083R 8MP vandal dome cameras recorded continuously raises a real storage-sizing question: how much usable capacity does 30 days of 24/7 recording actually need, and what class of NVR head-end that capacity implies.

Answer. 16 Hanwha XNV-9083R cameras at 8MP H.265, continuous recording, over a 30-day retention window works out to roughly 41 TB of storage — about 86 GB per camera per day. At 16 cameras this sits in the Entry NVR architecture class. That figure is the recorded data volume; the calculator on this page reports about 51.4 TB, because this preset carries 24% headroom on top.

How this preset reads — the engineering view.

The XNV-9083R's 8MP sensor at a typical 8 Mbps H.265 bitrate and 30 fps is the storage driver here — it works out to roughly 86 GB per camera per day. H.265 is the reason that figure is manageable at all: at the same 8MP resolution, plain H.264 would push meaningfully more data per day for the same visual detail, since H.265's smart-codec compression does more work per bit.

Scaling is linear once the per-camera figure is set: 16 cameras × 30 days at ~86 GB/camera/day lands at roughly 41 TB. Add more cameras or extend retention and the number scales the same way — doubling either roughly doubles the storage. At 16 cameras and this bitrate profile, the resulting capacity sits comfortably within an Entry NVR head-end class rather than a multi-bay enterprise array.

Use the calculator by dragging camera count and retention days to see the storage total recompute live, and by switching the recording schedule — continuous 24/7 is the default here, but a motion-only schedule applies a duty factor that cuts the effective recorded hours per day, reducing storage well below the continuous figure for the same camera count.

The calculator does not decide real scene-activity bitrate variance (a busy entrance pushes more than a quiet corridor at the same nominal bitrate), RAID or redundancy overhead, failover or archive-tier storage, network write-throughput limits at the NVR, or the exact drive make-up and count for the final BOQ — those remain separate engineering decisions.

What this preset deliberately does not solve

  • The 8 Mbps figure is a scene-average bitrate at typical detail levels — busier scenes with more motion push higher, quieter scenes lower.
  • This preset models continuous 24/7 recording; switching to a motion-triggered schedule reduces effective recorded hours and storage accordingly.
  • The output is raw storage capacity before RAID or redundancy overhead, which a real BOQ adds separately.

How this preset differs from its siblings

The XNV-9083R's 8MP sensor and 8 Mbps H.265 bitrate sit above typical 4MP presets, so its per-camera daily footprint (~86 GB) is proportionally higher than a 4MP H.265 camera at a similar frame rate — resolution and bitrate, not camera count alone, are what move the storage figure. This page exists separately because the calculator's output is bitrate-and-resolution specific to this camera model, and a visitor sizing a fleet of XNV-9083R units needs the number for this sensor, not an average across the catalog.

Cameras to rack · H.265 · 30-day retention. Cameras: 16 cameras (8MP · 30 fps) — your figure. Per-camera stream: 8 Mbps, reached by profile default (Secondary source) — published figure. Recorded to disk: 128.0 Mbps, reached by × 16 × 100% duty (24/7 continuous) — computed here. Storage: 51.4 TB, reached by × 30 days + 24% (3.2 TB per camera) — computed here. PoE load: no figure (the PoE tool sizes this) — not sized here. Switching: no figure (ports are sized elsewhere) — not sized here. Rack: no figure (rack units come from the kit) — not sized here.

128.0 Mbps live before the duty factor · linear in cameras, bitrate and days

This preset’s storage chain uses the same profile, duty factor and headroom as the calculator. Published profile figures retain their source status. Scene coverage, PoE, switching and rack design are not sized by this calculation.
