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.
02 / In depth
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.

Hikvision DS-2CD2387G2-LU (ColorVu 8MP) storage & retention
A fleet of Hikvision DS-2CD2387G2-LU (ColorVu 8MP) cameras generates far more footage per day than a lower-resolution camera, so storage sizing has to start from this camera's actual bitrate rather than a generic rule of thumb. Get the drive capacity wrong at design stage and a 30-day retention promise quietly shrinks the moment continuous recording begins.

Hikvision DS-2CD2143G2-I (4MP Dome): storage & retention
A fleet built around the Hikvision DS-2CD2143G2-I (AcuSense 4MP Dome) puts a real number on what 30-day continuous retention costs in raw storage, and that number is easy to underestimate at 4MP. The right question is not just how large a single camera's footage is, but how the count of cameras, the retention window and the recording schedule compound into a head-end and drive plan.

Hikvision DS-2CD2T87G2-L (ColorVu 8MP) storage & retention
A fleet of Hikvision DS-2CD2T87G2-L (ColorVu 8MP Bullet) cameras recording continuously puts real weight on the storage decision — 8MP frames at a typical 16 Mbps bitrate accumulate fast, and under-sizing the NVR is the single most common CCTV retrofit mistake. The question a buyer actually needs answered is how many terabytes a 30-day continuous-recording policy demands, and what class of head-end that quantity of storage implies.

Hikvision DS-2DE4425IW-DE(T5) 4MP PTZ — storage & retention
A site standardising on the Hikvision DS-2DE4425IW-DE(T5) 4MP 25x PTZ needs to size an NVR and disk array before deciding how many cameras it can run and for how long, since a 25x PTZ's 4MP sensor at continuous frame rates writes meaningfully more data per day than a fixed 2MP dome.

Dahua IPC-HFW5849T1-ASE-LED (8MP TiOC) storage & retention
Sizing storage for a fleet of the Dahua IPC-HFW5849T1-ASE-LED (8MP TiOC) is not a guessing exercise once resolution, codec, and frame rate are fixed. The real decision is how many days of continuous 8MP footage a site needs to retain, and what head-end class of NVR that retention actually demands.

Dahua DH-IPC-EBW81242N (12MP Fisheye) storage & retention
A fleet of Dahua DH-IPC-EBW81242N (WizMind 12MP Fisheye) cameras generates far more data per hour than a typical 2MP or 4MP dome, so the real decision is not whether to record but how much NVR and drive capacity a 30-day retention policy actually demands. Getting the storage math wrong at design stage means either an under-built NVR that overwrites footage early, or an over-built one that wastes budget on capacity nobody needed.

A site standardising on the Dahua DH-IPC-HFW2431S-S-S2 (Lite 4MP IR Bullet) needs to know what a fleet of these cameras actually costs in storage terms before the NVR and drive array are specified. The real decision is not the camera — it is what 30 days of continuous recording across the fleet does to the head-end architecture.

Axis P3268-LVE — storage & retention planning
An 8MP camera recording continuously produces a meaningfully larger daily file than the 2-4MP cameras most storage rules of thumb are written for, so a fleet-level estimate has to start from this camera's own bitrate rather than a generic assumption. Getting the per-camera-per-day figure right before specifying an NVR avoids under-sizing storage or over-buying a head-end class the fleet does not need.

Axis AXIS P3245-LV (2MP) — storage & retention
A fleet of Axis AXIS P3245-LV (2MP) dome cameras recording continuously for 30 days needs a head-end sized before the NVR is ordered, not after. Getting the per-camera daily footprint wrong at the planning stage means a disk array that either runs out of retention early or sits over-provisioned.

Axis Q6135-LE storage & retention (2MP, H.265)
A fleet of Axis Q6135-LE cameras recording continuously raises a straightforward but easy-to-underestimate question: how much usable storage does 30-day retention actually demand, and what class of head-end can hold it. Get the sizing wrong and a project either overspends on drive bays it does not need or runs out of retention days before the footage is reviewed.

Hanwha Wisenet XNB-9002 (4K) storage & retention
An 8MP camera at H.265 shifts the storage conversation from 'how many terabytes' to 'how many camera-days'. Once a fleet of Hanwha Wisenet XNB-9002 (4K) units is set to continuous recording at a 30-day hold, the daily footprint per camera becomes the number that decides the whole head-end.

Bosch FLEXIDOME IP starlight 8000i (4K) storage & retention
An 8MP camera recording continuously generates far more footage than a 2MP or 4MP unit, so a fleet-wide storage and NVR plan needs to be sized around the actual bitrate this model produces, not a generic rule of thumb. Getting the 30-day retention figure right up front avoids a mid-project scramble to add drives or swap the head-end once real footage volumes show up.

Uniview IPC2328SB-DZK-I0 (8MP) storage & retention
A fleet of Uniview IPC2328SB-DZK-I0 (8MP LightHunter) cameras generates far more footage per day than a 2MP or 4MP fleet, so the real decision is how much drive capacity and what NVR class a 30-day retention policy actually needs. Getting the storage math wrong at design stage means a mid-project drive upgrade or a head-end that cannot keep pace with continuous recording.

Vivotek FD9389-HM (5MP Dome) storage & retention
A fleet of Vivotek FD9389-HM 5MP dome cameras recording continuously will fill a head-end far faster than the same count in 2MP, so the storage math has to be worked out before the NVR and disks are chosen. The real decision is not the camera itself but how many days of footage the site needs to keep at that resolution, since retention is what drives the drive count.

Avigilon H6A Dome (8MP) storage & retention
A fleet of Avigilon H6A Dome (8MP) cameras generates far more footage per day than a standard-definition camera, so a 30-day retention target can quietly outgrow a modest NVR if storage is sized by guesswork. Getting the per-camera daily figure right before ordering hardware avoids either an under-sized head-end or an over-bought one.

Milesight AI Mini Dome 5MP: storage & retention
A fleet of Milesight AI Mini Dome 5MP cameras generates meaningfully more footage per day than a 2MP or 4MP line, so sizing the NVR and drive pool around guesswork risks either wasted spend or a retention window that runs out early. The real decision is how many days of continuous 5MP footage a given camera count must hold, and what head-end class that implies.
