Manufacturing facility — 32 cameras, 90-day retention

Problem. A manufacturing facility with 32 cameras at 4MP H.265+ needs 90-day continuous retention for safety-incident review and process audit.

Answer. 32 × 4MP × H.265+ × 25 fps × 90 days of continuous recording lands around 124 TB of recorded data, which the calculator on this page provisions as about 162 TB once this preset's 30% headroom is applied — a multi-bay JBOD / SAN or VMS distributed-storage architecture, not a single desktop NAS.

02 / In depth

How this preset reads — the engineering view.

Industrial CCTV retention is process-audit driven before it is security driven. 90 days covers a typical batch / quality investigation window and the longest typical injury-claim filing window across most Indian state jurisdictions.

This preset assumes 32 cameras at 4MP H.265+, 25 fps and continuous recording (not motion-triggered — industrial processes need continuous frames for proper audit). The calculator returns the storage envelope; the real BOQ accounts for RAID 6 (recommended for arrays > 24 TB to handle dual-disk failure during rebuild).

Network: 32 cameras at this profile push roughly 128 Mbps aggregate to the NVR — the switch and the storage NIC need to comfortably absorb that with overhead. Plan for a dedicated CCTV VLAN.

Engineering notes: in factories with welding / strong EMI, IP-rated cameras and shielded patch cables are mandatory, neither of which the calculator surfaces. AMC is also non-negotiable at this storage scale — drive replacement is a when-not-if.

What this preset deliberately does not solve

  • Continuous recording (not motion-triggered) is the industrial norm — 2× the motion-only storage.
  • RAID 6 is recommended above 24 TB array size to survive dual-disk failure during rebuild.
  • AMC + drive replacement budget is a separate, mandatory TCO line.

How this preset differs from its siblings

The retail sibling preset uses motion-triggered recording and a 30-day retention window — both acceptable for loss-prevention where the evidence requirement is incident-level. This preset's distinguishing constraint is continuous recording (industrial process audit needs every frame, not just movement events) and a 90-day retention window that aligns with batch/quality investigation cycles and Indian state injury-claim filing windows. The result is a storage envelope an order of magnitude larger — and a network and RAID architecture conversation that the retail preset doesn't need.

02 / What that means, drawn

Cameras to rack · H.265+ · 90-day retention. Cameras: 32 cameras (4MP · 25 fps) — your figure. Per-camera stream: 4 Mbps, reached by profile default (Under review) — published figure. Recorded to disk: 128.0 Mbps, reached by × 32 × 100% duty (24/7 continuous) — computed here. Storage: 162 TB, reached by × 90 days + 30% (past 100 TB — plan a shelf) — past a stated limit. 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.
