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 in the 145–150 TB range once RAID-6 headroom is included — a multi-bay JBOD / SAN or VMS distributed-storage architecture, not a single desktop NAS.

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.
