Industrial & Critical-Infrastructure Surveillance Planning Checklist

A one-page planning tool for a reliability-first industrial or critical-infrastructure surveillance build: the reliability layers (record-at-edge, ring network, N+1 recording servers, RAID 6 + hot spare, UPS/generator) with the availability target; the harsh-environment camera ratings to specify (IP66/67/69K dust/water, IK10 impact, NEMA 4X corrosion, temperature range) and the explosion-protection gate (ATEX/IECEx Zone vs Class/Division; explosion-proof vs intrinsically safe); the OT-segmentati
