Key Points (Text Version)

  • VLAN isolation: Physically isolate the core plant area and perimeter; use logical VLAN isolation for office floors and auxiliary zones — a better balance of security and cost.
  • PoE power budget: Per-port power × port count × 0.8 redundancy factor. For 24 cameras at 15W, theoretical demand is 360W, so choose a PoE switch with total power no lower than 450W.
  • Bandwidth planning: Keep the access-layer convergence ratio within 3:1; size total bandwidth as "camera count × per-stream bitrate × peak factor 1.2–1.5"; expand when utilization exceeds 70%.
  • Five-step rollout: Assess the current state → tier the design → leave power headroom → draw the IP plan → establish an operations baseline.
  • Southeast Asia localization risk: Monsoon-season power fluctuation is common — equip the server room with an online UPS to avoid repeated reboots and recording loss.
