How the recommendation is gated
- Single-port power is checked first. A high-power PD cannot run on a lower IEEE port type even when the switch has enough total budget.
- Whole-switch PoE budget is checked second. Per-port labels do not mean every port can deliver that maximum at the same time.
- Use maximum PD input, not average draw. Boot, heater, IR, radio and PTZ movement can increase demand.
- This is an initial shortlist. Confirm cable length, temperature, redundancy, VLAN, security, optics distance and the exact SKU datasheet.
