PoE budget calculator for camera power planning.
Estimate camera draw, recommended headroom, and whether your switch or PoE recorder is likely to stay comfortable under load.
PoE Inputs
Use the published maximum PoE draw, not the average.
Optional if you want to compare against a switch or NVR.
PoE Result
Total Draw
64.0W
Recommended Budget
76.8W
Headroom Check
53.3% of available PoE used
Practical planning target: stay near or below 80% of the published PoE budget.
Use max published draw for each camera model, not average draw. If the resulting load is already close to the hardware budget, the safer answer is usually a larger switch.
After the rough calculation, move into the planner to evaluate real products and recorder compatibility together.
