Your numbers
Fields start empty; the worked example uses illustrative numbers, not a measured result.
Cameras, recorder and switch together, from their labels or the quotation.
Usually just the processing unit. This is the figure that belongs in a project case.

Enter your own figures, or load the worked example, to see the result.
No PGAK device wattage is assumed here. Ask for the figure for the processing unit you are quoted and enter it above.
How it is calculated
kWh = watts × hours ÷ 1000. Cost = kWh × tariff.
Worked example
A 60 W processing unit running 24 hours a day for 30 days at ₹8 per kWh, beside a 400 W whole system.
43.2 kWh added, costing ₹346 — against 288 kWh and ₹2,304 for the whole system.

What this does not tell you
Uses the wattages on your own equipment labels or quote. PoE losses are counted once, at the switch, never twice.
Published because buyers need the number. It is not a claim that PGAK sells a product for it.
Want this checked against your own site?
A PGAK business-case assessment goes through your cameras, your quotation and the numbers you entered here, and says plainly where the case is weak. Ask what your site would draw.
The result above is yours to keep either way — print it, save it, no contact details required.
