Plan before you buy
Twelve tools, built on one published set of formulas. They run entirely in your browser, they show a negative answer as readily as a positive one, and none of them assumes a PGAK price — you type in the quotation you were given.
Will AI on my existing cameras pay for itself, and by when?
Enter the quote you were given and only the benefits you can defend. Returns monthly net cash, cumulative position, payback month, ROI% and benefit/cost ratio — including when the answer is no.
Is adding AI to my cameras cheaper than replacing the system?
Compares both options over the same horizon: upfront + operating + mid-life replacements − residual value. Retrofit does not automatically win, and an unknown on either side blocks the verdict.
How much disk do I need to keep N days of footage?
Camera count × recorded bitrate × recording hours, in decimal TB, with the free-space reserve and any RAID overhead kept as separate steps.
What link do I need, and what would cloud transfer cost?
Simultaneous streams × bitrate sizes the link, with headroom shown separately. Transferred data is computed from real traffic, never inflated by the headroom factor.
What is a realistic recovery on documented stock loss?
Documented eligible loss at cost × an improvement you choose or observed in a pilot. No default 'typical' recovery percentage is supplied.
How many hours does searching footage cost us each month?
Incidents × (minutes before − minutes after) ÷ 60, reported as hours and capacity value, separate from any cash saving.
What does reconciling attendance actually cost us?
Actual administration and reconciliation hours before versus after, with any verified payment correction kept separate.
What do nuisance alerts cost us every month?
Difference in false alerts × handling minutes × days ÷ 60, as hours and capacity value.
Which site visits could remote checks replace?
Avoidable visits × actual travel and accommodation expense. Travel time is reported separately as capacity.
How much gate time would plate recognition save?
Vehicles × processing-time difference × days, with theoretical capacity shown separately from real queue throughput.
What would a small conversion change be worth?
Visitors × conversion-rate change (in percentage points) × order value × contribution margin, minus extra costs.
What will this add to the power bill?
Watts × hours ÷ 1000 × tariff, with whole-system power and the incremental project power kept apart.
Every feature PGAK documents has a short calculator on its own page — 31 in all. Each uses your measurements, reports staff time apart from cash, and says what evidence the feature rests on. Where two features save the same staff time, count it once.
Bring the numbers you produced here. We check them against your cameras and your quotation, say which benefits we think you can defend and which we cannot, and set acceptance criteria for a pilot so the case can be measured rather than argued.
The calculators stay free and ungated whether or not you ask for this.
Share your phone number, city and camera count. We will clarify the intended use case and agree assessment scope and timing with you. Do not submit camera credentials or footage.
