Change the system size and response model to compare likely cost structures before requesting provider quotes. ILLUSTRATIVE RESULT
The planning range applies −20% to +40% around the assumptions to show how product tier, promotions, taxes and labour can change the result. It does not include broadband, electrical work, structural cabling, repairs, permits or insurance changes. Every calculation includes one control hub/base. Country selection changes the currency and local planning values. The model adds the selected equipment, an installation allowance and 12 or 36 months of the chosen service.

Planning estimate—not a quote: defaults are transparent editorial assumptions, not claimed market averages. Actual prices, taxes, subscriptions, compatibility and installation requirements vary by country, property and provider.
Equipment + installation
Ongoing monthly
Three-year planning total
Compare like with like: ask whether a quote includes equipment ownership, installation, taxes, cloud storage, cellular backup, maintenance, contract increases, cancellation charges and replacement batteries. Never assume monitoring guarantees crime prevention or police attendance.
