Ask three security companies what a commercial system costs and you'll get a shrug, a lowball teaser rate, and a "well, it depends." The shrug is useless, the teaser rate always grows, and "it depends" is true but lazy, because nobody finishes the sentence. Here's the finished sentence: it depends on doors, cameras, detection points, and monitoring, and each of those has a logic you can actually follow.
The four numbers that build your quote
Every commercial security system is priced from the same four counts, whatever the salesperson calls the package.
Controlled doors. Each door that needs access control carries hardware: a reader, an electric lock, an exit device, and a position switch, plus its share of a controller. Per-door cost drops as door count rises because controllers are shared. Whether a door needs a basic card reader or a biometric unit moves the number more than any other single choice.
Camera positions. Camera count matters less than cable distance and mounting difficulty. A camera thirty feet from the network closet on an interior wall costs meaningfully less installed than the same camera at the far corner of a parking structure. Our camera installation page breaks down the cost drivers in detail.
Detection points. Door contacts, motion sensors, and glass-break detectors for intrusion detection are individually cheap; the design work is in zoning them so the system arms cleanly around your actual schedule.
Monitoring. The monthly fee for central station monitoring is the smallest line item and the one that makes the rest worth owning, hardware without response is just documentation of what went wrong.
Why single-location and multi-site pricing behave differently
A single storefront pays retail for everything, one trip, one setup, no shared infrastructure. That's why a business security system for one location is quoted as a project. Multi-site operators amortize: shared administration, bulk credentials, and staged rollouts pull the per-location number down even as the total grows. If you're quoting one building today but expect three by next year, say so up front, controller and platform choices made now decide whether site two is an add-on or a do-over.
Where budgets actually go wrong
The expensive mistakes we see aren't overspending, they're mis-spending. A building buys twelve cameras and zero door control, then rekeys the whole property twice in a year after staff turnover. Another puts a premium reader on every closet but leaves the loading dock on a mechanical key. A walkthrough that starts with "what actually goes wrong at this property" allocates the same budget better than any package sheet, which is why we quote after a site visit, not from a phone script.
The number nobody includes: what's already on your walls
If a previous vendor's equipment is installed, some of it probably still works. Panels, readers, cameras, and cabling that pass an audit get reused, and the quote shrinks accordingly. Our equipment takeover process exists precisely because ripping out functional hardware to sell new hardware is the industry habit we're happiest to break.
Getting a real number
A legitimate quote names every device, every door, and the monthly monitoring cost, and it doesn't move after the walkthrough. Anything vaguer is a teaser. Walk the property with us and the number you get is the number, across North Carolina, South Carolina, and Georgia through our local offices.
Three questions that shrink the quote before it's written
Before anyone walks your property, you can move the number yourself. First: which doors actually need control? Owners default to "all of them," but ranking doors by what's behind them usually trims a third off the access budget without losing anything that matters. Second: what footage would you actually pull? If the honest answer is entrances, cash areas, and the lot, you've just defined the camera plan. Third: what's already installed? Photograph every panel, reader, and camera on the property, including the ones that don't work, and send them ahead of the walkthrough. Equipment that passes an audit stays, and every reused device is a line deleted from the quote.
The recurring costs, stated plainly
Hardware is the number people negotiate; the recurring costs are the ones they forget to ask about. Monitoring is monthly and modest. Cloud-managed access control carries a subscription. Fire systems carry required annual testing that isn't optional and shouldn't be treated as a surprise. A complete quote lists all three next to the hardware, and a vendor who won't put the recurring numbers in writing beside the install price is planning to introduce you to them later.
