Most security companies will not put a number on a page, which is exactly why you are reading this one. Here is the honest position: a commercial security system is priced by the building, not by the business, and anyone quoting you before they have walked the site is guessing. What we can do is show you the ranges, explain what moves them, and tell you which decisions actually change the number.
What Drives the Price
Five things account for most of the variation between two quotes for what sounds like the same job.
Number of doors and camera positions. The single biggest driver. Each controlled door needs a reader, a lock, a power supply and a cable run. Each camera position needs a mount, a cable run and a share of recording storage.
Cable routing. Running cable through an open ceiling in a new build is straightforward. Running it through a finished 1920s masonry building with no accessible ceiling is not, and that difference can be a large share of the labour on a small job.
Door hardware. If your existing frames, closers and strikes can carry an electric lock, you keep them. If they cannot, hardware replacement is added to the scope. This is the most common source of a quote coming in above expectation.
Camera resolution and coverage goals. There is a real difference between seeing that a person was there and being able to identify them. Identification-grade coverage needs more cameras at tighter fields of view, or better cameras at the same positions.
Monitoring and support. A monitored system carries an ongoing monthly cost. An unmonitored one does not, but nobody is watching it either.
Typical Ranges by System Type
These are the ranges we see on real jobs across New Jersey, New York and Pennsylvania. They are starting points for a conversation, not a quote.
Camera systems. A small business with 4 to 8 camera positions and a recorder typically lands in the low thousands installed. A mid-size site with 16 to 32 positions, higher-resolution cameras and longer retention runs into the mid five figures. Multi-building sites are priced per building.
Access control. Priced per door. A single controlled entrance is the smallest sensible job. A typical office suite controls 3 to 6 openings. Cost per door falls as the number of doors rises, because the controller and software are shared.
Intrusion alarms. The equipment is the cheaper part. Monitoring is the recurring cost and it is billed monthly per system, sometimes with a per-zone element on larger sites.
Intercom and video entry. A single entrance station with interior answering points sits at the lower end. Multi-tenant buildings with a directory and per-unit answering cost more, and the cabling in an existing building is usually the deciding factor.
Integrated systems. Combining cameras, access control and alarms on one platform costs more up front and less over time, because you are not paying three vendors to maintain three systems that do not talk to each other.
Cost by Building Size
Single small unit, one to two doors, under 2,000 sq ft. Usually a camera system plus one controlled door. The smallest realistic commercial scope.
Office suite or single retail store, 2,000 to 10,000 sq ft. 8 to 16 cameras, 3 to 6 controlled doors, a monitored alarm and often an intercom at the main entrance.
Multi-tenant building, warehouse or school, 10,000 sq ft and up. Phased by area or by building. Expect a design phase before any pricing is final, and expect the network infrastructure to be a line item in its own right.
Where People Overspend and Underspend
Overspending usually looks like camera count for its own sake, resolution far beyond what the coverage goal requires, and long retention periods nobody will ever review. Retention in particular is worth thinking about, because storage cost scales with it and most incidents surface within days, not months.
Underspending usually looks like skipping the network. A camera system is only as reliable as the switch, the cabling and the power behind it, and saving on those is how a system that worked at handover stops working eight months later. The other common false economy is leaving one door uncontrolled because it is awkward to cable. That is the door that gets used.
How to Compare Two Quotes Fairly
Ask every provider for the same four things and comparison gets much easier.
An itemised scope: what equipment, how many, where. A lump sum tells you nothing.
Ownership: do you own the equipment at the end, or are you leasing it?
Contract length and what happens when it ends.
What is excluded: door hardware, network switches, electrical work and permits are the usual omissions, and they are the usual source of a change order later.
Commercial Security System Cost FAQs
Can you give me a price over the phone?
We can give you a range and tell you what would move it. We will not give you a firm number before seeing the building, because it would not be a real number.
Is monitoring required?
Not always. It depends on your insurance requirements and on whether anyone would actually respond to an unmonitored alert. We will tell you when it is worth it and when it is not.
Do I own the equipment?
On our quotes, yes. There is no long-term equipment lease.
Can the work be phased?
Yes, and for larger sites it usually should be. We sequence so that the highest-risk areas are covered first and each phase is a working system rather than a half-finished one.
Are there grants or funding for this?
Sometimes, particularly for nonprofits and in specific state programs.
