Commercial security system cost in 2026
Commercial security system cost runs $3,000 to $25,000 installed for most single-building businesses, plus $40 to $150 a month for monitoring. A small business under 5,000 square feet lands at $3,000 to $10,000, a 5,000 to 25,000 square foot building at $10,000 to $50,000, and a large or multi-building site at $50,000 to $150,000 and up. That is roughly $1 to $5 per square foot. Door count and camera count drive it, not floor area.

The numbers
Commercial security system cost by building size
Ballpark installed and recurring pricing for planning. Real commercial security system quotes vary by building, market and scope, which is why you get more than one.
| Building | Installed | Monitoring | What is typically included |
|---|---|---|---|
| Small business: under 5,000 sq ft | $3,000 – $10,000 | $40 – $120/mo | Commercial alarm panel, contacts on every perimeter opening, two to four motion detectors, glass-break on storefront glass, a cellular communicator, and 4 to 8 cameras on one recorder at 30-day retention. One or two access-controlled doors push you to the top of the range. Alarm alone, with no cameras, starts near $1,500. |
| Mid-size: 5,000 to 25,000 sq ft | $10,000 – $50,000 | $100 – $300/mo | Partitioned alarm zones so areas arm separately, 8 to 24 cameras with exterior coverage and 30 to 90 days of retention, and typically 4 to 12 access-controlled doors. Conduit, lift work, and cable to a second floor or a detached structure are what move this tier, not the device list. |
| Large or multi-building: 25,000+ sq ft | $50,000 – $150,000+ | $250 – $1,000+/mo | Multiple panels or one partitioned commercial panel, 24 or more cameras, 90+ day retention, access control on most doors, a head-end with redundant storage, and usually a written design. Multi-site rollouts and integrated fire alarm push past $150,000. |
Planning ranges, not quotes. They cover intrusion alarm plus video, with access control at the upper end of each tier. Four independent 2026 guides put a small commercial system between $3,000 and $10,000 and a mid-size one between $8,000 and $50,000. The widest disagreement is at the small end: one regional guide starts a single-suite intruder alarm at $500 to $2,000, and one business-media guide puts basic hardware at $1,500 to $3,000 before a $300 to $700 installation charge. Monitoring here is the central station on the intrusion system; cloud video and access control licensing are separate lines.
Per unit
Commercial security system cost per unit
Project totals hide the arithmetic. These are the unit prices a quote is built from, so you can check whether a total is honestly sized before you compare it to another.
| Item | Typical range | Notes |
|---|---|---|
| Per square foot, installed | $1 – $5 | Derived from the building tiers above for a retrofit of alarm plus cameras: a 5,000 sq ft office at $5,000 to $15,000 is $1 to $3 per square foot. Integrators budgeting security into new commercial construction quote higher, $3 to $15 per square foot for access control and video designed in from the drawings, with $3.50 to $6.00 the figure most often cited by working integrators. Treat this as the least reliable unit on the page. Two buildings of the same size with different door counts price nothing alike. |
| Per alarmed opening (door or window contact, installed) | $75 – $250 | The contact, its supervision, and the labor to mount and program it. One business-media guide puts burglar alarm sensors at $75 to $600 each; a regional installer quotes $100 to $200 for each device added to an entry-level system. Overhead doors, roll-up doors, high windows, and openings behind finished walls land at the top of the band or past it. |
| Per camera, installed | $300 – $1,500 | Standard commercial IP domes and turrets cluster at $500 to $900 installed. 2026 installer guides quote $300 to $600 for a standard commercial camera, $600 to $1,200 for 4MP to 8MP, and $1,200 to $2,500 and up for analytics or specialty units. Warehouse work that needs a lift runs $1,000 to $1,500 per camera once labor is counted. |
| Per access-controlled door, installed | $1,200 – $3,500 | Reader, controller, lock hardware, power, and cabling on one door. Four 2026 guides land at $1,200 to $2,500, $1,500 to $3,000, $2,500 to $3,500, and $2,500 to $5,000, and working integrators budget $2,000 to $3,000 per door for early estimates. Mag-lock and high-security doors run $2,500 to $4,500. One guide quotes $800 to $1,200 per door, which describes a keypad on an existing lock rather than a managed credential system. |
| Central station monitoring, per month | $40 – $150 | UL-listed monitoring on a commercial intrusion system. App-based plans with no staffed station run $24 to $60. High-priority response tiers run $60 to $150. Large or multi-panel buildings run $150 to $400. Published national business packages sit at $53.99 to $69.99 a month on a 36-month agreement. |
| Installation labor, per hour | $75 – $150 | Low-voltage crew rate. One integrator guide quotes $75 to $150 per hour, another bills security installation at around $150 per hour. Cable is often quoted per run instead, at $150 to $300 a drop. |
| Cloud video recording, per camera per month | $10 – $30 | 30-day retention at 1080p to 2K. Separate from alarm monitoring and separate from access control licensing. An on-premise recorder has no line here at all, which is why two quotes can look similar on install and diverge badly over five years. |
| Access control licensing, per door per month | $14 – $75 | Cloud-managed platforms only: $14 to $20 entry-level, $25 to $40 standard, $40 to $75 enterprise. An on-premise controller carries no per-door fee but does carry a software maintenance agreement. Ask which model the quote assumes before comparing monthly totals. |
What moves the price
What drives commercial security system cost
In order of how much they move the number. If two quotes for the same building differ by more than a third, one of these is usually the reason.
- 01
How many of the five systems you are actually buying
The single biggest reason two commercial security system quotes differ by ten times is that they are not quoting the same thing. Intrusion alarm, video surveillance, access control, central station monitoring, and fire alarm are five separate systems, and published ranges usually cover one or two of them. Intrusion alone is $1,000 to $5,000 for most small buildings. Video is $2,500 to $8,000 for a small camera count. Access control is $1,200 to $3,500 per door. Fire alarm is its own budget, typically $2,000 to $10,000 and up, and is required by code rather than chosen. Write down which systems you want before you collect quotes, because the cheapest number in your inbox is usually the one covering the least.
- 02
Openings, doors and cameras, not square feet
Floor area is a poor predictor. A 4,000 sq ft storefront with a glass front, a back door, a roll-up, and a stockroom can carry more devices than a 12,000 sq ft warehouse with two doors and no windows. The count that matters is perimeter openings to alarm, doors to control, and viewpoints to cover. Integrators themselves say per-square-foot budgeting is unreliable for exactly this reason and use per-door math for early estimates. Do the counts yourself before the first site visit and give every bidder the same list.
- 03
Cabling and site conditions
Labor and pathways are where identical device lists become different prices. A drop through an accessible ceiling is a short pull. The same device on a masonry exterior wall means conduit, anchors, and a lift. Trenching to a gate or a detached building is its own line and is frequently larger than the hardware at the end of it. Cable drops run $150 to $300 each, and several 2026 guides name cabling and site conditions as the largest source of variance between quotes on the same building. Ask every bidder to state what they assumed about ceiling access, exterior conduit, lift time, and trenching.
- 04
National provider versus local licensed installer
The same building gets two differently shaped quotes. A national provider typically publishes a package: a subsidized equipment and installation figure, sometimes a few hundred dollars for a small business kit, attached to a 36-month monitoring agreement at roughly $54 to $70 a month. A local licensed integrator typically prices equipment and labor at cost plus margin, so the install number is larger, and monitors at a separate rate. Across 36 months the totals can land close together. What differs is what you own and what you can change later. Ask both the same three questions: who owns the panel and the sensors when the term ends, is the panel programming locked to the installing dealer, and what does the agreement renew into. Subsidized equipment is a financing arrangement. That is neither good nor bad, but price it as one.
- 05
Retention window on video
Storage is the line that quietly doubles a camera budget. Continuous recording needs roughly 1 TB per camera per month at 1080p and about 2 TB at 4K, so retention is a hardware decision before it is a policy decision. Decide the window first, from your insurer, your regulator, or your own incident history, then size the recorder or the cloud plan to it. A quote listing cameras but hedging on days of retention cannot be compared with one that does not.
- 06
The monitoring agreement, not the install price
Commercial monitoring agreements commonly run 36 to 60 months with automatic renewal unless you cancel inside a notice window. At $100 a month, 60 months is $6,000, which on a small building can exceed the installed price. Compare total cost of ownership over the term: installed price, monthly rate, term length, renewal terms, any annual escalator, and who owns the equipment at the end. A proprietary panel with locked programming means every future quote has to come from the company that installed it, which is a price you pay later rather than now.
By region
Commercial security system cost by region
Hardware costs roughly the same everywhere. What moves commercial security system cost by city is labor, the wiring method the local electrical code requires, whether a permit is pulled, and which license the state demands of the installer. The figures below are wage and code facts from primary sources, not multipliers we invented. Verify permit, licensing, and alarm ordinance rules with your city building department, your police department, and your state licensing agency before you sign anything.
Labor wage variation by metro
The BLS May 2023 Occupational Employment and Wage Statistics survey puts the national mean wage for security and fire alarm systems installers at $27.59 per hour. The highest-paying metros are San Jose-Sunnyvale-Santa Clara at $41.40, San Francisco-Oakland-Hayward at $38.03, Minneapolis-St. Paul-Bloomington at $37.07, Eugene at $36.52, and Salem at $34.85. By state the top means are Minnesota $36.15, Washington $33.72, Oregon $33.71, Alaska $33.38, and Maryland $32.92. A crew rate of $75 to $150 per hour tracks that spread, and labor is a large share of any install, so the same device list prices differently in San Jose than in a low-wage metro.
Chicago: conduit and low-voltage permits
The Chicago Department of Buildings permit guide states that installing or removing a low voltage electrical fixture such as a security camera does not require a building permit, but that a building permit is required for the installation of low voltage wiring. The city's own electrical training material lists metallic conduit requirements and limits on communication cable in plenums as key Chicago amendments to the electrical code, with flexible metal conduit allowed behind existing walls and hard-surface ceilings in lengths up to 25 feet. Budget for EMT on exposed runs and for a permit on commercial wiring, and confirm the current rules with the Department of Buildings.
State alarm and low-voltage licensing
Which license an installer must hold varies by state, and in some states by county or city. Some require a state alarm or burglar alarm contractor license, some fold the work into an electrical or limited-energy license, and some add company registration plus individual technician registration with background checks. There is no national number to quote here, which is the point: check the specific board in the state where the building sits, and ask for the license number rather than a logo on a website.
Alarm permits and false-alarm ordinances
Most municipalities require a business alarm permit and fine for repeated false dispatches, and the schedules differ sharply. San Antonio, as one published example, charges nothing for the first three false burglar alarms at a permitted location, then $50 for the fourth and fifth, $75 for the sixth and seventh, and $100 after that, while an unpermitted commercial burglary false alarm is $250 and an unpermitted commercial robbery false alarm is $500. Panic and robbery alarms escalate faster than burglar alarms in most cities. This is not a line item on your quote, but it is a real operating cost. Look up your own city's ordinance before the system is armed for the first time.
Prevailing wage and public projects
Schools, municipal buildings, and other publicly funded work can trigger prevailing wage requirements, which raise the labor line on an identical device list. Ask each bidder whether their number assumes prevailing wage, and whether certified payroll is included in their price.
Sources
How we got these numbers
Ranges were built in four passes. First, eight independent guides published between September 2024 and September 2026 (five commercial integrators in different regions, one national alarm company, one business-media outlet, and one industry discussion among working integrators) were read for system totals, per-door, per-camera, per-sensor, labor, and monitoring figures. Where at least four of them overlapped, the overlap became the published range; where one sat outside the rest it is named in the per-unit note rather than averaged in. Second, a national provider's published business package pricing was read as the subsidized-equipment comparison point, because that pricing model is what most buyers are comparing a local integrator against. Third, the resulting tiers were checked against the figures already published on this site's home page and alarm systems service page, which they match: $3,000 to $25,000 installed for most businesses and $30 to $150 a month. Fourth, the per-square-foot figure was derived from the building tiers rather than lifted from a vendor, because only one usable published source quotes security per square foot and it describes new construction. Sources disagree most on three points. Per access-controlled door: $800 to $1,200 at the low end against $2,500 to $5,000 at the high end, a gap explained by whether the quote is a keypad on an existing lock or a managed credential system with lock hardware. Small business totals: one regional guide starts a single-suite intruder alarm at $500 while several others start a small commercial system at $3,000, a gap explained by device count and by whether cameras are included. Per square foot: $0.50 to $1.00 is a fire alarm figure and does not apply to security, while $3 to $15 comes from new-construction budgeting that includes access control on most doors. All figures are planning ranges. Site conditions decide the real number, which is why the only honest recommendation is three quotes on one written scope.

Straight answers
Commercial security system cost, FAQ
How much does a commercial security system cost?
$3,000 to $25,000 installed for most single-building businesses, plus $40 to $150 a month for monitoring. A small business under 5,000 square feet lands at $3,000 to $10,000, a 5,000 to 25,000 square foot building at $10,000 to $50,000, and a large or multi-building site at $50,000 to $150,000 and up. The spread is physical: openings to alarm, doors to control, cameras to run cable to, and how long you keep footage. A building priced without those counts has not been priced.
How much does a commercial security system cost per month?
$40 to $150 a month for UL-listed central station monitoring on a typical commercial building. App-based plans with no staffed station run $24 to $60, high-priority response tiers run $60 to $150, and large or multi-panel facilities run $150 to $400. Cameras and access control add their own recurring lines: $10 to $30 per camera per month for cloud recording and $14 to $75 per door per month for cloud-managed access control. Add those up before comparing two monthly rates, because one quote may be carrying all three and the other only one.
How much does a commercial security system cost per square foot?
$1 to $5 per square foot for a retrofit of alarm plus cameras in an existing building, and $3 to $15 per square foot when access control and video are designed into new commercial construction. Working integrators say $3.50 to $6.00 is what they actually spend on construction projects. Be careful with this number. The widely quoted $0.50 to $1.00 per square foot is a fire alarm figure, not a security figure. And two buildings of the same size with different door counts price nothing alike, which is why integrators budget per door rather than per square foot.
How much does a small business security system cost?
$3,000 to $10,000 installed for a small business under 5,000 square feet with alarm and cameras, or roughly $1,500 to $4,000 for the alarm alone. Monitoring adds $40 to $120 a month. National providers sell subsidized packages instead, often $400 to $1,200 for equipment and installation attached to a 36-month agreement at $54 to $70 a month, which is a financing arrangement rather than a cheaper system. At the small end the contract matters more than the hardware: over 36 months the monitoring line frequently exceeds the install.
How much does a commercial security system with cameras cost?
Add $3,000 to $9,000 to the alarm for 4 to 8 commercial IP cameras with one recorder and 30-day retention, and $9,000 to $35,000 for 8 to 24 cameras. Per camera that is $300 to $1,500 installed, with most standard commercial cameras at $500 to $900. So a small business running alarm plus cameras lands at $3,000 to $10,000 all in, and a mid-size building at $10,000 to $50,000. Retention window drives the recorder and the storage, so decide how many days of footage you need before anyone quotes the camera count.
Should I use a national provider or a local licensed installer?
It depends on what you want to own. A national provider typically subsidizes equipment and installation and recovers it through a 36-month monitoring agreement at roughly $54 to $70 a month. A local licensed integrator typically charges more up front and less, or separately, per month. Over three years the totals can be close. What differs is equipment ownership, whether the panel programming is locked to the installing dealer, and how the agreement renews. Get both to answer those three questions in writing, then compare total cost over the full term rather than comparing the install prices.
What should a commercial security system quote include?
A device schedule, a labor assumption, and a contract summary. Device schedule means the count of alarmed openings, motion detectors, glass-break detectors, cameras with their resolution and retention window, and access-controlled doors with the lock hardware named. Labor assumption means what the bidder assumed about ceiling access, exterior conduit, lift time, and trenching, because that is the largest single source of variance between quotes. Contract summary means the monthly rate, the term, the renewal terms, and who owns the equipment at the end. Any quote missing those three cannot be compared to one that has them.
Do I need a permit for a commercial security system?
Usually two different ones, and both are local. On the install side, some cities require a building or electrical permit for low-voltage wiring: Chicago, for example, requires a building permit for the installation of low voltage wiring even though the camera itself needs none, and its electrical code amendments require metallic conduit in many locations. On the operating side, most municipalities require a business alarm permit before police will respond, and fine for repeat false alarms. Ask whether permits are in the quoted price and verify both with your city.
