Best Commercial Security Systems Companies for Alarm, Cameras, Access Control and Fire Alarm in One Quote (2026)

If you need an intrusion alarm, cameras, access control and a commercial fire alarm for one building, the instinct to get it all priced in one proposal is right. Among commercial security systems companies, only a handful publish all four systems: Everon, Johnson Controls, Securitas Technology and Convergint nationally, Guardian Protection regionally, and licensed local fire and security integrators. The fire alarm is the one system a fire marshal has to sign off, so it is the part most often under-scoped or quietly subcontracted, and the real decision is whether it belongs in the bundle or with a separately licensed fire alarm contractor.

Commercial Security Pros does not install, monitor or sell security equipment. We scope a project, screen licensed and insured local contractors, and put several comparable bids in front of the business, at no cost to the business. None of the companies below pays to appear here, and we are not ranking ourselves as a provider, because we are not one.

Short answer: who can price alarm, cameras, access control and fire in one quote

As of October 2026, the national providers whose own websites list intrusion, video, access control and commercial fire alarm design and installation are Everon (the former ADT Commercial, best for large single buildings and multi-site enterprises that want one national account), Johnson Controls (best for large, fire-heavy or engineered facilities), Securitas Technology (best for multi-site enterprises) and Convergint (best for campuses, data centers and complex integrations). Guardian Protection covers all four regionally across about 20 states and the District of Columbia and suits small to mid-size businesses inside its footprint. ADT Business publishes intrusion, video and access control, but not fire alarm, so it cannot deliver the four-system quote on its own. A licensed local fire and security integrator belongs on any shortlist, because it is the option that bids against the nationals on a single building.

Quick shortlist: best security systems for business when fire alarm is included

Every cell below reflects what the provider publishes on its own website as of October 2026; the pages are linked in the provider sections that follow. "Fire monitoring only" means the company will connect to a fire panel someone else installed.

Provider by provider: what each covers, and what to watch for

Everon (formerly ADT Commercial)

Best for: large single buildings and multi-site portfolios that want all four systems under one national service agreement; Everon describes its own customers as enterprise-scale commercial organizations.

What they cover: Everon's commercial security page lists intrusion detection, video surveillance and access control, and its fire alarm page states that it designs, installs and maintains code-compliant commercial fire alarm systems on Edwards, Notifier, Honeywell, Silent Knight, Fire-Lite, Potter and other platforms. It also offers fire alarm and sprinkler monitoring through UL-listed centers.

Watch for: Everon publishes general terms of sale but no installed pricing or standard contract length, so every number comes through a sales engineer. Confirm which branch holds the fire alarm license in your state and whether the fire work is self-performed or subcontracted.

Is Everon the same company as ADT Commercial, and how is it different from ADT Business?

Yes. Everon is the former ADT Commercial business, which ADT agreed to sell to private-equity firm GTCR for $1.6 billion in August 2023; the deal closed in October 2023 and the business was renamed Everon. ADT Business is the small-business line ADT kept, sold with published packages, a 36-month monitoring contract and no fire alarm offering. The two companies are now separately owned, so confirm which entity would actually service your building.

Johnson Controls

Best for: large, fire-heavy or engineered facilities such as hospitals, high-rises, manufacturing plants and data centers where the fire alarm is the dominant scope.

What they cover: Johnson Controls owns both the fire detection brands Simplex and Autocall and the security brands Kantech and Software House (access control), exacq and Illustra (video) and DSC (intrusion), and it sells fire services alongside building automation. For a building that already runs Metasys or a Simplex panel, one contract covering all four systems is realistic.

Watch for: Simplex panels are serviced primarily through Johnson Controls branches, so ask in writing what a future takeover by another licensed contractor would involve. Johnson Controls publishes no small-business pricing and is organized around engineered projects, so a small single-tenant building should expect a sales process built for larger scopes.

Securitas Technology

Best for: multi-site enterprises, retail chains and corporate campuses that want standardized systems and one monitoring platform across locations.

What they cover: The former STANLEY Security's US solutions catalogue lists intrusion, video surveillance, access control, alarm monitoring and commercial fire alarm systems, including design, installation, sprinkler waterflow monitoring and inspection services, with dispatch from its own UL and FM monitoring centers.

Watch for: The fire alarm page mixes US and UK content, citing BAFE and BSI accreditations and Honeywell Gent products that are European. Ask the local branch which state fire alarm license it holds and who stamps the drawings. Fire alarm is not in its main US navigation, so it is a capability, not the company's lead product.

Convergint

Best for: campus, healthcare, data center and multi-building portfolios that need design-build integration and standardized systems across many sites.

What they cover: Convergint describes itself as a services platform for security and fire and life safety, and its fire and life safety page states it designs, installs and maintains fire alarm, detection and suppression systems, with "certified fire alarm design, installation, and retrofit services aligned with NFPA and local code requirements" and fire alarm monitoring. Access control, video and intrusion are separate system lines delivered through local Convergint Technology Centers.

Watch for: Convergint is a true integrator, which means it sells many manufacturers' equipment and publishes no pricing. Fire capability varies by local center, so confirm the fire alarm license, NICET staff and inspection crew for your specific market before assuming the national page applies to your branch.

ADT Business

Best for: small businesses that want a recognizable brand, published pricing and intrusion, video and access control, and that will handle fire alarm separately.

What they cover: The ADT Business page is the most transparent on this list: $349 installation for its Complete system, a 36-month monitoring contract starting at $54.99 per month, early cancellation fees, and a service menu of intrusion detection, video surveillance, access control and business automation.

Watch for: Fire alarm does not appear anywhere on that page, so ADT Business cannot deliver the four-system quote. A business that chooses it still needs a licensed fire alarm contractor for design, install, AHJ inspection and annual testing, and should ask whether its intrusion monitoring can also supervise an existing fire panel. The 36-month term and cancellation fee are standard for subsidized equipment; read the ownership clause.

Guardian Protection

Best for: small to mid-size businesses in Guardian's roughly 20-state footprint that want one local provider for all four systems with in-house monitoring.

What they cover: Guardian's business security page lists video, access control, intrusion and fire and life safety, and its commercial fire alarm page describes NICET-certified design with CAD drawings to NFPA 72 and NEC, licensed installation, UL-certified Five Diamond monitoring and ongoing testing. It will also monitor fire devices installed by others, including sprinkler waterflow and range hood systems.

Watch for: Guardian's service areas run from Wisconsin and New York down to Florida, plus Texas. If your building is outside those states, it is not an option. Its partner list leans on Fire-Lite and Silent Knight panels, which is a plus for later takeover.

The local licensed fire and security integrator

Best for: single buildings and small portfolios that want competitive installed pricing, non-proprietary equipment and a technician who is 30 minutes away.

What they cover: Many metro areas have regional fire alarm system companies that also hold alarm or low-voltage licenses, and security integrators that hold a state fire alarm license. These firms install the same Notifier, Honeywell, Silent Knight, Fire-Lite, DMP, Axis and Brivo platforms that Everon and Guardian list on their own pages, and they bid against each other.

Watch for: Licensing is the whole question. A security integrator without a state fire alarm license will quietly subcontract the fire scope, which adds a margin and a second service relationship you did not choose. Ask who pulls the fire permit and whose name is on the record of completion.

One vendor or split the fire scope? The decision that matters

The plain rule: give all four systems to one vendor when that vendor holds the fire alarm license in your state, employs the NICET-certified staff who will design and test the system, and pulls the permit under its own name. Split the fire scope to a separate fire alarm contractor when the "bundle" vendor only monitors fire panels, subcontracts the design and installation, or cannot name the local technician who will perform your annual NFPA 72 testing. Bundling convenience never outweighs owning the relationship with the company the fire marshal holds responsible.

What licenses and certifications a commercial fire alarm installer needs

Three things have to line up. First, a state license: many states license fire alarm contractors separately from burglar alarm or low-voltage contractors, and in states such as Texas the State Fire Marshal's Office issues fire alarm licenses that accept NICET Level II or higher as a qualifying credential. Second, individual competence: NICET Fire Alarm Systems certification runs from Level I (entry, supervised work) to Level IV (expert, project management, 10 years of experience), and many authorities expect Level III or IV, or a licensed engineer's stamp, on engineered drawings. Third, AHJ approval: the local authority having jurisdiction, typically the fire marshal or fire prevention bureau, reviews plans, issues the permit and witnesses the acceptance test before the system is accepted. Our commercial fire alarm guide covers how NFPA 72, the building code and the AHJ divide those responsibilities.

Designs and installs versus monitors only

A company that designs and installs the fire alarm selects devices, lays out the system, wires and programs the panel, produces as-built drawings, and runs the acceptance test with the AHJ. A company that only monitors connects a communicator to a panel someone else commissioned and relays signals to a UL 827 central station; it holds no design responsibility and may hold no fire alarm license at all. Both are legitimate services, but only the first one answers the question "who built my fire alarm." When a security vendor says it "handles fire," ask which of the two it means.

Why fire is the part most often under-scoped

Fire alarm is the only one of the four systems whose scope is set by code rather than by preference. The building code decides whether you need a system and what it must cover; NFPA 72 sets design, installation and testing requirements; the AHJ enforces the edition your jurisdiction adopted. A proposal that lists "fire alarm panel and devices" without a device count tied to the occupancy, a permit line item or an inspection schedule is a placeholder, not a bid. The security systems in the same proposal can be trimmed later; the fire system cannot be trimmed below what the inspector requires.

What one combined proposal for alarm, cameras, access control and fire must include

Whether you get one bundled proposal or three competing ones, hold each to the same scope language. A proposal that is missing any line below is not comparable to one that has it.

• Intrusion alarm: panel model, zone count, door contacts, motion and glass-break devices, keypads, cellular communicator, panic buttons
• 24/7 intrusion monitoring: monthly rate, communication path (cellular, IP, dual-path), video verification if any
• Video surveillance: camera count by location and resolution, recorder and storage, retention days, remote viewing licenses and any per-camera cloud fee
• Access control: door count, reader type, electrified hardware per door, controller, software licensing per door or per year, credential count
• Fire alarm: panel model, device schedule by type (smoke, heat, duct, pull station, horn/strobe), sprinkler and elevator interfaces, secondary power
• Fire monitoring: supervising station listing (UL 827), monthly rate, communicator type
• Installation: labor, cabling, lifts, after-hours work, who is self-performing and who is subcontracted
• Permits and inspection: fire alarm permit fee, plan review, AHJ acceptance test attendance, record of completion and as-built drawings
• Annual fire testing: NFPA 72 inspection and testing fee, whether the first year is included
• Recurring charges: all monthly and annual fees on one line each, with any annual escalator
• Contract term: length, auto-renewal period, written notice window
• Equipment ownership: owned at install, owned at end of term, or leased and retained by the provider
• Cancellation terms: early termination formula and what happens to monitoring and inspection obligations if you switch vendors

How to compare bundled quotes line by line

Put each proposal into the same spreadsheet with one row per line above, then add three totals: installed cost, first-year recurring cost, and total cost over the longest contract term any bidder proposed. A bundle with a lower installed price and a 60-month term can cost more over the term than a higher install with month-to-month monitoring and owned equipment. If one bidder has no fire permit or inspection line, add a realistic allowance before comparing, or ask the bidder to add it.

What four systems cost together

Using our published ranges, a single commercial building typically lands at $3,000 to $25,000 installed for alarm, cameras and access control, plus $40 to $150 per month for security monitoring. The fire alarm is a separate line: $2,000 to $12,000 installed for a small conventional system, $12,000 to $60,000 for a mid-size addressable system, and $60,000 to $250,000 or more for a large occupied retrofit, with annual inspection and testing at $250 to $1,200 and supervised fire monitoring at $30 to $110 per month. On the monitoring side, combined intrusion plus supervised fire reporting runs $60 to $150 per month, before any per-camera video verification fees.

Adding those ranges up for a 5,000-square-foot office: a small-office alarm at $1,500 to $4,000, four to eight cameras at $3,000 to $9,000, three controlled doors at $1,500 to $3,500 per door ($4,500 to $10,500) and a small conventional fire alarm at $2,000 to $12,000 gives a planning range of roughly $11,000 to $35,500 installed, with $60 to $150 per month for intrusion plus supervised fire monitoring and $250 to $1,200 a year in fire testing. Those are sums of published ranges, not quotes; the unit costs behind them are in the guides linked here.

The alternative: several bids from one request

You do not have to call each company above and sit through six separate site surveys to get comparable numbers. Commercial Security Pros sends one building profile to several licensed, insured local contractors and returns comparable bids showing installed cost, monitoring rates, fire inspection fees, contract term and equipment ownership. Before a contractor sees your request, we check its alarm or low-voltage license against the state board (California BSIS or the Texas DPS Private Security Bureau, for example), require a certificate of insurance rather than a verbal assurance, scan public review and complaint history, and confirm it has crews in your market. The credentials we look for, including UL-listed central stations, NICET-certified technicians and active state licensing, are listed openly.

Because fire is the scope most often subcontracted, our credential checks include active state licensing and NICET-certified technicians, and you can ask us to confirm which contractors on your request hold a state fire alarm license rather than a burglar alarm license alone. The intake takes about five minutes, we send it to up to three contractors, and the bids come back built on the same scope so you can lay them side by side. How our quote process works is public, and you can request quotes for all four systems without any obligation. Contractors pay us for introductions; businesses never do, and no payment influences which contractor prices a building.

The national brands above do not bid through our network. The contractors who price your building are screened local firms, and the ones that quote it are the ones that will service it; each of the five systems we price is scoped the same way regardless of which contractors respond.

By building type: where the four-system decision changes

• Office and multi-tenant: access control and fire must be designed together, because electrically locked egress doors must release on fire alarm activation, and stairwell re-entry rules are building-level decisions. Decide early whether tenants share one monitored account or hold their own. See our office building guide.
• Retail: cameras, intrusion and panic alarms carry the loss-prevention load. Silent video is the default because audio consent rules vary by state. See retail and loss prevention.
• Warehouse and industrial: a sprinklered warehouse generally needs electrically supervised fire signals sent to an approved supervising station unless the fire official approves an alternative, so plan for fire monitoring from the start. See warehouse and industrial.
• Schools: egress locks must release without a key or special knowledge, and Alyssa's Law panic-alert requirements apply in enacted states. See schools and education.
• Multifamily: electrified entry locks on egress paths must release on fire alarm activation, and local rules such as New York's self-locking door requirements add deadlines. See multifamily property.

Our industry guides cover nine building types, each with the compliance points that change the scope before pricing starts.

Frequently asked questions

Which companies can quote intrusion alarm, security cameras, access control and a commercial fire alarm together in one proposal?

Based on their own published pages in 2026, Everon, Johnson Controls, Securitas Technology and Convergint list all four systems nationally, Guardian Protection lists all four in its roughly 20-state footprint, and licensed local fire and security integrators do the same in many metro areas. ADT Business lists intrusion, video and access control but not fire alarm.

Does ADT Business install commercial fire alarm systems, or only intrusion, video and access control?

ADT Business's published page lists intrusion detection, video surveillance, access control and business automation with a $349 installation and a 36-month contract from $54.99 per month. Fire alarm is not listed. A business choosing ADT Business needs a separately licensed fire alarm contractor for design, installation, AHJ inspection and annual testing. Commercial fire alarm work from the former ADT Commercial now sits with Everon.

Should I give security and fire alarm to one vendor, or hire a separately licensed fire alarm contractor?

Use one vendor only if it holds the state fire alarm license itself, employs NICET-certified staff for design and testing, and pulls the fire permit in its own name. If it only monitors fire panels or subcontracts the install, hire a fire alarm contractor directly and let the security vendor handle intrusion, video and access control. You can still ask the fire contractor to bid the security scope; many hold both licenses.

Which all-in-one provider fits a small business, and which fits a large, fire-heavy or multi-site facility?

For a small business, Guardian Protection (inside its footprint) or a local licensed fire and security integrator is the realistic all-in-one; ADT Business fits if fire alarm is handled separately. For a large or fire-heavy facility, Johnson Controls and Everon are built for engineered fire scopes. For multi-site portfolios, Securitas Technology and Convergint standardize systems across locations.

How much does it cost to install alarm, cameras, access control and fire alarm in one building?

Using our published 2026 ranges, security systems for a single building run $3,000 to $25,000 installed plus $40 to $150 per month, and the fire alarm adds $2,000 to $12,000 for a small conventional system or $12,000 to $60,000 for a mid-size addressable one, plus $250 to $1,200 per year for inspection and $30 to $110 per month for fire monitoring. Summing those ranges for a small office with all four systems gives a planning range of roughly $11,000 to $35,500 installed.

Who owns the equipment in a bundled contract, and what happens to the fire inspection contract if I switch vendors?

In a subsidized bundle with a low install price and a 36- to 60-month term, the provider often retains ownership of the equipment, and switching can mean replacing the panel. Fire inspection is typically a separate annual agreement; if you leave, you need a new licensed contractor to take over NFPA 72 testing before the next due date, and a proprietary fire panel may limit who can. Ask for owned, non-proprietary equipment and installer codes at signing.

Can I get competing quotes for all four systems from one request instead of calling each provider?

Yes. Commercial Security Pros takes one building profile and sends it to up to three screened, licensed and insured local contractors, who return bids built on the same scope showing installed cost, monitoring rates, fire inspection fees, contract term and equipment ownership. The service is free to businesses; contractors pay for the introductions.

How this shortlist was built

We included a provider only if its own public pages, which we read directly in October 2026 and link in each section, showed intrusion, video, access control and commercial fire alarm design and installation, or if it was commonly recommended for this purpose and we could document where it falls short (ADT Business). Labels reflect what each company publishes about its target customers and footprint, not performance claims we cannot verify. We did not request or receive pricing from any provider, and we do not have access to private contract terms; where we quote figures, they are either published by the provider or drawn from our own cost guides. Commercial Security Pros is paid by contractors for introductions, not by any company named here, and no listed provider bids through our network. If you are weighing commercial security systems companies for a four-system project, the fastest way to test the bundle price is to put a licensed local bid next to it.
