Security System Technician: Alarm, CCTV and Intrusion Installer Careers

A security system technician installs, programs, services and tests the electronic systems that protect buildings: intrusion and burglar alarms, video surveillance (CCTV), access control and the integrated software platforms that run them together.

One day the job is a new commercial install; another day it is a service call on a system someone else commissioned years ago, or an upgrade that ties an aging panel into a newer network.

The mechanical arc of the work repeats across system types: pull and dress the cabling, mount the devices, terminate, program the panel or head end, then test everything and walk the customer's staff through it.

Service technicians then live on the follow-up — diagnosing faults, replacing failed devices and keeping systems online.

The role travels under many names.

BLS lists Alarm Technician and Burglar Alarm Installer among the example titles for the occupation it publishes this work under — security and fire alarm systems installers, SOC 49-2098 — and other names for versions of the same job include security alarm technician, burglar alarm technician, electronic security technician and CCTV technician.

Searching all of them is part of finding work in this trade.

The published numbers worth calibrating against: BLS counted 86,340 jobs nationally in SOC 49-2098 as of the May 2025 OEWS, with a median wage of $28.88 an hour ($60,070 a year); the 10th percentile earned $38,800 and the 90th $81,150.

The work falls into four system families, and a single project can include all four.

• Intrusion and burglar alarm — control panels, door and window contacts, motion detectors, glass-break sensors, keypads and the communicators that report alarms to a monitoring center. This is the classic alarm-technician core.
• Video surveillance (CCTV) — camera placement, mounting and aiming, recorders and video management software, and the network cabling and switches modern cameras ride on. Closer to IT work than it looks from the outside.
• Access control — card and fob readers, door controllers, electric strikes and magnetic locks, request-to-exit devices and the credential-management software behind them.
• Integrated systems — the platforms that pull intrusion, video and access into one interface, tied to monitoring and to the customer's network. Integration work is where the commercial integrators in the next section live.

All of it is signal work rather than building power — the low-voltage side of the electrical trades.

Where each state draws the line between security wiring and work that belongs to a licensed electrician varies, which is why the licensing question below deserves a real answer before you accept a job.

For the wider branch — structured cabling, fire alarm, AV and how the roles relate — see the low voltage technician career guide.

The same skills look like two different jobs depending on who employs you, and it is worth deciding which world you are aiming at.

Residential security dealers install intrusion alarms, cameras and smart-home add-ons in customers' homes.

The rhythm is short back-to-back installs plus steady service calls: a van stocked with common parts, customers who want the system explained plainly, and the most customer-facing version of the trade.

It is also a fast way to see many different systems in your first years.

Commercial integrators design and install access control, video and intrusion for offices, schools, hospitals, warehouses and data centers.

The work is project-based: drawings and submittals, coordination with general contractors and the customer's IT team, staged installation while the building is fitted out, then commissioning.

The pace is slower per job, the systems bigger, and the documentation burden heavier.

Between them sit the electrical and low-voltage contractors whose security scope arrives attached to a larger electrical contract, and the campuses, hospitals and facilities that employ in-house technicians to run their own systems.

Which world pays better has no published answer in our sources — BLS reports the occupation as one group, SOC 49-2098 — so weigh an offer against the median and percentiles above rather than a dealer-versus-integrator rule of thumb.

For scale on the industry behind the work: the Electronic Security Association (ESA), founded in 1948, says it is the largest U.S. trade association for the electronic life safety and security industry and that its member companies employ more than 500,000 industry professionals — the association's own figures.

From what our research found, it depends on the state.

We found no standard federal or national rule covering alarm technicians: whether alarm work requires a state license or registration, whether fingerprinting or a criminal-history check applies, what disqualifies, and whether waivers exist appear to be set state by state, and sometimes by cities and counties instead.

The agency matters as much as the rule, because the body that regulates alarm work is not necessarily the state electrical board.

ESA lists some level of licensing or renewal approval for its National Training School courses from agencies including the Texas DPS Private Security Bureau, the Tennessee Alarm Systems Contractors Board, the Florida Electrical Contractors Licensing Board, the New York Department of State and the North Carolina Alarm Systems Licensing Board — a sample of how differently the states organize this.

The list itself spans a Department of Public Safety private security bureau, dedicated alarm systems contractors and licensing boards, a department of state and — in Florida — an electrical contractors licensing board; check which body holds the reins where you plan to work.

Where a state's electrical law does cover the wiring a security system needs, a separate low-voltage or limited-energy license question sits underneath the alarm question — answered by different rules again.

And keep certificate and license straight: a training credential certifies the person, a state agency regulates the work.

See license vs certification for the full sorting.

BLS describes the occupation's typical entry as a high school diploma or equivalent plus moderate-term on-the-job training.

The route in follows that shape: get hired, learn on real systems, add a recognized credential, and check your state's rules before taking alarm work.

Certifications do not substitute for a license where a state requires one — the two answer different questions — but published course and exam requirements make them checkable in a way a list of self-taught skills is not.

And in some cases they do double duty: ESA lists some level of licensing or renewal approval for its National Training School courses from the Texas, Tennessee, Florida, New York and North Carolina agencies named above, with the caveat that approvals depend on each agency's licensing requirements and may not cover every course.

The credential family most specific to this trade comes from ESA's National Training School.

Its certification list runs from Certified Alarm Technician (CAT) Level 1 and Level 2 through Certified Intrusion Technician Level 2, Certified Video Technician, Certified Systems Integrator and Certified Service Technician, with separate fire alarm technician, designer and inspector credentials in the same school.

CAT Level 1 is the entry rung: complete the course, classroom or online, then pass a proctored multiple-choice exam — and note ESA's own caveat that not all state agencies accept online courses for licensing, which matters if a state agency is part of your plan.

Two footnotes save you money.

First, NICET stopped offering Video Security Systems testing after December 31, 2023 — technicians who already hold it can recertify, but there is no current exam for a new candidate to sit, so do not chase one.

Second, platform certifications are dealer-channel credentials: LenelS2's OnGuard certification, for example, is required to access the manufacturer's technical support, and its training is booked through the value-added reseller — so technicians normally pick it up through an authorized dealer or integrator employer rather than on their own.

The employers to check fall into four groups.

Alarm dealers and monitoring companies staff residential and small-commercial installs and service.

Commercial integrators staff commercial projects with project installers, programmers and service technicians.

Electrical and low-voltage contractors bring in security techs when a contract bundles security into a larger electrical scope.

And campuses, hospitals and large facilities keep in-house technicians to run their own systems.

Search broadly: alarm technician, burglar alarm installer, security installer, CCTV technician and electronic security technician are all names for versions of this job — BLS's own example titles for the occupation include Alarm Technician and Burglar Alarm Installer.
