7 Best Security System Installers NYC

The best NYC security installers all nail the install day. The real test comes months later, when something needs fixing and you find out who picks up the phone.

Great hardware is easy to find.

A team that still answers a year later is the rare part.

We checked the reviews, the credentials, and the fine print. Here are the 7 best, who each suits, and what to watch for.

Our Top 3 Best Security Installer NYC Picks

• Best for complex, multi-system commercial properties: Highline Integrated Security
• Best for co-ops & intercom-heavy residential buildings: NYC Intercom & Security Solutions
• Best for high-value sites needing fire compliance & in-house monitoring: DGA Security Systems

1. Highline Integrated Security

Best for: Commercial properties that need reliable installs & the best security installer NYC has for modernizing outdated systems.

Most installers sell you boxes: cameras here, an access panel there, a separate alarm contract. Highline designs the whole system around your building first, then installs every layer (access control, surveillance, intercoms, alarms, the cabling underneath) so it works as one platform.

That matters most in tricky environments, and their track record proves it out: landmark-compliant access control in historic brownstones, security upgrades at Lincoln Center, retrofits that modernize old infrastructure without ripping it out. You get a single team owning the design through to long-term support, not three subcontractors pointing fingers.

Reviews back this up – clients repeatedly cite clean installs, fast turnaround, and honest, no-upsell guidance – which is why they earn the top spot as the best security installer NYC.

Services

• Enterprise access control (card, biometric, smartphone entry)
• IP cameras & surveillance with remote monitoring
• Commercial alarm & intrusion systems
• Multi-tenant intercom & entry systems
• Structured cabling
• Full security system integration
• Legacy upgrades & landmark-compliant installs

Pros

• One team owns design, install, and support – no subcontractor finger-pointing
• Proven on landmark and high-profile NYC projects most installers can’t handle
• Tailored system design built around the building
• Clean, low-disruption installs with fast turnaround and 24/7 support

Cons

• Commercial-forward, so a weaker fit for purely residential jobs

Score: 4.8/5

2. NYC Intercom & Security Solutions

Best For: Co-ops, condos, and multi-tenant residential buildings that want a responsive, intercom-focused specialist and a personal point of contact.

If your project centers on intercoms or access in a residential building, NYC Intercom is hard to beat on service.

Founded in 2005 by Luca Costagliola, it’s a tight, founder-led operation with a genuinely outstanding reputation – 4.9 stars across 222 Google reviews, with property managers repeatedly naming Luca for solving problems other companies walked away from. Weekend callbacks, fast troubleshooting, clean discreet installs, on-budget delivery: the consistency is striking.

Where they’re a narrower fit is scale. This is a boutique specialist strongest on intercom, camera, and access work for buildings – not a multi-site enterprise integrator running fire compliance or 21,000-camera commercial rollouts.

For its lane, though, the reviews speak for themselves.

Services

• Intercom systems (wired, wireless, audio, video)
• Access control (card, biometric, keypad, mantrap)
• Security cameras & CCTV with remote monitoring
• Structured cabling
• Locksmith services
• Customized security solutions

Pros

• Exceptional, consistent service reputation – 4.9/5 across 222 reviews
• Founder-led with a real personal point of contact and fast response
• Deep specialization in intercom and co-op/multi-tenant residential work
• Clean, discreet installs delivered on time and on budget

Cons

• Boutique team scale – less suited to large multi-site or enterprise rollouts
• Intercom/residential-led focus rather than full commercial fire or monitoring
• Smaller technology partner bench than the bigger NYC integrators

Score: 4.6/5

3. DGA Security Systems

Best For: High-value commercial environments (jewelry, galleries, financial, retail) that prioritize monitoring and fire compliance over flexible terms.

DGA is one of the most established names in NYC business security, and where they really separate themselves is monitoring.

They run their own UL-listed, TMA Five Diamond–certified monitoring centers, and they hold the UL 2050 listing for government contractors handling classified material – a credential very few installers carry.

Add NICET-certified fire system design and FDNY approval, and you get a genuine one-stop shop for businesses that need security and fire under serious compliance.

Reviewers, many of them 15-to-30-year clients, consistently praise fast alarm response and dependable systems.

The trade-off is rigidity: expect premium pricing, long contracts (one reviewer flagged a 10-year term), and occasional post-sale communication gaps. Read the fine print before signing.

Services

• Intrusion alarms with UL-listed central station monitoring
• Video surveillance (DGA OneVIEW platform)
• Access control (DGAPass™ – mobile, card, fob, tag)
• Fire alarm design, installation, testing & inspection (NICET/FDNY)
• Environmental & elevator emergency monitoring
• Nationwide multi-location service

Pros

• Own UL-listed, Five Diamond monitoring centers – not outsourced
• UL 2050 government-grade and full FDNY fire credentials
• Exceptional alarm response times cited repeatedly in reviews
• Remarkable client retention, with many relationships spanning decades

Cons

• Premium pricing that undercuts value for smaller or budget-conscious buyers
• Long-term contracts with terms some reviewers felt weren’t clearly explained
• Post-sale communication and issue resolution can lag once installed

Score: 4.4/5

4. Eddie’s Security Systems

Best For: Small businesses and homeowners who want honest, affordable camera and intercom work from an owner-operated team.

Eddie’s competes on something the bigger firms can’t easily replicate – trust at a small-shop scale.

The review profile is genuinely excellent – near-spotless, with customers repeatedly describing the same things: clean hidden wiring, fast same-day service, and honest advice. More than a few mention other companies pushing full system replacements while Eddie recommended a cheaper repair instead.

For a small business or home that wants quality work without enterprise pricing, that’s a strong pitch, and Eddie himself being the point of contact keeps things personal.

The trade-off is scope. This is a lean operation focused on cameras, intercoms, alarms, and access for straightforward properties, not a licensed fire-compliance or multi-site integration partner for complex commercial portfolios.

Services

• Security cameras & remote monitoring
• Access control
• Alarm systems (24/7 monitoring)
• AV & intercom systems
• Phone & network systems (VoIP, wireless)
• Commercial & residential installs

Pros

• Outstanding, near-spotless review profile built on honesty and value
• Genuinely affordable – strong quality-to-price for SMBs and homes
• Clean, detail-oriented installs with hidden wiring praised repeatedly
• Owner-involved service with no-pressure, no-upsell recommendations

Cons

• Small, lean operation – not suited to large or multi-site commercial projects
• Limited scope versus full integrators (no dedicated fire/compliance focus)

Score: 4.3/5

5. Paragon Security & Locksmith

Best For: Property managers and businesses that want a locksmith-rooted security partner with serious 24/7 emergency coverage.

Paragon has been a fixture in NYC since 1988, and its locksmith heritage is the real differentiator.

Where most installers stop at systems, Paragon does high-security locks, master-key setups, safes, and door hardware alongside access control, intercoms, and cameras – useful when a building needs both worlds handled by one team.

The client roster is impressive too (Hilton, NYU, Greystar, Douglas Elliman), and reviewers describe the emergency response as near-legendary: technicians arriving within the hour on holidays and at 1 AM, clean work, named techs people trust.

The recurring catch is cost. Premium pricing and occasional surprise fees come up repeatedly, with the consensus being “expensive, but worth it.”

Best when expectations on price are set upfront.

Services

• Commercial & high-security locksmith, master key systems
• Access control & smart locks
• Commercial intercom systems
• Security cameras & surveillance
• Alarm & intrusion systems
• Security system repair & monitoring

Pros

• 30+ years and a rare locksmith-plus-systems capability under one roof
• Outstanding 24/7 emergency response – fast arrivals, even on holidays
• Strong institutional client roster and long-term repeat business
• Clean, skilled workmanship with technicians customers name and trust

Cons

• Premium pricing and occasional surprise fees are the most cited complaint
• Upfront cost communication can be inconsistent between techs
• Locksmith-led identity rather than a dedicated systems-integration focus

Score: 4.2/5

6. Vertex Security

Best For: Multi-tenant residential, co-ops, and commercial buildings that want enterprise-grade hardware and a smooth, fairly priced install.

Vertex has been securing NYC buildings for 23 years, and the scale shows – north of 20,000 clients, with 21,000+ cameras installed across the city.

What stands out for buyers is the technology bench: they’re certified partners with Genetec, Brivo, Salto, Axis, Milestone, and Hanwha.

Reviewers consistently praise the front end – knowledgeable staff who explain options without upselling, clean installs, and pricing that beats competitors while holding quality. They also coordinate well with contractors on new builds and retrofits.

The recurring catch is afterward: a noticeable share of reviews flag slow callbacks and patchy support once a system needs servicing. Great install partner; vet the service agreement.

Services

• Access control & keyless entry
• Security cameras & video surveillance
• Intercom systems
• Burglar alarm systems
• Security turnstiles
• Integrated security systems

Pros

• Deep certified partnerships with top-tier platforms (Genetec, Brivo, Salto, Axis)
• 23 years and 20,000+ clients – serious NYC track record and scale
• Strong, knowledgeable pre-sale and install experience, no heavy upselling
• Competitive, fair pricing that reviewers rated well against rivals

Cons

• Post-installation support is the consistent weak spot – missed callbacks and delays cited repeatedly
• Maintenance and issue resolution can lag once a system is live

Score: 4.2/5

7. Abstract Enterprises Security Systems

Best For: Homeowners, landlords, and small businesses across the wider NY metro who want transparent, no-subscription pricing and fast field service.

Abstract takes a different angle from the enterprise players: own your system outright, no monitoring contract, no monthly fees. For budget-minded homeowners and small commercial properties, that’s a real draw, and their published pricing (cameras from $850, cabling from $175/drop) is more upfront than most competitors will put in writing.

They cover a lot of ground too – 9 service areas spanning all five boroughs, Long Island, and the Hudson Valley, with 25+ years behind them. Reviewers single out fast same-day response and clean installs from technicians they name by heart.

The caveat: the field work earns the praise, while management communication and post-sale follow-up draw the recurring complaints. Their breadth (TV mounting, home theatre, AV) also reads more generalist than specialist integrator.

Services

• Security camera installation (4K IP, NVR/DVR, no monthly fees)
• Intercoms & door buzzer install/repair
• Access control (keypad, fob, card, biometric)
• Burglar & fire alarm systems
• Structured cabling (Cat6/6A, fiber)
• TV mounting, home theatre & AV

Pros

• No monthly fees or contracts – you own the system outright
• Transparent, published starting prices (rare in this space)
• Wide coverage across 9 NY metro service areas, 25+ years experience
• Fast same-day response and clean, well-hidden installs praised in reviews

Cons

• Management communication and post-sale follow-up are recurring complaints
• Broad generalist scope (AV, TV mounting) rather than focused enterprise integration

Score: 4.1/5

How To Choose The Best Security Installer NYC Company?

The best security installer NYC has for your property depends on what you’re protecting and how complex the job is.

Here’s what to weigh before signing anything.

Licensing, Insurance & Compliance

This is non-negotiable. An unlicensed install can violate NYC building codes, trigger fines, or force a costly redo – and fire systems carry their own FDNY rules.

Every company here is licensed and insured, but compliance depth varies:

• DGA stands apart with NICET-certified fire design and FDNY approval.
• Abstract also handles fire/code work.

If your building needs serious fire compliance, those two lead.

Scope & System Integration

A single team designing access control, cameras, alarms, and cabling as one platform beats stitching together separate vendors who blame each other when something breaks.

• This is where Highline, DGA, Paragon, and Vertex are strongest – all full-stack integrators.
• NYC Intercom, Eddie’s, and Abstract do excellent work within a narrower lane (intercoms, cameras, smaller installs) but they’re less suited to complex, multi-system builds.

Scale & Property Type

Match the installer to the job:

• Running a multi-site portfolio? Highline, DGA, Vertex, and Paragon handle enterprise scale.
• A single co-op intercom upgrade? NYC Intercom is hard to beat.
• A home or small storefront on a budget? Eddie’s and Abstract are built exactly for that, and overpaying a large integrator for a small job rarely makes sense.

Pricing & Contract Terms

Get multiple quotes and read the fine print.

• Abstract and Eddie’s win on transparency, with published/budget-friendly pricing and no monthly fees.
• DGA sits at the premium end with long contracts (one reviewer flagged a 10-year term).
• Paragon’s emergency pricing surprises some customers.
• Highline is premium and consultative – you’ll get a site survey and a tailored quote.

Post-Install Support

The relationship doesn’t end at handover. Systems need servicing, and a partner who answers is worth a lot.

• Highline, NYC Intercom, Eddie’s, and Paragon all earn strong marks for follow-through.
• This is the clearest weak spot for Vertex and Abstract, where the field work impresses but ongoing support lags.

The Takeaway:

There’s no single best fit.

• Budget-minded homeowners lean to Eddie’s or Abstract.
• Intercom-heavy buildings to NYC Intercom.
• High-compliance commercial sites to DGA.
• For complex, multi-system commercial properties that need one accountable partner from design to long-term support, Highline is the strongest all-rounder.

Best Security Installer NYC FAQs

How much does it cost to install a security system in NYC?

Installing a security system in NYC typically runs from around $850 for a basic camera setup to several thousand dollars for a fully integrated commercial system with access control, alarms, and cabling. Final cost depends on property size, number of devices, and whether you need ongoing monitoring.

Do you need a license to install security cameras in New York?

Yes – installing security cameras and alarm systems commercially in New York requires a NYS Department of State license, and fire alarm work carries additional FDNY requirements. Always confirm an installer’s license number and insurance before hiring, as unlicensed work can breach building codes and void coverage.

How long does a commercial security system installation take?

A commercial security system installation usually takes one to three days for a standard office or retail space, though larger multi-site or integrated builds can run one to two weeks. Timing depends on system complexity, building access, and any cabling or infrastructure work required.

Is professional security installation better than DIY for a business?

For a business, professional security installation is generally better than DIY because it ensures code compliance, proper camera placement, and systems that integrate and scale correctly. DIY kits suit small homes, but commercial properties need certified work to avoid blind spots, false alarms, and coverage gaps.

Conclusion

Finding the best security installer NYC comes down to matching the company to your property.

Highline is the strongest all-rounder for commercial and multi-system buildings that want one team handling design through support. DGA leads on monitoring and fire compliance for high-value sites, while Paragon pairs locksmith depth with serious 24/7 emergency coverage.

NYC Intercom is the pick for co-ops and intercom-heavy residential work, and Vertex brings enterprise-grade hardware to larger installs. For smaller budgets, Eddie’s and Abstract both deliver clean, affordable work, with Abstract’s no-monthly-fee model standing out.

Whichever you lean toward, get a few quotes, check the license, and ask about support after install. For complex commercial properties, Highline’s the one we’d start with.
