5 Best Security Systems in New York (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

A jewelry store owner, a nonprofit office, and a Bronx warehouse do not need the same security system, and in New York that decision usually comes down to who actually installs and monitors it well. The security systems companies on this page have logged over 800 Google reviews between them, and the ratings run from 4.7 up to a perfect 5.0.

Short answer: DGA Security has the deepest track record here, 4.8 stars across 302 reviews, and specializes in commercial intrusion alarms, access control, and fire systems with 24/7 monitoring. For residential or small-business intercom and camera work, NYC Intercom & Security Solutions (4.9, 225 reviews) comes up often for fast, honest service. Commercial system installs typically run into the thousands depending on cameras, access points, and monitoring plan.

Watch: 5 Best Security Systems in New York (2026)

How we score

Rating is each company’s live Google average. Review volume measures how many customers actually left a review, ranked against the others on this page. Confidence blends the two, since a perfect score on a small number of reviews carries less weight than a strong score at real volume. Recency checks how recently people are still reviewing them. No business can pay to change any of these numbers.

How much does a security system cost in New York? (2026)

None of the companies on this page publish a fixed price list in the data we reviewed, and cost varies widely by number of cameras, access points, monitoring plan, and whether it’s a residential or commercial install. Reviewers describe everything from a single-office camera add-on to full warehouse setups, so get a site visit and written quote before committing.

Serving all five boroughs

These installers cover Manhattan, Brooklyn, Queens, and the Bronx, with reviewers describing jobs from Midtown offices to Bronx warehouses to Brooklyn therapy suites. If you’re searching for a security system company near me anywhere in the city, the businesses above have documented work across most boroughs.

What to ask before you hire a security systems installer

Is monitoring included, and what’s the monthly cost after installation?
Do you own the equipment after install, or is it leased?
What happens if the internet or power goes out?
Can the system integrate with existing building access cards or intercoms?
What’s the response time if a technician needs to come back?
Is there a contract, and what’s the cancellation policy?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.

How did you choose these security companies?

We pulled real Google Business Profile data for security systems installers serving New York, then ranked by rating, review volume, and how recently customers are still reviewing them.

How often is this list updated?

We last verified this data in August 2026 and refresh it periodically as ratings and review counts change.

Do I need a permit to install a security system in an NYC apartment?

It depends on your building. Co-ops and condos often require board approval for camera or intercom changes, so check with building management before scheduling.

What’s the difference between a monitored and unmonitored system?

A monitored system alerts a monitoring center that can dispatch police or fire services. An unmonitored system sends alerts to your phone but relies on you to respond.

The bottom line

DGA Security is the safest default for a business that wants integrated security and fire compliance under one vendor. For a straightforward residential or small-business camera and intercom job, NYC Intercom & Security Solutions has the strongest reviews for communication. Either way, get a site visit and a written quote before signing a monitoring contract.
