Happy Clients
Douglas Security System, Inc. (DSS) is an intercom and video surveillance company that serves commercial and residential properties, including property management companies, multi-family housing, and single-family homes. We’re headquartered at 1541 E 46th Street in Brooklyn, New York, and we have over 35 years of experience in the security field.
Intercoms are the heart of what we do. We also handle cameras, access control, locks, and networking, so our customers have one team they can trust with the whole front door. We provide quality services and solutions tailored to our customers’ needs throughout all five boroughs (Manhattan, Brooklyn, Queens, the Bronx, and Staten Island), Long Island, and the tri-state area. DSS is made up of five tightly integrated divisions:
What sets DSS apart is the way we combine three things: professional-grade equipment, affordable prices, and customer service that continues after the job is done. We’re a local Brooklyn company, so when you call, you talk to people who know New York buildings and know your system.
We believe in fixing what can be fixed. If a repair makes sense, we’ll tell you. If an upgrade will save you money over time, we’ll show you the numbers. Every job starts with a free quote, and you can call us anytime about pricing options and payment methods.
We’re based in Brooklyn and work across all five boroughs: Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. We also serve Long Island and the rest of the tri-state area.
Our customers include property managers, co-op and condo boards, landlords, store owners, and homeowners. We work on pre-war walk-ups, brownstones, large apartment complexes, office buildings, storefronts, and private houses. See our full list of intercom and security services.
We install and repair systems from Comelit, Aiphone (GT and IP series), DNAKE, Akuvox, ButterflyMX, DoorKing, Linear, Leedan, Elvox, 2Easy, and Invid. Because we work with many brands, we can recommend the system that fits your building instead of pushing one product line.

Douglas Security System (DSS) has worked on intercom and security systems in New York for over 35 years. What started as intercom repair for apartment buildings grew into a full security company that installs and services intercoms, security cameras, access control, locks, and the cabling that connects them. Our office is at 1541 E 46th Street in Brooklyn, and our technicians work across Brooklyn, Manhattan, Queens, the Bronx, Staten Island, and Long Island.
In that time, building technology has changed a lot. Many of the buildings we serve went from basic audio buzzers to video panels, and now to systems tenants answer on their phones. We’ve installed and repaired all of them, which is why we can usually tell quickly whether an older system is worth fixing or ready to be replaced.
We believe a good security company should save you money, not sell you the most expensive option. That’s why we work a certain way:
Our customers include property managers, landlords, co-op and condo boards, supers, homeowners, and business owners. For buildings, we coordinate with managing agents and supers, work around residents’ schedules, and keep the entrance working for as much of the job as possible. For homeowners, we explain the options in plain language and install systems that are easy to use every day. For businesses, we install entry systems that let staff see visitors before opening the door.
We install and service every generation of building entry system. That includes older 5-, 4-, and 3-wire audio intercoms, video intercoms with monitors in each apartment, and app-based systems that let tenants answer the door and open it from their phones. Our Comelit systems are no monthly fee intercom systems, and cloud-based systems like the DNAKE S617 add remote management for buildings that want it. Whatever you have now, we can help you keep it running or move to something better.
A new system is only useful if people know how to use it. After every installation, we walk the super, manager, owner, or staff through the system: how to add and remove residents, change codes, set up the app, and what to do if something stops working. We leave the building with a clear point of contact, and we’re available afterward for changes, added users, extra entrances, and repairs. For buildings with several properties, we keep equipment consistent so the same training and parts work everywhere.
Call (212) 262-2820 to get started.
Reliable means the system works when a tenant is standing at the door in the rain. It also means the company that installed it answers the phone. That’s the standard we hold ourselves to on every job.
Our technicians are fully trained and certified in intercoms, video surveillance, and access control. We install professional-grade equipment from Comelit, Aiphone, DNAKE, Akuvox, ButterflyMX, and DoorKing, and we stand behind it. On Comelit video intercom installs, you get a 3-year guarantee on Comelit material and a 1-year guarantee on service and labor.
Yale NexTouch keyless electronic door locks combine a modern look with durability that is perfect for your multi-family or mixed-use property, small business, office, retail space, restroom, or other commercial building application. Tenants and staff use a PIN code instead of a key, and you can change codes any time without calling a locksmith.
We install NexTouch locks on their own or together with your intercom and access control system, so the whole entrance works as one. Ask us about our security lock and access control services.
