Call (212) 262-2820. For requests that aren’t urgent, you can also use the form on this page or email douglassystem@yahoo.com. A phone call suits a dead entry panel or a door that will not latch, because we can ask questions right away. The form and email suit quotes and scheduling, and they let you attach pictures of the panel, the apartment unit, and the wiring behind them.

No. Every job starts with a free quote. We inspect your system and give you a clear price before any work starts. The inspection comes first because intercom faults hide behind walls. A dead apartment unit might be a bad unit, a cut wire, or a failed power supply. A price given without looking would be a guess in either direction, so we look first and then put the number in writing.

Include the property address, the type of building, the number of apartments or doors, what isn’t working, and the brand of your system if you know it. Photos of the entry panel help too, and you can send them by email. The name or logo on the panel often tells us the brand. Also say whether one apartment or the whole building is affected, since that points to different causes.

Yes. A technician inspects the wiring, entry panel, apartment units, and door striker, because the final price depends on what we find. Each part can fail independently, and the symptom at the front door often hides the real cause. A buzzer that will not open the door may need a new striker, a power supply, or a repaired wire run, and those jobs cost very different amounts.

Yes. We repair older 5-, 4-, and 3-wire audio systems and brands like Aiphone, Comelit, Elvox, Leedan, and 2Easy. If parts are no longer available, we’ll explain your upgrade options. Wire count matters because it limits what a system can do: fewer conductors mean simpler audio, while video may need different cabling. Comelit video upgrades often work alongside existing apartment units and wiring, so many buildings avoid rewiring.

Yes. Many of our customers are property managers and co-op boards. We give each building its own quote and keep track of each system. Tracking matters when you manage several addresses, because one building may run Comelit, another Aiphone, and a third an unlabeled older panel. Knowing which is which saves time when a resident reports a problem, and it helps when a violation arrives for one specific address.

We serve Brooklyn, Manhattan, Queens, the Bronx, Staten Island, Long Island, and the rest of the tri-state area. The work varies by area. Prewar walk-ups and co-ops with aging wiring are common in Manhattan and Brooklyn. Queens, the Bronx, Staten Island, and Long Island add many private houses and storefronts alongside apartment buildings. Each type calls for a different mix of audio, video, keypad, and camera equipment.

We do both. We repair existing intercoms, cameras, and access control, and we install brand-new video intercom systems, camera systems, keypads, and smart locks. If a repair makes more sense than a new system, we will tell you. A repair usually wins when the fault is one part, such as a power supply or a door release. Replacement makes more sense when parts are discontinued or the system keeps failing.

No. Our Comelit systems are a one-time investment with no monthly payment. Property management software and call-log servers are optional and sold separately. You pay once for the equipment and installation, and the intercom keeps working without a subscription. The optional items mainly suit larger buildings that want a central record of calls. A small walk-up rarely needs them.

Our office is at 1541 E 46th Street, Brooklyn, NY 11234. Intercom repairs and installs happen at your building, since faults must be traced at the entry panel, the apartment units, and the wiring between them. For a quote, you do not need to come to the office. Send the property address and photos of your panel, and the technician inspects on site.

Yes, Douglas Security System is licensed and insured, and our technicians install and repair intercom, camera, and access control systems across NYC and Long Island. Intercom work means opening entry panels, running cable through hallways, and sometimes cutting power to a door that residents rely on. An insured contractor is accountable for that work. We also bring over 35 years of experience in New York to each job.
