Intercom installation in Manhattan, for co-ops, condos and offices.
Video lobby panels, 2-wire upgrades on existing riser wire, and IP intercoms for Manhattan's pre-war co-ops, walk-ups, condo towers and office lobbies. The old wire is tested before anyone plans on reusing it, and every door release is tested before we leave.

Highlights show where each building type is common, not the only places we work. We install intercoms in every Manhattan neighborhood.
In Manhattan, the building decides how the intercom goes in.
Boards and managing agents, pre-war risers, two-door entrances, historic districts, staffed lobbies and office towers.
Board and managing agent paperwork
Co-op and condo boards usually ask for an alteration agreement, a certificate of insurance and a written scope before work starts. We provide the certificate, with the building named as additional insured when the board asks, and a scope that lists every door and every apartment visit.
Pre-war riser wire, tested first
Many pre-war buildings already have intercom wire running up the risers to every line of apartments. We test it before we plan on it. Where it passes, a 2-wire video system can run on it; a segment that fails gets replaced.
Two doors at the entrance
Many Manhattan entrances have an outer street door and an inner lobby door. Each gets its own lock hardware and its own relay, so the panel can release them in order or one at a time. People inside can always get out.
Historic districts
From the Upper West Side to Greenwich Village, SoHo and Hamilton Heights, much of Manhattan sits in historic districts. In a landmarked building or historic district, exterior work may still need Landmarks Preservation Commission approval.
Doorman desks and service doors
In a staffed building the lobby panel can ring the desk first, and the desk station can call any apartment. A separate service entrance gets its own station, so the porter or the super can answer deliveries there.
Commercial lobbies and suites
Office buildings in Midtown and the Financial District need a tenant directory in the lobby and suite stations that ring reception, or desk phones over SIP. After hours, calls can go to building security.
From a walk-up to a tower, the lobby panel changes.
Manhattan runs from five-story walk-ups to towers with hundreds of apartments. The directory on the panel has to fit the building. Pick one of three examples.
A small building fits every apartment on the panel face. The visitor presses 4C, the call runs up the old buzzer wire to that apartment, and the resident presses Door.
Too many apartments for a row of buttons, so the panel shows a list on a display. The visitor scrolls to 8F or dials its code, and the call goes up the riser to that line.
Hundreds of units need search. The visitor types a name or unit, the call reaches the resident's app or monitor, and a concierge button rings the desk.

Two things shape intercom work in Manhattan more than anywhere else: the entrance rules for apartment buildings and the historic districts.
Under New York Multiple Dwelling Law section 50-a, an apartment building erected or converted after January 1, 1968 with eight or more apartments must have an intercom at the main entrance, along with self-closing, self-locking entrance doors. This is general information, not legal advice. Read the NYC building security compliance guide.
In a landmarked building or historic district, exterior work may still need Landmarks Preservation Commission approval. Manhattan districts include Upper West Side/Central Park West, Upper East Side, Greenwich Village, SoHo-Cast Iron, East Village/Lower East Side, Hamilton Heights/Sugar Hill and the Tribeca districts.

What goes into a Manhattan intercom job.
The building changes the panel and the wiring. The parts list stays the same.
Lobby panel
Video · directoryA video door station with a wide-angle camera, a directory that fits the building (buttons, a scrolling list with a keypad, or a searchable touchscreen), and an IP rating for weather and an IK rating for impact at a street door.
Door release hardware
Strike · maglockAn electric strike in the frame of a wood or steel door, or a magnetic lock on the header of a glass and metal door with an exit sensor. We pick the lock for each door around its use and the building's fire and life safety requirements. A magnetic lock needs a free way out from inside at all times.
Lock power and relays
Low voltageA separate low-voltage power supply for the locks, switched by the intercom relay for a few seconds when someone presses Door. One relay per door, so the outer and inner doors can release on their own. Power work is coordinated with the electrician.
Wiring
2-wire · Cat6The existing riser pair for a 2-wire video system once it tests good, or Cat6 with PoE for IP stations, each run within the 100 m channel limit. Every penetration we make through a fire-rated wall or floor is fire-stopped.
Answering
Station · app · deskIn-unit stations or monitors for residents who want them, the phone app for the rest, and a desk station where the lobby is staffed. Calls can follow a schedule: the desk by day, residents directly at night.
Directory and records
ManagedThe managing agent or the super updates names and unit codes from a dashboard, issues temporary codes with start and end times, and sees a log of door events.
From the old panel to a tested system.
The wire test comes before the plan. The release test comes before we leave.
Site visit and wire test
We walk the entrances with the super, open the old panel and test the existing wire before anyone plans on reusing it.
Written scope for the board
Doors, panel, hardware, wiring and apartment visits in writing, with the certificate of insurance the board or managing agent asks for.
Installation
Lobby work and apartment visits booked by floor, inside the hours the building allows. Every door release is tested at every door.
Handover
The directory loaded, residents set up on the app or a station, and the super shown how to add and remove names.
What our clients say.
Word for word from our Google reviews, from homeowners, building staff and business owners.
"Really happy with Seneca Security. Their team clearly knows home security inside and out. They walked me through the options and put together a custom setup that fit exactly what I needed, instead of pushing a one-size-fits-all package. The crew showed up right on time, got the whole system installed in a single day, and the install was clean, with tidy wiring and no mess left behind. Highly recommend them to anyone looking for a solution built around their home."
"They mapped all my existing wiring and helped me come up with a plan as to move wiring to accommodate my televisions and set up WiFi to extend throughout my condo so there were no gaps in coverage. ... They also cleaned up the wiring in the closet so that it looks clean and organized. I can’t say enough wonderful things about Alexander and Joseph."
"They installed a 14 camera system in my store & an electronic door lock. Very clean job, very professional! Took the time to show me how to fully work the system."
"Seneca came to fix & replace cameras in the building I work at. They were able to fix the problem within 1 day. Great experience with them."
Manhattan intercoms, answered.
How much does intercom installation cost in Manhattan?
It depends on the building. The price comes from the number of entrances and apartments, whether the existing riser wire tests good enough to reuse, what residents answer on, the door hardware and the directory type. Board paperwork and apartment visits are part of the plan too. We give a written quote after a site visit.
Can you replace the intercom in an older Manhattan apartment building without rewiring every apartment?
Often, yes. Many older buildings already have intercom wire in the risers. We test it first; where it passes, a 2-wire video system can run on the same wire, and a segment that fails gets replaced. A cloud lobby panel that calls residents' phones needs no wiring to the apartments at all.
Do you install commercial intercom systems in Manhattan?
Yes. Office lobbies get a tenant directory and video door stations, and suites get stations that ring reception, or desk phones over SIP on the office network. Calls can move to a backup group or to building security after hours, and an IP station can include a card reader for staff.
Does a Manhattan apartment building need an intercom?
Under New York Multiple Dwelling Law section 50-a, an apartment building erected or converted after January 1, 1968 with eight or more apartments must have an intercom at the main entrance, along with self-closing, self-locking entrance doors. This is general information, not legal advice. Our NYC building security compliance guide covers it in more detail.
Do you work with co-op boards and managing agents?
Yes. We provide a written scope and the certificate of insurance boards ask for, with the building named as additional insured on request, and we schedule lobby work and apartment visits through the managing agent and the super.
Do you install video doorbells in Manhattan?
Yes, at townhouse, brownstone and private entrances. In a masonry building a wired video door station is usually more reliable than a Wi-Fi doorbell, because brick and stone weaken the signal from the router. Either one needs steady power, from a doorbell transformer or PoE.
Do you repair intercoms in Manhattan?
Yes. We repair dead lobby panels, one-way audio, doors that will not release and worn handsets, in apartment buildings and offices. If a system is past repair, we quote the replacement in writing.
Can residents answer the lobby door on their phones?
Yes. Most current systems can ring a phone app, and some lobby panels call residents' phones directly over the internet or a cellular connection. Residents who prefer a station on the wall can keep one on the same system.
Do you work in landmarked buildings?
Yes. In a landmarked building or historic district, exterior work may still need Landmarks Preservation Commission approval. A new panel inside the vestibule, or in the opening of the old one, can keep exterior work small; we look at both options on the site visit.
What areas of Manhattan do you serve?
All of Manhattan, from Inwood and Washington Heights to the Financial District and Battery Park City. We also work in Brooklyn, Queens, the Bronx, Staten Island, Long Island and New Jersey, and on selected jobs in Connecticut.
