Apartment Building Intercom Systems

If you own or manage a walk-up, brownstone, co-op or apartment building, the intercom is the one system every tenant uses every day — and the first thing they complain about when it stops working. We install, upgrade and repair apartment intercoms from 2-family homes to large multi-unit buildings.

Abstract Enterprises Security Systems is a New York State licensed low-voltage contractor (License #12000287431) serving Brooklyn, Manhattan, Queens, the Bronx, Staten Island, Nassau and Suffolk on Long Island, and the Hudson Valley — Westchester, Rockland, Orange, Putnam, Dutchess and Ulster. We install and service Akuvox, DoorBird, ButterflyMX, Aiphone, Comelit and 2N, and we'll recommend the one that fits your building and budget — not the one with the biggest margin.

Options

Choosing the Right Intercom for Your Building

📱

Phone / App Intercom

Tenants answer the door on their cell phone with video and open it from anywhere. No in-unit wiring needed.

📺

Video Monitors in Each Unit

A screen in every apartment. Best for buildings with older tenants or where residents prefer a wall unit.

🔌

Retrofit on Existing Wiring

Replace the front panel and keep the wiring to each apartment. The lowest-disruption upgrade.

🔑

Key Fob & Code Entry

Add fobs, PIN codes or phone unlock so tenants and deliveries get in without keys.

🔒

Door Hardware

Electric strikes and maglocks so the intercom actually releases the door.

🛠

Repair & Service

No audio, no buzz-in, dead handsets, broken panels — we diagnose and fix existing systems too.

FAQ

Apartment Intercom Questions

How much does an apartment building intercom system cost?
+

Most apartment intercom installations run $1,200 to $5,000+, depending mainly on the number of units, whether you keep the existing wiring, and whether tenants get in-unit monitors or answer on their phones. You get a written quote after a free site visit.

Can we keep the existing intercom wiring?
+

Often, yes. Many buildings can replace the front-door panel and reuse the wiring to each apartment, which keeps the cost down and avoids opening walls in occupied units.

Can tenants answer the door on their cell phones?
+

Yes. App and cell-dialing intercoms ring tenants' phones, so they can see and talk to visitors and buzz them in from anywhere. Some buildings mix the two: phones for some tenants and in-unit monitors for others.

Is there a monthly fee?
+

It depends on the system. Some cloud intercoms charge a yearly per-building or per-unit subscription; others have no recurring fee at all. We'll show you both side by side before you choose.

Our intercom is dead. Can you fix it instead?
+

Yes. An intercom service call is $250 and covers diagnosing the problem. Small fixes are usually covered by that visit, and if the system needs a bigger repair or replacement, the fee is credited toward the work.

Can you add a door release, maglock or key fobs?
+

Yes. We regularly pair intercoms with electric strikes or maglocks and key fob or code entry so tenants and deliveries get in without a key.
