Video Intercom Installation & Buzzer Replacement in New York City
Still running an old buzzer or audio-only intercom? LM Fire & Security upgrades apartment buildings, co-ops, condos, offices and homes to modern video intercom systems across Brooklyn, Queens, Manhattan, the Bronx, Staten Island, Long Island and Westchester.

Can we reuse your existing wiring?
Often, yes. Running new wire through an occupied building is usually the biggest cost in an intercom upgrade. Before we price your job, we check the existing buzzer wiring. If it’s in good shape, we choose a video intercom system that can run on it, which saves you time, money and disruption to your tenants.
If the old wiring is damaged or can’t support a video system, we’ll tell you up front, run new wiring, and adjust the scope and price before any work starts. No surprises halfway through the job.
The right system for your budget
We aren’t tied to any one manufacturer. We install multiple intercom brands and recommend the system that fits your building, your wiring and your budget, not the one we’re paid to push.
Brands we install include Aiphone, BEC Integrated, Lee Dan, Hikvision and other major intercom manufacturers. We are also a certified ButterflyMX installer. Have one of these systems already and need it repaired, expanded or replaced? We can help.
