Video and audio intercom systems

A dead buzzer is usually the strike or the wiring at the panel, not the handset upstairs. We test the run before quoting, then repair, replace or upgrade — from a two-family buzzer to a video intercom on a hundred-unit building.

Diagnosis first, because the wrong end is expensive

Park Slope and Prospect Heights are full of pre-war buildings with intercoms that have been patched for decades. When the door stops releasing, replacing the apartment handset is the most common way this job gets expensive for nothing. We trace the run — panel, strike, transformer, riser — and replace the part that actually failed.

Audio, video and smartphone entry

We install and service the systems Brooklyn buildings actually run: classic audio buzzer panels, video intercoms with in-unit monitors, and app-based entry such as ButterflyMX and Akuvox that lets tenants buzz a guest in from anywhere. Brands we work with include Aiphone, ButterflyMX, Akuvox, Comelit, DoorKing, Alpha Communications, Lee Dan and TekTone. Mixed-use buildings on Fifth and Seventh Avenues get separate directories, schedules and door releases on one panel.

Brownstones and small buildings too

It is not only big buildings. Vestibule electric strikes on rowhouses in Carroll Gardens, Boerum Hill and Windsor Terrace are one of our most common calls — the outer door release that quit, the buzzer that hums but never clicks. We fix those on the same visit, and we pair them with a keyfob reader when the owner wants to stop handing out keys.

Straight answers

My buzzer doesn't release the door — handset or wiring?

Usually the strike or panel wiring, not the handset. We test the run before quoting so you never pay to replace the wrong end.

Can you repair our existing intercom instead of replacing it?

Usually yes — most failures are the strike, the panel or a wiring run. We diagnose first and quote the actual failed part.

Do you install video intercoms tenants can answer on their phone?

Yes — ButterflyMX, Akuvox and similar app-based systems, from panel to wiring to tenant onboarding.
