Video, audio, IP, and mobile intercoms from Aiphone, Comelit, and Akuvox — installed and integrated with your access control by a licensed team in NYC.
Since 1998, we’ve been securing homes and businesses across NYC and New Jersey with professional security solutions you can trust. Our licensed technicians provide 24/7 emergency service, using only the latest technology and backed by comprehensive warranties on all installations.

Every visitor at your door is a small decision: let them in, or find out who they are first. A business intercom makes that call easy — your staff can see and speak with whoever’s outside and release the door without leaving their desk. Lock & Tech USA installs intercom systems for offices, buildings, and multi-tenant sites across New York City, using equipment from Aiphone, Comelit, and Akuvox.
An intercom works best paired with your access control, so one credential and one app run the front entrance. As part of a complete business security system, it shares a platform with your cameras and alarm too. Our licensed team handles design, installation, and configuration, with a fixed quote before any work begins.
An unlocked door is convenient and risky; a locked door with no way to screen visitors is secure and inconvenient. An intercom solves both — it keeps the door locked while giving staff a fast, clear way to verify and admit anyone who belongs inside.
A business intercom helps in situations like these:

An intercom has to be easy at the door and easy for staff, so we plan placement and wiring around how visitors and employees actually use the entrance.
We review your entrances, the distance to where staff will answer, and whether you need audio, video, or app-based control at each door.
We select the intercom type and stations, and map how the system ties into your door hardware and access control.
Our licensed technicians mount the entry station and interior units, run wiring or set up the network cleanly, and connect the door release.
We configure call routing, mobile access, and door release, then walk your team through answering calls and admitting visitors from a station or their phone.
The right intercom depends on your entrance, your building, and how your staff prefer to answer. We install the following types to fit each setup.
Video intercoms let staff see who’s at the door before opening it — the standard choice for businesses that want to verify visitors by sight, not just voice.
Audio intercoms provide fast two-way voice communication at the door, a simple and reliable option where video isn’t required.
IP intercoms run over your network, support multiple doors and stations, and scale easily across larger or multi-entrance buildings.
Wireless intercoms suit buildings where running new cable is difficult, providing entry communication without a full wiring project.
App-based intercoms send door calls to your staff’s phones, so they can see, speak with, and admit visitors from anywhere — on-site or not.
An intercom is at its best when it’s not working alone. We integrate it with your access control, so the same system that verifies a visitor also releases the door and logs the entry. We also tie it into your business cameras, so door calls line up with footage and you have a full record of who came and went — all managed on one platform instead of separate apps.
Entry management looks different in every setting, and we design each system to match — from the controlled front doors of schools and the staff and delivery entrances of warehouses, to the visitor-heavy lobbies of hospitals and the multi-tenant entries of apartment buildings.
An audio intercom lets staff speak with a visitor before opening the door, while a video intercom also lets them see who’s there. Most businesses choose video so entry decisions are based on both voice and a clear view of the visitor.

Yes. We integrate the intercom with your access control so admitting a visitor releases the door and logs the entry, and with your cameras so calls line up with footage — all on one platform.

Yes. Lock & Tech USA is licensed, and installations are carried out by licensed technicians.
