Lock & Tech USA
Since 1989, 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.
No matter how visitors reach your door, we build the intercom around it
- Front entrances, side doors, and delivery entrances
- Single-tenant offices or multi-tenant buildings
- Audio, video, IP, wireless, or app-based stations
- Staff answering from a desk station or their phone
- One door or several entrances on one system
- New wiring or a wireless setup where cabling is hard
- A new install or an upgrade to an outdated intercom
- Standalone entry or full integration with access control and cameras
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.
Why Businesses Need an Intercom
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:
- Screening visitors, couriers, and deliveries before opening the door
- Letting staff admit people remotely without walking to the entrance
- Managing a locked front door during business hours
- Controlling entry across multiple doors or multiple tenants
- Keeping a record of who was buzzed in and when
Our Intercom Installation Process
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.
Assessment
We review your entrances, the distance to where staff will answer, and whether you need audio, video, or app-based control at each door.
Design
We select the intercom type and stations, and map how the system ties into your door hardware and access control.
Installation
Our licensed technicians mount the entry station and interior units, run wiring or set up the network cleanly, and connect the door release.
Setup & Training
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.
Intercom Types
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 Intercom
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 Intercom
Audio intercoms provide fast two-way voice communication at the door, a simple and reliable option where video isn’t required.
IP / Network Intercom
IP intercoms run over your network, support multiple doors and stations, and scale easily across larger or multi-entrance buildings.
Wireless Intercom
Wireless intercoms suit buildings where running new cable is difficult, providing entry communication without a full wiring project.
Mobile / App-Based Intercom
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.
Integration with Access Control and Cameras
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.
Industries We Serve
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.
Frequently Asked Questions
What’s the difference between an audio and video intercom?
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.
Can staff answer the intercom from their phones?
Yes. With an app-based intercom, door calls go to your staff’s phones, so they can see, speak with, and admit visitors from anywhere — whether they’re at their desk or off-site.
Can the intercom unlock the door and connect to access control?
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.
Can one intercom system cover multiple doors?
Yes. IP and network intercoms support multiple entry stations and interior units, so a single system can manage several doors across one building or multiple entrances.
Is Lock & Tech USA licensed?
Yes. Lock & Tech USA is licensed, and installations are carried out by licensed technicians.
What warranty comes with an intercom installation?
Installations carry a 90-day warranty on mechanical components and a 12-month warranty on electrical components. Repair work is not covered under warranty.
