Complete Door Buzzer & Entry Access Solutions for NYC Properties


A malfunctioning front door entry system puts your entire building at risk and frustrates tenants. Whether you operate a pre-war residential walk-up, a luxury multi-family brownstone, or a high-traffic commercial building, modern electronic door release systems provide seamless access control and verifiable security.

Core Entry Solutions

Video Intercom Retrofits: Replace buzzing, static-filled audio handsets with high-resolution video panels that let residents see and speak with delivery drivers and guests before buzzing them in.

Electric Strike Door Releases: Install commercial-grade electronic strikes designed for wood, hollow metal, and aluminum storefront doors to deliver instant unlock release commands from buzzers or mobile phones.

Magnetic Lock (Maglock) Systems: Heavy-duty fail-safe holding force ideal for glass lobby doors, office entrances, and interior secure partitions.

Smart Mobile-App Entry: Enable tenants and property managers to unlock front gates and lobby doors remotely from any smartphone, issue digital guest passes, and review time-stamped visual entry logs.

Retrofitting Pre-War NYC Buildings: No Rewiring Required


Installing a modern video entry system does not require knocking down hallway walls or pulling thousands of feet of new cabling.
In older NYC apartment buildings, existing low-voltage copper infrastructure can be converted using specialized multi-wire IP retrofit hardware:

Zero Wall Demolition: The original exterior brass plate is swapped for an all-weather stainless steel touchscreen or push-button panel using the existing backbox.

Repurposed Copper Wiring: Smart signal converters push crystal-clear HD video and crisp two-way audio through the building's current copper lines.

Massive Cost Savings: Avoid extensive conduit installation, wall patching, repainting, and tenant disruption—cutting installation costs significantly compared to full rewiring 
​

Choosing the Right Hardware: Electric Strikes vs. Magnetic Locks


​Selecting the appropriate electronic lock depends directly on door construction, traffic volume, and local building egress requirements.


Electric Strikes (Fail-Secure Standard)

Application: Metal, wood, and standard exterior apartment entry doors.

Operation: Replaces the standard mechanical door frame strike plate.

Security Function: Fail-secure configuration ensures the door remains locked from the outside during a power outage, while interior mechanical door handles always permit free exit.

Magnetic Locks (Fail-Safe Standard)

Application: Frameless glass doors, commercial office suites, and modern architectural entrances where frames cannot be cut.

Operation: Uses powerful electromagnetic retention (typically 600 lbs to 1,200 lbs of holding force).
​
Safety & Code Compliance: Must be configured as fail-safe, instantly releasing when power is cut or when connected emergency fire alarm release sensors are triggered.

NYC Intercom Compliance & Building Code Standards


Installing access hardware in New York City requires strict adherence to local residential and municipal regulations:

NYC Multiple Dwelling Law (MDL § 50-a): Residential buildings with eight or more units must maintain an active, functioning two-way voice communication intercom linked directly to the main building entrance.

Self-Closing & Self-Locking Doors: Exterior building entry doors must feature heavy-duty commercial hydraulic door closers to prevent doors from resting ajar or latching improperly.

ADA Mounting Height Standards: Exterior keypad and camera panels must be mounted at accessible heights with clear audible and visual feedback indicators to accommodate all residents and visitors.

Fire Code Safety Releases: All electromagnetic locking systems must be integrated with approved request-to-exit (REX) motion sensors, pneumatic emergency push buttons, and fire alarm relays to ensure immediate egress.

Frequently Asked Questions (FAQ)

How much does door buzzer system installation cost in NYC?

​Pricing depends on the number of apartment units, the type of locking mechanism needed, and whether the building requires basic audio-only repair or an IP video upgrade. Simple electric strike replacements start at entry-level hardware rates, while complete multi-family video retrofits are custom-quoted based on building scale.

Can old intercom buzzers be connected to smartphones?

Yes. Modern cloud-based IP systems  connect to your building's internet connection, allowing tenants to answer video calls, view live door feeds, and buzz guests in directly via iOS or Android applications.

Will the buzzer still work if the internet or power goes out?

Physical key overrides and battery backup power supplies (UPS) ensure that doors remain accessible and functional during temporary utility interruptions. Electric strike systems maintain standard physical deadbolt functionality at all times.
