Security System

Security system installation in NYC means designing, installing, and configuring an integrated set of devices — security cameras, access control, alarms, and intercoms — that protect a property and control who enters it. Lock and Tech USA installs and services security systems for residential and commercial properties across all five boroughs and Northern New Jersey, with installation crews dispatched within a 75-mile radius of midtown Manhattan.

The right system depends on the property type, the level of risk, the building’s existing infrastructure, and NYC code requirements. A studio apartment in Brooklyn needs a different setup than a 30-unit walk-up in Manhattan or a retail storefront in Queens.

This page explains what a security system includes, the main types we install, the differences between residential and commercial setups, NYC permitting and compliance, and what drives installation cost.

What Is a Security System?

A security system is an integrated network of devices that monitors a property, detects unauthorized activity, controls access, and alerts the owner or a monitoring service when something is wrong.

A complete system typically combines five layers:

• Surveillance cameras record video of the property and store footage on an NVR or in the cloud.
• Access control determines who can open which doors, using key cards, fobs, codes, mobile credentials, or biometrics.
• Intrusion alarms detect break-ins through door, window, glass-break, and motion sensors.
• Intercoms verify visitors before granting them entry to the building.
• Monitoring connects the alarm system to a central station that receives signals when a sensor triggers.

Standalone devices — a single doorbell camera or a pair of motion sensors — are not a security system. A security system is the integration: every device feeds into one platform, every event is logged, and every entry point is covered.

Types of Security Systems We Install in NYC

Lock and Tech USA installs six core categories of security systems, each addressing a different protection need. The right combination depends on property type, layout, and risk profile.

Security Camera and CCTV Systems

Camera systems use IP or analog cameras connected to an NVR or DVR for continuous recording, with optional remote viewing through a mobile app. Indoor and outdoor cameras, dome and bullet models, fixed and PTZ units, and high-resolution systems with night vision and motion-triggered recording are all supported configurations.

Access Control Systems

Access control replaces or supplements physical keys with electronic credentials. Common configurations include key-card readers, key-fob systems, PIN keypads, mobile-credential apps, and biometric readers. Each credential is logged, can be revoked instantly, and can be restricted to specific doors and time windows.

Burglar and Intrusion Alarm Systems

Alarm systems detect forced entry through door and window contacts, glass-break sensors, and indoor motion detectors. When triggered, they sound a local siren and send a signal to a central monitoring station that contacts the owner and dispatches authorities.

Intercom Systems

Intercoms verify visitors at the entrance before granting access. The most common setups are audio intercoms, video intercoms, IP intercoms with mobile-app integration, and multi-tenant intercom systems that serve apartment buildings with directory boards and individual unit stations.

Biometric Access Control

Biometric systems use fingerprint, facial recognition, or palm-vein readers in place of cards or codes. They are typically used for high-security areas — server rooms, executive offices, medical practices, and laboratories — where credential sharing must be impossible.

Integrated Security Systems

An integrated system combines cameras, access control, alarms, and intercoms into a single platform. One credential controls all doors, one mobile app shows all camera feeds, and one alarm event can trigger automatic camera recording and a text alert. Integration is the standard for any property with more than a handful of doors and devices.

Residential vs. Commercial Security Systems

Residential and commercial security systems differ in scale, monitoring requirements, code obligations, and integration needs.

Residential systems are designed for apartments, brownstones, condos, and single-family homes. They typically include two to six cameras, a door/window alarm panel, a video doorbell or intercom, and a smart lock or basic access control on the main entry. Co-op and condo boards usually require approval before installation begins.

Commercial systems scale to dozens or hundreds of devices across multiple entry points, with credential management for staff, time-and-attendance integration, audit logs for compliance, and tighter integration with building infrastructure. Permitting and code compliance are stricter, and many installations require coordination with property management and building engineers.

Multi-tenant residential sits between the two: a single installation has to manage hundreds of credentials across hundreds of units, comply with NYC intercom and access regulations, and integrate with package rooms, garage doors, and lobby surveillance.

NYC Code Compliance and Permits for Security Systems

Security system installation in NYC is subject to building codes, fire codes, and building-specific rules that affect what you can install and how the work has to be done.

DOB permits may be required when installation involves new low-voltage wiring through walls, structural penetrations, or significant electrical work in commercial buildings. Lock and Tech USA handles permit filing when the scope of work requires it.

Co-op and condo board approval is almost always required for residential installations. Boards typically need to approve any device mounted in common areas, any wiring run through shared walls, and any modification to lobby intercoms.

FDNY oversight applies to fire alarm systems and to security systems that interface with fire panels or life-safety equipment. Fire alarm installation is licensed separately and is not interchangeable with burglar alarm work.

Multi-tenant intercom rules apply to apartment buildings: NYC has specific requirements about tenant access, replacement timelines, and accessibility that affect how intercoms can be replaced or upgraded.

Camera placement is restricted by privacy expectations. Cameras cannot record into a neighbor’s window, into a unit you don’t own, or into spaces with a reasonable expectation of privacy. Placement is reviewed during the on-site walkthrough.

Security System Cost in NYC

Security system cost in NYC depends on five factors: number of devices, property size and layout, equipment grade, integration complexity, and labor.

Number of devices is the largest variable. A small residential system with three cameras and a basic alarm panel costs a fraction of a multi-tenant building wired with a 16-camera CCTV system, full access control on every door, and a video intercom on the front entrance.

Property size and layout affect labor hours and cabling runs. A long brownstone with a finished basement requires more cable, more drilling, and more conduit than a single-floor office of the same square footage.

Equipment grade sets the floor for cost. Consumer-grade cameras and panels are inexpensive but rarely used in commercial installations; professional-grade equipment from brands such as Hikvision, Honeywell, Brivo, ButterflyMX, Akuvox, and Aiphone costs more but lasts longer and integrates cleanly.

Integration complexity raises cost when a system has to communicate with existing building systems — fire panels, elevator controls, access-management software, time-and-attendance — or when multiple sites are tied into a single dashboard.

Labor in NYC reflects the realities of working in occupied buildings: protecting finishes, scheduling around tenants and staff, coordinating with building management, and complying with permit and inspection requirements.

Lock and Tech USA provides a free on-site assessment and a written quote that breaks out equipment, labor, permits, and any monitoring fees as separate line items. A partial deposit is collected before work begins; the balance is due after the job is completed and the system has been tested.
