End-to-End Security Systems for Commercial, Residential & Multi-Tenant Properties Across All Five Boroughs
Physical Security Services in New York City
Connextivity provides physical security services across New York City. Every project starts with a vulnerability assessment and ends with a commissioned system. We work in Manhattan high-rises, Brooklyn waterfront developments in DUMBO, Long Island City commercial corridors, Bronx multi-family housing, and Staten Island industrial facilities. Each borough brings different building stock and different constraints.
Security Services Tailored for NYC Properties
Whether you're managing an office tower in the Financial District, a multi-tenant building in Brooklyn, a warehouse in Long Island City, or a luxury residence on the Upper East Side, the work starts the same way: understanding the property before specifying equipment.
Our vulnerability assessments look at what's already installed and where the real gaps are, then produce engineering-driven recommendations. The consulting is vendor-neutral, which means the assessment doesn't arrive with a predetermined shopping list.
SECURITY ASSESSMENTS
Certified, in-depth security evaluations for residential and commercial properties. We identify vulnerabilities, analyze existing systems, and provide clear, prioritized recommendations. No sales pressure. Just objective guidance to strengthen your property’s protection.
SECURITY CAMERAS
Enterprise-grade IP surveillance systems designed for performance and reliability. From perimeter coverage to high-traffic areas, we deploy smart camera solutions that deliver clear footage, remote access, and long-term scalability.
ACCESS CONTROL
Secure, scalable access control for homes, gated communities, offices, and mixed-use buildings. Manage credentials, monitor entry activity, and control doors remotely with centralized, user-friendly systems built for modern properties.
VIDEO INTERCOMS
Modern video intercom solutions that transform how visitors enter your property. Verify guests with real-time audio and video, grant access remotely, and create a documented, secure entry experience for residential and commercial buildings.
ALARM SYSTEMS
Intelligent intrusion detection systems built for rapid response and reliability. Protect against unauthorized entry with professionally designed alarm solutions that integrate seamlessly with your broader security infrastructure.
SECURITY SYSTEM MAINTENANCE
Proactive service and preventive maintenance to keep your security systems operating at peak performance. We monitor, test, and optimize your infrastructure to reduce downtime, extend system life, and prevent costly failures.
NETWORKING & IT INFRASTRUCTURE
Security-focused network design and structured cabling built specifically for IP-based systems. We create reliable, high-performance backbones that ensure your cameras, access control, and intercoms operate smoothly and securely.
LEGACY SYSTEM UPGRADE
Upgrade outdated analog or fragmented systems into modern, integrated platforms. We modernize your infrastructure strategically, improving performance and security without unnecessary full-system replacements.
The Network Behind Your Security System
Every camera, card reader, and intercom on an IP system is a device on your building's network. When the network isn't designed around them, the problems surface months later. Cameras drop offline overnight and nobody notices until someone needs the footage. Door controllers stop reporting until a switch gets power cycled in a closet nobody has opened in a year.
We design the network alongside the security system. That covers structured cabling, keeping camera traffic segmented away from tenant and office traffic, PoE budgeting that accounts for every device on the switch, firewall configuration, and building-to-building wireless links where running fiber isn't practical.
However, this is also where a lot of inherited systems fail. If your cameras share a flat network with everything else in the building, bandwidth contention is the visible problem and lateral exposure is the one nobody sees.

Solutions for Your Property
Engineered for the Realities of New York City
In a city that hosts Times Square’s New Year’s Eve celebration, the New York City Marathon, and the Macy's Thanksgiving Day Parade, security is not simply about cameras.
Whether you are:
Securing a luxury condominium overlooking the High Line
Managing multi-family access control in a Brooklyn brownstone
Engineering corporate security near Wall Street
