RESIDENTIAL AND MULTI-TENANT SECURITY SYSTEMS NYC
Apartment Building Security Systems in New York City
Connextivity designs apartment building security systems and multi-unit access control for co-ops, condos, and rental properties across New York City.
Residential buildings have a security problem that offices don't: the people you're securing against are often people who used to belong here. A tenant moves out in March and their fob still opens the lobby in September. A super leaves and nobody knows how many keys went with them.
Credentials, intercom directories, and camera coverage all get designed around turnover, because in NYC turnover is the constant.
What does an apartment building security system include?
Apartment building security systems cover the lobby entrance, common areas, parking, and the credentials residents carry. In NYC the recurring problem is turnover: every move-out leaves a working key fob somewhere. Connextivity designs multi-unit access control and intercom systems around that reality, then commissions them.
Multi-Unit Access Control and Where It Breaks
Package theft is the complaint that reaches the board. Tailgating at the lobby door is the cause.
Most residential breaches aren't a broken lock. Someone holds the door for a person carrying a box, a resident buzzes in whoever says "delivery," or a fob that should have been deactivated eighteen months ago still works. Multi-unit access control fails at the human layer far more often than the technical one, which is why the fix is usually a combination of credential hygiene, intercom verification, and a camera that can actually identify a face at the door.
Connextivity designs integrated security systems that give property managers greater visibility and control across their buildings while helping residents feel safer in their homes.
Our residential security solutions help:
• Prevent unauthorized entry into residential buildings
• Monitor common areas such as entrances, hallways, and parking garages
• Improve tenant safety and confidence
• Provide clear video evidence for incidents and investigations
• Simplify building access for residents, visitors, and staff
Each system is tailored to the size, layout, and security requirements of your property.
Effective residential security is not just about cameras at the front door. It’s about creating a connected system that protects residents while supporting the day-to-day operations of property managers. Connextivity designs integrated residential security ecosystems that include:
Advanced Video Surveillance
High-definition cameras monitor entrances, hallways, elevators, parking areas, and building perimeters, providing property managers with clear visibility and recorded evidence when incidents occur. AI-powered video analytics can help identify suspicious activity and detect unusual events in real time.
Secure Access Control
Control who enters the building with modern credential systems such as key fobs, access cards, or mobile credentials. Access control systems allow property managers to grant, modify, or revoke entry permissions instantly.
Smart Intercom & Visitor Entry Systems
Video intercom systems allow residents to visually verify visitors and unlock doors remotely using their mobile devices. Modern intercom technology can combine live video, two-way audio, and smart call routing to improve both security and convenience.
Integrated Security Management
Bring video surveillance, access control, and intercom systems together into a single management platform that provides real-time visibility across your property.
Security Solutions for Residential Properties
Protect your residents and building assets with integrated security technologies designed for multi-tenant environments.
Remote Management for Property Owners and Managers
Managing security across a residential building or multiple properties requires real-time visibility and control.
Connextivity’s integrated security platforms allow property managers to monitor and manage building security from anywhere using a centralized dashboard.
For example, managers can:
• View live video from building entrances and common areas
• Review recorded footage during incident investigations
• Grant or revoke resident access credentials instantly
• Monitor visitor entry events and access logs
• Manage security across multiple buildings from a single platform
This integrated approach helps property managers maintain security while reducing operational complexity.
Choosing the Right Surveillance System for Residential Buildings
Residential properties require surveillance systems designed specifically for shared living environments.
Different areas within a building require different types of cameras.
For example:
• Dome cameras are commonly used in hallways, lobbies, and elevators because they provide discreet coverage and wide viewing angles.
• Outdoor cameras are ideal for entrances, parking areas, and building perimeters.
• Panoramic cameras can monitor large common spaces with minimal blind spots.
Connextivity designs camera systems that consider:
• Building layout and tenant privacy
• Lighting conditions and blind spots
• High-traffic areas such as entrances and elevators
• Outdoor coverage for parking areas and building perimeters
Our systems deliver clear visibility while maintaining a secure and comfortable environment for residents.
Apartment Building Access Control Credentials
Most NYC buildings are still running 125kHz proximity fobs, which clone with a device that costs about thirty dollars. Moving to an encrypted credential is usually the single highest-value change in a residential retrofit, and it doesn't always require new door hardware.
Mobile credentials solve turnover differently. There's no physical fob to recover, and access ends when you end it. The tradeoff is that every resident needs a smartphone and a working app, which in a building with a wide age range is a real consideration rather than a footnote.
These systems allow property managers to control access to building entrances, parking areas, elevators, and shared amenities while maintaining detailed entry logs for security and accountability.
When integrated with video surveillance, access events can be verified with corresponding video footage, providing a complete view of building activity.

Start With the Credential List
The fastest way to find out where a building stands is to pull the active credential list and compare it against the current rent roll. The gap between those two numbers is the security problem, and it's usually larger than anyone expects.
