Control Who Enters Your Building — From Anywhere
Whether you manage an apartment building, a corporate campus, or a single office suite, knowing exactly who enters your facility and when is essential. National Defense Systems designs, installs, and services a full range of access control and intercom solutions across Rockland, Westchester, and Orange Counties, and New York City. Our veteran technicians bring over 30 years of hands-on experience, so whether you need a new system built from the ground up or an upgrade to your existing setup, we deliver a solution tailored to your property.
We specialize in intercom service for apartment buildings and condominiums, handling everything from legacy analog intercoms to modern IP-based video entry systems. Our expertise also extends well beyond residential buildings. We work with commercial facilities, schools, houses of worship, warehouses, and multi-building campuses to implement access solutions that integrate seamlessly with cameras, alarm systems, building automation, and other technologies you already have in place.
With NDS, you get more than just hardware. We help you choose the right credential type for your environment — ID badges, keyfobs, PIN codes, fingerprint readers, or smartphone-based access — and configure the system so you can track who opens which door, at what time, all from a centralized management platform. We also provide digital locks for lockers and cabinets, giving you granular control over every entry point in your facility.
