NAPCO Security Systems in Chicago

American Security Manufacturing Since 1969

NAPCO Security Technologies (NASDAQ: NSSC) was founded in 1969 and is headquartered in Amityville, New York. The company is a publicly traded manufacturer of security alarm systems, communication devices, electronic locks, and door hardware. NAPCO’s portfolio includes four primary brands: NAPCO (alarm panels), StarLink (cellular alarm communicators), Alarm Lock (electronic access locks), and Marks USA (commercial door hardware).

NAPCO represents a vertically integrated American manufacturer of security hardware — panels, communicators, locks, and door hardware all produced domestically. This integration means tighter compatibility between products and supply chain stability independent of overseas manufacturing dependencies.

NAPCO Alarm Systems in Our Service Rotation

NAPCO panels guard plenty of Chicago storefronts and small commercial spaces — American-made intrusion gear with a long service history. Like most alarm hardware, the panels outlive the companies that installed them, which is when we get the call.

We take over NAPCO systems: reset locked programming, replace tired keypads and sensors, and reconnect monitoring through providers the owner chooses rather than gets locked into. If the building is also adding cameras or door control, we make the old panel a team player instead of an orphan.
