Security Systems for Princeton Homes & Businesses
Between the university, the Route 1 tech and pharma corridor, the historic downtown around Nassau Street, and the high end residential, Princeton represents everything that makes security challenging and interesting. Sophisticated access control needs, sensitive research environments, high end homes with serious expectations, we handle all of it.
Certified Protection has been a fixture of New Jersey security for more than four decades. What started in 1983 is now a third generation family owned company where the owners still personally service every account, no call centers, no routed tickets, no one treating your property like a number in a database.
What We Handle in Princeton
Commercial Security Company in Princeton
Princeton commercial work splits between the Route 1 corridor, with its offices, labs, and pharmaceutical and tech tenants, and the retail and restaurants around Nassau Street. Research and corporate spaces usually need card access with a detailed audit trail, cameras on a properly segmented network, and fire alarm systems that match how each suite is actually used.
For Princeton businesses, we design, install, and service:
- Intrusion alarms with door contacts, motion detection, and opening and closing reports, so you know who armed and disarmed the building. Security alarm systems.
- Fire alarm installation, inspection, and monitoring, including the annual testing your insurer and fire official expect. Commercial fire alarms.
- Video surveillance for entrances, registers, docks, and parking, with remote viewing. Business camera systems.
- Card access control with individual credentials, schedules, and an audit trail. Access control.
- 24/7 UL Listed central station monitoring for alarm, fire, and supervisory signals. Monitoring.

Why Princeton Chooses a Family Owned Specialist
The national security companies spend most of their budget on marketing, not on servicing accounts. When something goes wrong with your system, a false alarm at 2am, a camera that won't connect, a fire inspector raising a concern, you get a call center, a ticket, and a scheduling window three weeks out.
That's not how we work. When you hire Certified Protection for your Princeton property, the owners personally handle your account. You have direct lines. Response time is measured in hours, not weeks. And the work gets done right the first time because the people doing it have been doing it for decades. That's why our clients in Princeton and across New Jersey have been with us for generations.
