How We Work

Site Assessment

We visit your property in Yonkers, Mount Kisco, or elsewhere in the county to understand layout, entry points, and building code requirements. No two properties are the same.

Professional Installation

Licensed technicians arrive with tools and materials. We install cleanly, test every sensor and camera, and walk you through all features and alerts.

24/7 Monitoring

Your system connects to our UL-listed central station. Alarms trigger immediate alerts to you and first responders. Peace of mind around the clock.

Ongoing Maintenance

We schedule routine check-ups, replace batteries, and service your system year-round so it stays ready when you need it most.

You'll always know what's happening next—and when.

Frequently Asked Questions

How long does a typical alarm system installation take?

Most residential systems take 2–4 hours. Larger commercial properties in White Plains or Purchase may require a day or two depending on complexity. We'll schedule around your calendar.

Do I need a building permit for a security system installation in Westchester County?

Most alarm and camera systems don't need permits, but fire alarm integration may. We handle all permit research and ensure your system complies with local fire codes and electrical inspections.

Can I monitor my security system from my phone?

Yes. All our systems include mobile app access. View live camera feeds, arm/disarm, and receive instant alerts whether you're in Tarrytown or traveling abroad.

What happens if my alarm goes off during testing?

Tell our team before you test. We set your system to test mode so alerts don't trigger the central station or emergency response. Once installation is complete, live monitoring begins.

Do you service and repair existing systems?

Absolutely. Battery replacement, sensor repair, camera troubleshooting, and annual inspections keep your system running smoothly. Call anytime you suspect a problem.

Are your technicians licensed and insured?

Yes. All technicians hold Westchester County licenses and carry full liability and workers' compensation insurance. You're protected.
