Best Alarm Company in Greenwich CT

We are a local company — not a franchise. You own your equipment outright (no leasing), there are no long-term contracts, and your footage stays on a local NVR instead of a corporate cloud. Plus, our technician is 15 minutes away, not in another state.

Most residential alarm installations in Greenwich are completed within 1 business day. We offer same-week scheduling and can often accommodate urgent requests within 48 hours.

Greenwich requires an alarm permit for systems connected to police dispatch. We handle the permit application process as part of our installation service so you don't have to worry about paperwork.

Yes. We regularly upgrade older wired alarm panels to modern smart systems while reusing existing sensor wiring. This saves you money on new sensors while giving you smartphone control and video verification capabilities.

Yes. Unlike ADT, Vivint, and other national providers that require 3–5 year contracts, we sell and install your alarm system outright. You own the equipment from day one with zero monthly monitoring fees or cancellation penalties. This is one of the most common reasons Greenwich homeowners choose us over national chains.

Wired sensors are more reliable for permanent installs — no batteries to replace, no RF interference, and a more stable connection to the alarm panel. Wireless sensors are better for rentals, retrofits where running new wire isn't practical, or additions to existing systems. For most Greenwich homes, we recommend a hybrid approach: wired sensors on primary entry points and wireless for interior motion detectors or hard-to-reach areas.

Yes. Modern alarm systems integrate with Alexa, Google Assistant, and Apple HomeKit, allowing you to arm or disarm with voice commands. We can also set up automation routines — for example, when you arm the alarm, smart locks automatically engage and lights turn off. If you have a Ring or Alexa-compatible system, your alarm can trigger smart lighting and send alerts through existing Echo devices.
