Frequently Asked Questions

What level of control do I have with Sonitrol's commercial security system?

Our systems incorporate multiple safety zones and automation features. You’ll have complete access control over every section of your property. We pair the latest in sensor technology with digital locks and smart systems.

Activate or deactivate the security to one or all zones as necessary remotely via your smartphone. It’s an uncomfortable reality today, but one disgruntled client or terrorist can wreak havoc. Being able to lock down your offices and call for help remotely protects your employees and clients.

Sometimes the threat is from inside. Our systems will photograph whoever deactivates a panel manually so there’s always a record of who shut the security off.

You’ll receive instant alerts via the same device outside of office hours whenever someone breaks a sensor. Our fast response team will respond to any emergency calls.

Do you provide maintenance and inspection services?

Our team of 40 highly trained technicians working across Connecticut will deal promptly with client installations, issues, and maintenance. We have a higher technician to client ratio than most security companies because our clients deserve the best.

As for inspections, ensuring that your fire, flood, carbon monoxide, and security systems are in working order is critical for employee safety. You can rely on our team to conduct thorough, regular inspections that will ensure everything is in tip-top shape.

How do installations work?

Call us to get a quote over the phone on your custom system. To make sure we stay on the same page, we’ll send one of our highly qualified security technicians out to your business to evaluate your property. They’ll look for potential gaps, identify blind spots, and recommend security measures for you to take.

We don’t believe in a one-size-fits-all solution. Your business is unique and deserves treatment as such. Our team works with you to find the optimal blend of surveillance and security measures.

What are some of the customization options available on your security system?

You may further customize the system by:

  • Recording keycard access of entrances and exits to the building
  • Integrating the fire alarm, surveillance, and access control systems
  • Choosing your preferred method of detection from magnetic contacts, photoelectric beams, motion or glass break detectors, and pressure or shock sensors
  • Installing time delays for entry and exit
  • Automatically activating the security and switching off the lights
