Residential Security Systems

We take great pride in custom-designing every security system we install. Our top priority is to provide you with a system that adequately protects your home and suits the way you live and work.



Residential Fire Protection

Home fires can start in the blink of an eye.

A residential fire alarm system will give you and your loved ones the precious seconds you need to get to safety.

When the fire alarm system detects extreme heat or smoke, it will sound a loud alert and immediately notify the fire department.

Residential Smartphone Control

Our Remote Safe home automation platform connects your cell phone or tablet to your home security system.

You’ll get complete access and control over your system—no matter where you’re physically located. All you need is your device and an internet connection.

You can remotely perform a wide range of tasks, including turning on the heater, receiving notifications if certain parts of your home are accessed (medicine cabinet, gun safe, etc.), and arming and disarming your security alarm system.



Home Security Cameras

Installing indoor and outdoor cameras will add several extra layers of surveillance and protection for all those living under your roof.

Smart home security systems and motion sensors are more affordable than ever and offer a wide range of technological innovations to reduce false alarms and safeguard your home.

“ We have been customers of Security Alarm for 8 years at our current home. The peace of mind and ease of use are priceless. So much so that we are installing their system with some added features to our new home.

We have always found every employee of this company to be helpful & straight forward.

On the occasions that we have accidentally set off our alarm, it has been less than a minute before the monitoring center are calling to check in.

If you are in the market for a security system, we highly recommend you give Security Alarm the opportunity to explain their system to you. ”
