Monitored Systems Make The Difference

Monitored home alarm systems provide several extra layers of protection. For example, if a fire starts or an intruder enters when you are asleep, how quickly will you be able to call for help? A professionally monitored fire, carbon monoxide, and burglar alarm system will call help when you cannot.

Get technology on your side to keep you, your family, and your home safe. Watch the video footage below from one of Security Alarm’s customers. An intruder breaks into their home, activates the alarm, and is rapidly apprehended.

Already Have A Security System? No Problem!

We can service and monitor most previously installed security systems. If you are unhappy with your current security provider, switch to our services for little or no cost and take advantage of our low monthly monitoring rates and fast, friendly service.

Affordable Pricing Options

We offer a wide range of payment options that will allow you to get the home security system you need. Choose from low/high upfront pricing or a leasing option where you can rent your system from us for a lower upfront cost and a monthly leasing/monitoring fee. Under the leasing option, we provide 100% free servicing if something should happen to break or needs professional attention.
