Customized Solutions

We’ll sit down with you and design a customized security solution to meet the needs of your business.

Multiple System Integrations

We can integrate a business alarm system with a fire alarm and other security devices.

Lowered Insurance Premiums

Your insurance company may offer you a discounted rate or lower premiums for having a security system.

Gain Peace of Mind

Rest assured that your business is protected even when you’re not there. Our security systems provide 24/7 monitoring and protection.

Monitored Systems Make The Difference

Make sure you get a monitored security system. If a fire starts or an intruder enters when you aren’t there, can you call for help yourself? A professionally monitored fire, carbon monoxide, and burglar alarm system call for help when you cannot.

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

Already Have A Security System? No Problem!

Have an existing system but are locked into a long contract with ADT or another security provider? We may be able to buy out part of your contract!

We specialize in servicing and monitoring previously installed commercial security systems. If you’re unhappy with your current provider, make the switch to Security Alarm for little to no cost. You’ll be able to take advantage of our low monthly monitoring rates and prompt, friendly service.
