Bill and Joe were absolutely terrific. They designed and installed a state-of-the-art video surveillance and intrusion system, seamlessly integrating it with the existing builder-installed wiring and camera rough-ins. The end result is clean, powerful, and reliable. I'm especially impressed with the Alarm.com monitoring and video capabilities — intuitive, responsive, and packed with smart features. The entire process was smooth, professional, and exceeded expectations. Extremely happy with the system. Highly recommend Alpha Alarm without hesitation.

We hired Loren and his team at Alpha Alarm to set up a number of temporary camera solutions and a new outdoor entertainment system. If you're looking for a team you can trust and count on, Loren at Alpha Alarm is your guy! Great group of individuals. On time, on budget, and on point! He's the kind of guy you can literally leave alone in your home and know it will be safe, secure and treated with respect. They're responsive. Fair. Talented. Can't wait to crank up my new system for the Halloween Bash! Thanks, Loren. Appreciate it and you very much! Great job! — Jim Mercurio, JCM EVENTS MANAGEMENT & CONSULTING, LLC.
We just purchased a new home and we're looking for a reliable alarm company. Alpha took care of us for getting our alarm installed and cameras for our home. The camera quality is amazing and the app is easy to use on your phone. It's also great to be able to arm and disarm my alarm from anywhere! Dustin was our technician/installer. He had a great personality and knew what he was doing. Everything was very smooth and I'm very happy with our purchase! Definitely recommend!
Best fire alarm company that I have worked with in years!! They know exactly what they're doing with no issues whatsoever. I would recommend them for any type of fire alarm system that you could want.
