Advanced Burglar Alarm Systems

Alltech’s residential burglar systems use state-of-the-art technology to detect unauthorized entry and alert you immediately.

With 24/7 professional monitoring, our central station responds to any alarm event within seconds—ensuring that help is on the way when you need it most.

Residential Fire Protection

Fire emergencies can happen when you least expect them—and seconds matter. Our residential fire alarm systems provide early detection of smoke, heat, and carbon monoxide, helping to protect your home and loved ones from devastating loss.

Every system we install is monitored around the clock, ensuring that first responders are immediately notified in the event of an emergency. From single smoke detectors to full-home integrated systems, we deliver protection that never sleeps.

Testimonials
"I can't recommend them enough..."

"I’ve been very happy with my service.."

“Alltech has been my alarm company since I bought my house 13 years ago.  My various family members have accidentally set off the alarm upon entering the house several times—so we have tested the system periodically—and Alltech was very quick to respond!  In addition to having an effective security system, they have been very responsive to my every need including some random requests over the years—for alarm certificates, amending access codes and call lists, and answering questions about the macros built into my system (pool / door alarm) that I had no recollection about.  I’ve been very happy with my service and would highly recommend Alltech to others!”
