Reliable Alarm Monitoring in Phoenix with Instant Alerts and Smart Control

In a city like Phoenix—where the sun is hot and the pace is fast—your security system needs to do more than just sound an alarm. ARCO Lock & Security offers professional alarm monitoring service in Phoenix that’s designed for real life. Whether you’re at home, at work, or out of town, we provide 24/7 protection with rapid emergency response and real-time notifications to your mobile device.


From historic bungalows in Encanto to retail shops in Downtown Phoenix and homes in Ahwatukee, we design systems that fit your space and lifestyle. Our monitoring services are powered by Alarm.com and backed by ARCO’s decades of proven service, giving you the tools to respond quickly—and the confidence that help is already on the way.

  • What types of systems do you monitor in Phoenix?

    We provide 24/7 monitoring for security alarms, smoke detectors, motion sensors, water leak detectors, carbon monoxide alerts, and more.


  • Can I get mobile notifications if my alarm is triggered?

    Yes—our systems send instant alerts to your smartphone via the Alarm.com app, and you can manage the system remotely anytime.


  • Is professional monitoring really better than self-monitoring?

    Yes. Self-monitoring relies on you seeing every alert. Professional monitoring ensures someone responds even when you’re unavailable or asleep.


  • Can you monitor my existing system?

    In many cases, yes. We can assess your current equipment and take over monitoring if it’s compatible—or offer affordable upgrade options.

  • What areas around Phoenix do you serve?

    We serve the entire Phoenix metro, including Arcadia, Biltmore, North Phoenix, South Mountain, Maryvale, and beyond.
