Glendale Alarm Monitoring Solutions Built for Real-World Security

When it comes to security, fast response is everything. At ARCO Lock & Security, we offer 24/7 professional alarm monitoring services in Glendale, AZ—ensuring your home or business is never left vulnerable. From Sahuaro Ranch Park neighborhoods to Arrowhead Ranch commercial centers, our systems are designed to detect threats in real time and notify the right people instantly.


Unlike self-monitored alarms that rely on your phone and availability, our monitored systems use secure cellular signals and professional agents to respond to intrusions, fire, and other emergencies—even if you’re offline or out of state. It’s always-on protection that adapts to your lifestyle and your location.


We proudly serve both residential and commercial properties across Glendale, including areas near Westgate Entertainment District, Downtown Glendale, and the Historic Catlin Court district. Whether you’re protecting a retail shop, office, or your personal home, our systems are customized for your space and security risk.


When paired with our smart cameras and access control systems, alarm monitoring becomes part of a fully integrated solution that not only alerts but actively deters crime before it escalates. Our Glendale clients trust ARCO to keep eyes on what matters most—day or night, rain or shine.

  • Do I need alarm monitoring if I already have security cameras?

    Our monitoring includes intrusion alarms, door/window sensors, glass break detectors, motion sensors, smoke alarms, and carbon monoxide detection.


  • How fast is the response time in Glendale?

    Typical response times are under 30 seconds, with agents immediately alerting police or fire dispatch based on the triggered event.

  • Is cellular monitoring more reliable than landline?

    Yes, our systems use secure cellular connections that remain active during power outages or cut lines—unlike traditional landlines.


  • Can I manage my alarm system remotely?

    Absolutely. You can arm, disarm, and receive alerts through our mobile app—giving you total control from anywhere.


  • Do you offer monitoring for both homes and businesses in Glendale?

    Yes. We provide customized alarm monitoring solutions for both residential and commercial properties across the Glendale area.
