About Ajax Security Monitoring

A national resource for modern Ajax security, built around outcomes.

Installation, takeovers, monitoring options, and real support — coordinated by one sales desk for properties across the United States.

Ajax Security Monitoring is a national installation and monitoring resource for Ajax wired and wireless security systems, operated by Security First Alarm LLC. The site helps property owners and security buyers understand, design, and deploy modern Ajax intrusion protection — from new installations to takeovers of existing wired alarm equipment. We focus on outcomes rather than device counts: earlier awareness, clearer event verification through supported MotionCam photo verification, practical remote control, and layered protection that fits how a property is actually used.

This resource is built for a wide range of customers across the United States, including retail stores, restaurants and bars, warehouses, manufacturing facilities, multifamily properties, hotels, automotive dealerships, medical offices, schools and daycare centers, churches, offices, and property management teams — as well as homeowners who want clean, modern residential security. Whether a project is a single location or a multi-state rollout, one sales desk coordinates the assessment, design, installation, and ongoing support.

Security First Alarm LLC is an independent security provider. We coordinate licensed vendors where required and tailor every system through technical review, so compatibility, monitoring options, and regulatory acceptance are confirmed for the property and jurisdiction — never assumed. References to Ajax and Ajax products on this site are for identification and marketing of genuine Ajax security products and do not transfer or imply ownership of Ajax intellectual property.
