WHO IS AJAX?

Founded in 2011, Ajax creates wireless alarm and fire systems with JEWELER wireless technology, allowing you to securely monitor all connected network devices. Ajax offers solutions for the home, office, or commercial business, managed via an app that's always up-to-date and compatible with iOS and Android systems. Ajax devices are easy to install—it takes just 15 seconds to connect the control panel to the sensors. They can also be integrated with surveillance cameras, have a virtually zero error rate, and, in the event of danger, send a notification (text message, push notification, or call) in less than 150 milliseconds.
Ajax alarm systems use cutting-edge wireless technology, making all products reliable and always connected. In addition to excellent performance, Ajax systems stand out for their modern and elegant design.
