You can add new devices and scale your system as space requirements grow — without compatibility issues, complex setup, or redesigning everything from scratch. INSTANT ALERTS WITH VISUAL PROOF You don't miss important events — you know exactly when and how to respond. When an intrusion, fire, or water leak is detected, the app sends a critical alert that breaks through Do Not Disturb mode. Visual alarm verification from Ajax cameras or MotionCam detectors helps you quickly understand what's happening on site. VIDEO SURVEILLANCE YOU CAN TRUST Watch live video or browse the archive directly in the app. Footage is synchronized with system events, giving you a clear visual context for every alarm and complete situational awareness. To protect your privacy, video streams use secure proprietary transmission technology, while passwordless camera authentication minimizes the risk of unauthorized access. AUTOMATION FOR ENHANCED SECURITY AND ROUTINES Set your system to operate automatically. Change security modes on a schedule, turn on lighting when motion is detected, shut off water in case of a leak, or control locks, gates, heating, and appliances. Automation scenarios run in the background — even without an internet connection — while you focus on your day. PROFESSIONAL RESPONSE, ONE TAP AWAY Connect your system to a monitoring company to access professional security services with fast alarm response. The largest alarm receiving centers and a wide range of CMS software in more than 180 countries support Ajax systems. In an emergency, press the in-app panic button to instantly transmit the event and your smartphone's location to the rapid response unit. • • • Ajax equipment is required to use the app. Devices are available from authorized Ajax Systems partners.
