INSTANT ALERTS WITH VISUAL PROOF You don't miss important events — you know exactly when and how to respond.

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.
