Lockdown Alert Controller is a secure mobile app for authorized personnel to trigger GSM relay-based commands (e.g., lockdown alerts, lights, gates) at assigned sites. Users are assigned by an administrator, self-registration and guest access are not supported for security reasons. The app displays only the buttons the user has permission to access, supporting multi-command, toggle, and timed actions. Visual confirmations and real-time push notifications ensure rapid response during emergencies. This app is part of the AIS Security platform and is intended for schools and institutions requiring fast, reliable, and role-controlled device operations.
