Neruppu is a modern, offline-first physical security monitoring app that uses your device's sensors to detect and record security events.Features:
• Camera motion detection (front and back cameras)
• Microphone audio monitoring with automatic recording on noise bursts
• Accelerometer movement/vibration detection
• Ambient light change detection
• Optional Matrix remote alerts
• All data stored locally - no cloud required
The app runs as a foreground service ensuring continuous monitoring while providing optional encrypted remote notifications via Matrix when security events are detected.
Built with privacy and security in mind - all logs and media remain on your device unless you explicitly configure remote alerts.
