If you have an old Android device lying around, this app lets you repurpose it into a fully functional security system. It uses the device’s camera to detect movement and automatically starts recording whenever activity is spotted. Key features: Motion Detection: Accurate tracking to trigger recordings instantly. Cloud Backup: Automatically uploads your recordings directly to your Google Drive, so your footage stays safe even if the device is damaged or stolen. Lightweight: Built with modern Android architecture for better battery management. I built this specifically for people who want a private, DIY surveillance solution without recurring monthly subscription fees.   submitted by   /u/Fabio-Santos1990 [link]   [comments]
