FAQ: For Preppers
Q: Is this an actual earthquake early warning system?
A: No. It's a high-sensitivity vibration tripwire. It detects tremors, forced entry, and structural vibration at your location and triggers a 120dB siren + LED - no internet needed.

Q: Does it need Wi-Fi or power?
A: No. It's 9V battery-operated and analog. It works when the grid and cell towers are down.
