G20 WiFi GSM Security Alarm System — Tuya Smart Wireless/Wired Home Burglar Protection Kit with IP Camera, Light & Siren

Control the G20 alarm remotely using Tuya Smart or Smart Life apps. The system delivers free push notifications over Wi‑Fi and will trigger the built‑in siren and light when an intrusion is detected. Setup is simple: press the Wi‑Fi configuration button on the host, the unit will flash blue rapidly and enter Smart Mode for Wi‑Fi pairing. If your home has no Wi‑Fi, an unstable connection, or the router loses power, insert a GSM SIM card to keep the alarm reachable and operating via mobile network.
