433MHz Tuya GSM Wireless Home Burglar Alarm System — High Sound Smart House Control

Reliable alerts: The GSM alarm sends APP push and SMS notifications for external power failure and low built-in battery. Restored external power triggers an APP push, and tamper attempts generate an SMS alert. Phone contacts: Up to 5 preset alarm phone numbers can be stored; SMS and call (dial) notifications can be switched on or off independently for each group. Scheduled arming: Program automatic arm and disarm times so the system follows your daily routine. Adjustable delays: Configure both arm delay and alarm delay to suit your preferences. Camera support: Integrate a camera for instant remote monitoring during a break-in and use the speaker function to speak and deter intruders.
