433MHz GSM Wireless Home Alarm System — Tuya App Control for Burglar & Safety Security

Compact wireless alarm system supporting 433MHz sensors and GSM alerts. Door/window sensors mount on openings and will trigger a loud siren when opened; the system also issues app notifications and text messages. With a SIM card installed in the main unit it can place voice calls to alert you. Passive infrared (PIR) human-body motion sensors provide infrared-based detection — when movement is detected the system plays a warning voice and will both send a text message and call you. Fire and gas safety are covered too: smoke detectors, carbon monitor detectors, and gas detectors will notify you in cases of fire or gas leakage. Multiple operating modes let you customize behavior — for example, set a mute mode for when you are home and an armed protection mode when you go out. You can arm or disarm the protection remotely using the Tuya mobile app.
