GSM/2G/3G/4G Smart Home Burglar Alarm System — Tuya APP Control, Arm/Disarm (Optional Kit)

A smarter way to secure your home from the inside out. If an intruder opens a door or window, the system sounds a local alarm and pushes alert information to your mobile phone. The panel uses FHSS technology combined with information encryption to deliver top-tier anti-interference and enhanced security. It supports GSM / 2G / 3G / 4G multiple networks so the alarm remains effective across different conditions. Built-in GSM / 2G / 3G / 4G signal monitoring will notify you if the signal is lost or becomes weak. The system also monitors door and window switch status and will warn you if any are open when you set Arm (or Home Arm).
