PG-103 Wireless GSM Smart Home Alarm Kit with Metal Window/Door Detector — TUYA APP Compatible, Loud Siren

The PG-103 wireless GSM alarm system protects doors and windows with a metal detector sensor that triggers an immediate loud alarm when opened. The system will also send a text message through the app to notify you, and if a SIM card is installed the unit can place a voice call to alert you. Add the PIR motion sensor (a human-body infrared detector) to cover interior movement: when it senses someone approaching it will play a warning voice and additionally send a text message and make a call if configured. This kit is compatible with smoke detectors, carbon monoxide monitors and gas detectors so it can warn you in the event of fire or a gas leak. Flexible arming options let you choose a mute/home mode when you are inside and a full protection/away mode when you leave. You can also arm or disarm the system remotely using the TUYA mobile app.
