GSM Wireless Smart Burglar Alarm DIY Kit — Door & Motion Sensors, App/SMS Alerts, Two-Way Voice

Remote monitoring and alerting: if an intrusion occurs, the control unit emits a high-decibel alarm, automatically calls preset numbers, sends SMS notifications and pushes messages via the mobile app so you can view and respond from anywhere. Two-way voice intercom: place and receive calls, exchange voice messages and operate the system with SMS remote control for quick, intelligent interaction. Scalable protection: expand the system with up to 100 sensors — including PIR Detectors, Door sensor, Smoke Detector, CO Detector and more — to create a complete prevention and control setup. Scheduled arming/disarming: arming and disarming can be set according to your needs, allowing regular automatic operation to save time and eliminate daily repetition. Simple, user-friendly design: clean layout with environmentally friendly silicone keys that provide a comfortable touch feel.
