Designed to provide all-round anti-burglar protection for your home, office or property, the 4.3'' Touch Screen SOS GSM 4G WiFi Smart Security System is a cutting-edge intelligent solution integrated with Tuya IoT technology. Combining dual-network connectivity, intuitive operation and multi-scene adaptability, it effectively deters intrusions and ensures your peace of mind whether you are at home or away.

The system features a 4.3-inch high-definition touch screen, which offers a user-friendly interface with clear icons and simple navigation. Even the elderly and children can easily arm, disarm or adjust settings without complicated operations. Equipped with a prominent SOS emergency button, it allows for instant help calls in case of danger—just one press will send alerts to preset contacts, ensuring timely response in emergencies such as burglaries, fires or personal threats.

With dual GSM 4G and WiFi connectivity, the system eliminates the risk of signal interruption. If the WiFi network fails, it automatically switches to 4G GSM to ensure continuous operation, minimizing security loopholes caused by network outages. It supports up to 5 groups of alarm phone calls and 5 groups of SMS notifications, sending real-time alerts to your smartphone the moment an intrusion is detected by connected sensors.

Seamlessly integrated with Tuya Smart App, the system enables remote monitoring and control via your iOS or Android device. You can check the system status, arm/disarm the device, view alarm logs and even link it with other Tuya smart devices (such as smart lights and sirens) for a more comprehensive security ecosystem. It supports up to 99 wireless accessories, including door/window sensors and motion detectors, covering every corner of your space with 30-50 meters of detection distance.
