Tuya WIFI GSM Alarm ER-T90
Product Introduction:
This alarm is a high-performance intelligent security technology product that utilizes dual GSM/4G+Wi-Fi communication networks to transmit alarm information. It features a 4.3-inch TFT full-touch color display, menu-based operation, voice prompts, and multiple language options. It connects to wireless sensors using advanced wireless technology and supports four wired zones with line-end resistors.
