SA7M2BWF 4G GSM Alarm System with Tuya App Wi-Fi Dual Network

Dual-Network Security Hub with App Control

The SA7M2BWF 4G alarm combines cellular and Wi-Fi connectivity in one wall-mounted panel. It sends push alerts through the Tuya Smart app and supports remote arming or disarming from a phone. The controller accepts both wired and wireless sensors for doors, windows, motion and smoke.

The panel manages 7 wired defence zones and 99 wireless zones on the 433 MHz band. A 2.4-inch colour display shows zone status, arm state and event logs. The built-in keypad handles local control when the app is unavailable. Voice prompts guide setup and daily operation.

A rechargeable lithium battery keeps the system running during mains failure. The 4G LTE radio operates on standard cellular bands and falls back to GSM where LTE coverage is weak. Wi-Fi 802.11 b/g/n on 2.4 GHz provides a secondary path to the Tuya cloud. The enclosure suits indoor walls in homes, shops and small offices.
