Description

A Wireless Alarm System (GSM-based) is a modern home and business security solution that uses wireless sensors and GSM (Global System for Mobile Communication) technology to detect intrusions, fire, gas leaks, or emergencies — and instantly send alerts via SMS or phone calls to the user’s mobile phone. It’s ideal for homes, offices, shops, warehouses, and remote locations where internet access may be limited but mobile network coverage is available. 📡 What Is a Wireless GSM Alarm System? A GSM Alarm System is a standalone, wireless security system that communicates through a SIM card (just like a mobile phone) to notify the user of alarms via SMS, voice calls, or mobile apps, without needing Wi-Fi or a landline.
