PGST PG103-US4G-A Alarm System for Home Security: Supports GSM/4G+WiFi connectivity for remote monitoring
This PGST Alarm System is for the homeowner who wants to secure their property without a monthly contract. It's perfect for monitoring entry points like your front door or garage while you're at work.
Think of it not just as a security system, but as a reliable digital neighbor. The 120dB siren is loud enough that you'll hear the alert from your phone before your dog starts barking. You can arm it with your voice using Alexa when your hands are full with groceries.
The system works without WiFi using a SIM card, so a power outage won't leave you unprotected. The app sends clear, immediate notifications if a sensor is triggered, letting you check the live status instantly. It supports over 99 sensors, allowing you to start with the basics and expand coverage room by room.
