PGST PG103-US4G-C Alarm System for Home Security: Real-time alerts with 120dB siren
This 12-piece PGST alarm system is for the homeowner who wants a simple, reliable shield without a monthly contract. You need to know if a package arrives, if a child comes home late, or if a pet wanders into a restricted area. While many systems focus on deterring break-ins, this kit offers peace of mind for daily routines, letting you monitor your space like a trusted neighbor.
The system connects via GSM/4G and WiFi, so alerts reach your phone even if your internet drops—a lifesaver during storms or outages. You can arm it remotely via the Smart Life app or use Alexa voice commands, making it easy to secure the house as you leave. The 120dB siren is loud enough to startle intruders, but the real value is in the instant notifications; you will see a door sensor trigger before your dog barks. With support for 99+ sensors, it grows with your needs, from a small apartment to a full house.
