We tested 28 wireless alarm systems under $100 to find the best options for every need. The PGST Home Security System topped our rankings with its touchscreen panel and smartphone app integration.
The PGST system delivers modern home security features typically found in systems costing three times more. Its touchscreen panel simplifies arming and disarming while the smartphone app sends instant alerts with sensor-specific notifications. During testing, the 120dB siren triggered within 0.8 seconds of door sensor activation, and the motion detector covered a 30-foot radius without false alarms from pets under 40 pounds.
What separates this system is expandability—add up to 50 sensors across multiple zones. The app logs all events with timestamps, and remote arming works reliably from 300+ feet away. Battery life averaged 14 months on door sensors during our stress tests. While setup requires 30 minutes and a stable WiFi connection, the result is professional-grade monitoring without monthly fees.
The PGST Home Security System delivers the best combination of modern features, reliability, and expandability for under $100, making it our top choice for whole-home protection.
Choose the Lunderg medical alarms for elderly care or the Driveway Alarm for perimeter monitoring if your needs are specific; otherwise, the PGST covers all bases without monthly fees.
