W18 Smart GSM Home Security Alarm System — Motion, Smoke, Door & Window Sensors, 110dB Siren

Comprehensive, expandable home protection that notifies you instantly: the W18 Smart GSM alarm works with motion detectors, smoke sensors and door/window sensors to send mobile alerts when activity is detected. Install it yourself—no tools or professional help required—and add devices to suit any house or apartment. High-volume warning: on intrusion the system triggers a 110dB alarm (built-in siren plus 110dB wired siren) to warn neighbors and deter burglars. Multi-language voice support with six selectable languages: English, German, Italian, Russian, Spanish, French. Continuous coverage and fail-safe power: professional 24/7 monitoring is supported, and the internal backup battery keeps the system operating for 8 hours if mains power is lost. In an emergency the auto-dialer will call up to 6 designated phone numbers to make sure alerts reach the right people.
