W18 4G GSM Smart Home Burglar Alarm System with Motion Sensor & 110dB Siren

The W18 4G GSM smart alarm secures homes and valuable assets with motion detection and powerful audible warnings. On activation it produces a 110dB alert—via its built-in siren and compatible 110dB wired siren—to warn neighbors and deter intruders. A backup battery keeps the system running for up to 8 hours if mains power is lost. Designed for stable, high-end performance, the unit also features an auto-dialer that will call up to 6 designated phone numbers in the event of a security breach.
