HomeSiren Jeweller is a smart indoor device that does more than alert alarms. It can also serve as a security status indicator, notify of door openings, and display delays when entering, leaving, and after an alarm. The device operates autonomously on pre-installed batteries for up to 5 years and uses the wireless Jeweller radio protocol to communicate with a hub or range extender at distances of up to 2,000m. HomeSiren Jeweller is protected at hardware and software levels and is easy to control via Ajax apps.
