Our Mission: To make home security simple and affordable for all

Sonis Founder Bill Marr spent his career in the defence industry using advanced sonar techniques to build submarine hunting systems for major defence contractors.  Bill recognised the limitations of the existing intruder alarm systems on the market and that sonar techniques could be applied to make a revolutionary new alarm.

Sonis Smart Security Limited was born to use sound analysis as the core of a new concept in intruder alarms that does away with conventional sensors and their downsides.  The result is NoEntry, a single palm-sized unit, which protects an entire home.  In a fraction of a second, it can detect a door or window being opened anywhere in the property, triggering an alert before the intruder gains entry.
