NoEntry by SONIS

What happens when a burglary occurs? A door or window has to be opened. The sound signatures were studied and the concept of NoEntry by Sonis was born.

Over the years the sound signature research results were documented and a database was created incorporating all measured parameters to create a unique, sophisticated algorithm and acoustic technology for intruder capture – eliminating the need for all passive infrared, door and window sensors. This groundbreaking innovation represents the first major technological breakthrough in home security since the invention of PIRs over 50 years ago.

The technology has been tested and approved by one of the world’s leading manufacturers. During discussions, it was agreed that a learning mode which captures badly fitted doors and windows should be developed. Comprehensive work was carried out to facilitate this feature achieving the ability to protect the entire property from one single and attractive unit.

After a decade of innovation and technical excellence patents were granted for the UK, EU and USA.
