About Us
Who We are
Sonis Smart Security Ltd is a UK security Technology company based in Dunfermline, Scotland. We design early-warning protection systems that help stop break-ins before they happen. Our flagship product, NoEntry, is built on advanced patented disturbance-detection technology and engineered to protect homes together with a version for caravans and motorhomes.
Our mission is simple: reliable security accessible to everyone- without wiring, drilling, or complicated setups.
Our approach to Security.
Traditional alarms activate after an intruder is already inside. Sonis’ technology activates before the burglar is inside the property.
The early warning approach gives customers time to act, reduces damage, and helps deter intruders before they get inside.
We have developed two dedicated versions – one for homes and one for caravans & motorhomes providing early-warning security when a door or window is opened.

NoEntry is designed to be:

Easy to Install
no tools or wiring

Flexible
Two dedicated systems, designed for different environments

Accessible
no subscriptions or hidden fees

UK Engineering, UK manufacturing, UK Support
We design, test, and manufacture our products in the UK. Every NoEntry unit produced through trusted UK manufacturing partners.
Being UK-made allows us to deliver technology that feels premium, performs reliably, and is backed by UK based customer support.
