Our journey began back in 2008 by our CEO, Stephen Roberts. As a victim of asset theft, he became very disgruntled at the misery such thefts caused.

In the winter of 2016, after many years of research, the concept and prototype of the ‘Smart-Lead’ began. The ‘Smart-Lead’ is a low cost, worldwide GPS track & Trace with the remote immobilisation technology ‘built in’.

The Sentry R & D team have a combined-working experience of 95yrs. We are proud of our achievement in developing a much-needed product. Our technology is ‘built in’ to many types of Electrical & Mechanical equipment. As a Company our drive is to provide high specification at a low price point to all of our product range.

Let’s stop the theft epidemic that hikes all our insurance costs. Help us to help you.
