Analytics. The company's first product, Sure Bell is a revolutionary security solution developed for the safety of you and your family. It uses smart sensors, optics and intelligent software to ensure that you are alerted of any activity around your door, round the clock. It also allows you to visually communicate with strangers, even when you’re away. Sure Bell uses smart technology to optimise bandwidth for call connectivity and reduce storage required by detecting and recording only instances of motion outside your door.
