What is SmartVOX® and how does it work?

SmartVOX® is designed for situations where clear warning is crucial: think fire, storm, intruders or evacuations. The system operates via wireless LoRa radio links and uses a mesh network: each device is both transmitter and amplifier at the same time, allowing you to cover an entire building without cabling.What is SmartVOX® and how does it work?

Messages are spoken via voice modules and are pre-recorded or compiled via voice generation. The system is operated via remote controls, hand-held detectors or fully automatically via inputs and software.

Thanks to a user-friendly app for Android and PC, you set every detail yourself: flash patterns, volumes, zones and message content. SmartVOX® also works autonomously in case of power failure thanks to its built-in battery.

As the exclusive Benelux distributor, 4K offers a complete range of SmartVOX® components, tailor-made advice and implementation support.
