Light Revolution by HeatSig

Safer, smarter buildings, from the lights.

The same heat sensing as SORVA, across every room of a building: inactivity alerts, occupancy and energy data. No cameras and no wearable devices.

A bright, quiet building lobby

Where it works

One fitting, many kinds of building

  • Care homes and hospitals

    Inactivity alerts, patient management, footfall and space control.

  • Hotels

    Occupancy detection, guest comfort and facility control.

  • Shops and malls

    Crowd control, footfall and how people move.

  • Offices and facilities

    Occupancy and energy, security checks, people and building management.

Why buildings choose it

Do less, achieve more

  • No cameras, no wearables

    Heat signatures only, so it fits wards, rooms and washrooms without privacy worries.

  • In the lights you already need

    Works day and night through standard overhead fittings: fewer devices and cables.

  • Live data, quick alerts

    Real-time insight into how spaces are used, and instant alerts for inactivity.

  • Lower energy use

    Occupancy data links with building management to switch off empty zones.
